PLANT CELL REPORTS 2024; 43:127. [PMID: 38652203 DOI: 10.1007/s00299-024-03212-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/23/2024] [Accepted: 04/01/2024] [Indexed: 04/25/2024]
Abstract
KEY MESSAGE This study identified 16 pyridoxal phosphate-dependent decarboxylases in olive at the whole-genome level, conducted analyses on their physicochemical properties, evolutionary relationships and characterized their activity. Group II pyridoxal phosphate-dependent decarboxylases (PLP_deC II) mediate the biosynthesis of characteristic olive metabolites, such as oleuropein and hydroxytyrosol. However, there have been no report on the functional differentiation of this gene family at the whole-genome level. This study conducted an exploration of the family members of PLP_deC II at the whole-genome level, identified 16 PLP_deC II genes, and analyzed their gene structure, physicochemical properties, cis-acting elements, phylogenetic evolution, and gene expression patterns. Prokaryotic expression and enzyme activity assays revealed that OeAAD2 and OeAAD4 could catalyze the decarboxylation reaction of tyrosine and dopa, resulting in the formation of their respective amine compounds, but it did not catalyze phenylalanine and tryptophan. Which is an important step in the synthetic pathway of hydroxytyrosol and oleuropein. This finding established the foundational data at the molecular level for studying the functional aspects of the olive PLP_deC II gene family and provided essential gene information for genetic improvement of olive.

Abstract
Morphine plays a critical regulatory role in both simple and complex plant species. Dopamine is a critical chemical intermediate in the morphine biosynthetic pathway and may have served as a primordial agonist in developing catecholamine signaling pathways. While dopamine remains the preeminent catecholamine in invertebrate neural systems, epinephrine is the major product of catecholamine synthetic pathways in vertebrate species. Given that the enzymatic steps leading to the generation of morphine are similar to those constraining the evolutionary adaptation of the biosynthesis of catecholamines, we hypothesize that the emergence of these more advanced signaling pathways was based on conservation and selective "retrofitting" of pre-existing enzyme activities. This is consistent with observations that support the recruitment of enzymatically synthesized tetrahydrobiopterin (BH4), which is a cofactor for tyrosine hydroxylase, the enzyme responsible for dopamine production. BH4 is also an electron donor involved in the production of nitric oxide (NO). The links that coordinate BH4-mediated NO and catecholaminergic-mediated processes provide these systems with the capacity to regulate numerous downstream signaling pathways. We hypothesize that the evolution of catecholamine signaling pathways in animal species depends on the acquisition of a mobile lifestyle and motivationally driven feeding, sexual, and self-protective responses.

Abstract
Fusarium solani, one of the main pathogenic fungi involved in apple replant disease (ARD), is a serious threat to apple growth and development. Dopamine and tyrosine decarboxylase (TyDC), a key enzyme in the dopamine synthesis pathway, have been reported to play an active role in plant responses to biotic and abiotic stresses, but little is known about the functions of dopamine and Malus domestica TyDC (MdTyDC) in the interaction between F. solani and apple roots. In this study, seedlings treated with exogenous dopamine and apple plants overexpressing MdTyDC were inoculated with F. solani; both treatments reduced the root system damage caused by F. solani. After inoculation with F. solani, exogenous dopamine increased dopamine content in the seedlings; alleviated the inhibition of biomass accumulation; increased root metabolic activity, photosynthetic efficiency, and antioxidant enzyme activities; reduced reactive oxygen species accumulation; and upregulated the expression of genes encoding chitinase, β-1,3-glucanase, and pathogenesis-related proteins. Similar results were observed in MdTyDC-overexpressing apple plants. In addition, the overexpression of MdTyDC increased tyramine content and the deposition of cell wall-bound amines in roots. Overall, our results reveal that exogenous dopamine and overexpression of MdTyDC enhance apple resistance to F. solani, which is an important application for the prevention of ARD.

Abstract
The RgTyDCs possess typical decarboxylase functional activity in vitro and in vivo and participate in acteoside biosynthesis in R. glutinosa, positively controlling its production via activated acteoside/tyrosine-derived pathways. Acteoside is an important ingredient in Rehmannia glutinosa and an active natural component that contributes to human health. Tyrosine decarboxylase (TyDC) is thought to play an important role in acteoside biosynthesis. Several plant TyDC family genes have been functionally characterized and shown to play roles in some bioactive metabolites' biosynthesis by mediating the decarboxylation of L-tyrosine and L-dihydroxyphenylalanine (L-DOPA); however, one TyDC (named RgTyDC1) in R. glutinosa has been identified to date, but the family genes that contribute to acteoside biosynthesis remain largely characterized. Here, by in silico and experimental analyses, we isolated and identified three RgTyDCs (RgTyDC2 to RgTyDC4) in this species; these genes' sequences showed 50.92-82.55% identity, included highly conserved domains with homologues in other plants, classified into two subsets, and encoded proteins that localized to the cytosol. Enzyme kinetic analyses of RgTyDC2 and RgTyDC4 indicated that they both efficiently catalysed L-tyrosine and L-dopa. The overexpression of RgTyDC2 and RgTyDC4 in R. glutinosa, which was associated with enhanced TyDC activity, significantly increased tyramine and dopamine contents, which was positively correlated with improved acteoside production; moreover, the overexpression of RgTyDCs led to upregulated expression of some other genes-related to acteoside biosynthesis. This result suggested that the overexpression of RgTyDCs can positively activate the molecular networks of acteoside pathways, enhancing the accumulation of tyramine and dopamine, and promoting end-product acteoside biosynthesis. Our findings provide an evidence that RgTyDCs play vital molecular roles in acteoside biosynthesis pathways, contributing to the increase in acteoside yield in R. glutinosa.

Abstract
Apple replant disease (ARD) is a soil-borne disease that leads to economic losses due to reduced plant growth and diminished fruit yields. Dopamine is involved in interactions between plants and pathogens. However, it remains unclear whether dopamine can directly stimulate defense responses to ARD. In this study, an exogenous dopamine treatment and dopamine synthetase MdTYDC (tyrosine decarboxylase) transgenic plants were used to verify the role of dopamine in treating ARD. First, 2-year-old apple trees (Malus domestica cv. Fuji), grafted onto rootstock M26, were grown in replant soils. The addition of dopamine (100 μM) to the soil promoted seedling growth and changed the accumulation of mineral elements in plants in replant soils. Such supplementation improved the activity of invertase, urease, proteinase and phosphatase under replant conditions. Sequencing analysis of 16S rDNA and internal transcribed spacer (ITS) rDNA revealed that dopamine had a slight influence on bacterial diversity but had an obvious effect on the fungal diversity in replant soils. The application of dopamine to replant soil changed the composition of bacterial and fungal communities. Second, overexpression of MdTYDC in apple plants alleviated the effects of ARD. MdTYDC transgenic lines exhibited mitigated ARD through inhibited degradation of photosynthetic pigment, maintaining the stability of photosystems I and II and improving the antioxidant system. Furthermore, overexpression of MdTYDC improved arbuscular mycorrhizal fungi colonization by improving the accumulation of soluble sugars under replant conditions. Together, these results demonstrated that dopamine enhances the tolerance of apples to ARD.

Abstract
Dopamine (3-hydroxytyramine or 3,4-dihydroxyphenethylamine) has many functions in animals, but also shows several other functions in plants. Since the discovery of dopamine in plants in 1968, many studies have provided insight into physiological and biochemical functions, and stress responses of this molecule. In this review, we describe the biosynthesis of dopamine, as well as its role in plant growth and development. In addition, endogenous or exogenously applied dopamine improved the tolerance against several abiotic stresses, such as drought, salt, and nutrient stress. There are also several studies that dopamine contributes to the plant immune response against plant disease. Dopamine affects the expression of many abiotic stresses related genes, which highlights its role as a multi-regulatory molecule and can coordinate many aspects of plant development. Our review emphasized the effects of dopamine against environmental stresses along with future research directions, which will help improve the yield of eco-friendly crops and ensure food security.

Abstract
Chelidonium majus is a traditional medicinal plant, which commonly known as a rich resource for the major benzylisoquinoline alkaloids (BIAs), including morphine, sanguinarine, and berberine. To understand the biosynthesis of C. majus BIAs, we performed de novo transcriptome sequencing of its leaf and root tissues using Illumina technology. Following comprehensive evaluation of de novo transcriptome assemblies produced with five programs including Trinity, Bridger, BinPacker, IDBA-tran, and Velvet/Oases using a series of k-mer sizes (from 25 to 91), BinPacker was found to produce the best assembly using a k-mer of 25. This study reports the results of differential gene expression (DGE), functional annotation, gene ontology (GO) analysis, classification of transcription factor (TF)s, and SSR and miRNA discovery. Our DGE analysis identified 6,028 transcripts that were up-regulated in the leaf, and 4,722 transcripts that were up-regulated in the root. Further investigations showed that most of the genes involved in the BIA biosynthetic pathway are significantly expressed in the root compared to the leaf. GO analysis showed that the predominant GO domain is "cellular component", while TF analysis found bHLH to be the most highly represented TF family. Our study further identified 10 SSRs, out of a total of 39,841, that showed linkage to five unigenes encoding enzymes in the BIA pathway, and 10 conserved miRNAs that were previously not detected in this plant. The comprehensive transcriptome information presented herein provides a foundation for further explorations on study of the molecular mechanisms of BIA synthesis in C. majus.

Abstract
The overuse of antibiotics in animal agriculture and medicine has caused a series of potential threats to public health. Macleaya cordata is a medicinal plant species from the Papaveraceae family, providing a safe resource for the manufacture of antimicrobial feed additive for livestock. The active constituents from M. cordata are known to include benzylisoquinoline alkaloids (BIAs) such as sanguinarine (SAN) and chelerythrine (CHE), but their metabolic pathways have yet to be studied in this non-model plant. The active biosynthesis of SAN and CHE in M. cordata was first examined and confirmed by feeding 13C-labeled tyrosine. To gain further insights, we de novo sequenced the whole genome of M. cordata, the first to be sequenced from the Papaveraceae family. The M. cordata genome covering 378 Mb encodes 22,328 predicted protein-coding genes with 43.5% being transposable elements. As a member of basal eudicot, M. cordata genome lacks the paleohexaploidy event that occurred in almost all eudicots. From the genomics data, a complete set of 16 metabolic genes for SAN and CHE biosynthesis was retrieved, and 14 of their biochemical activities were validated. These genomics and metabolic data show the conserved BIA metabolic pathways in M. cordata and provide the knowledge foundation for future productions of SAN and CHE by crop improvement or microbial pathway reconstruction.

Abstract
Alkaptonuria is an inherited disease that is caused by homogenticate accumulation. Deficiency or mutation in Homogentisate 1,2
dioxygenase gene (chromosome 3q21-q23) leads to production of incorrectly folded or truncated enzyme. Several studies indicated that
competitive inhibitors of Homogentisate 1,2 dioxygenase like Nitisinone could be used for Alkaptonuria treatment. Therefore, it is of
interest to design better inhibitors of the enzyme. We used subset 3_p.0.5 from Zinc database as the virtual screening library by PyRx
software relaying on Lamarckian genetics algorithm. Top 10 hits with more efficient binding affinity were analyzed and hit No#5 and No#
7 was selected for further design. In Lig No#5, we decreased the hydrophobicity by adding oxygen in the hydrophobic tail of the molecule
at positions C5 and C10. The new compound of (2Z, 5Z, 8Z)-6,9-Dihydroxy-2-(2-hydroxy-5-oxo-1,3-cyclohexadien-1-yl)-2,5,8-decatrienoic
acid satisfied Lipinski rules as well as PhysChem and FafDrugs filters. Moreover, the modified version of Lig No# 7 with the IUPAC name
of [2-(Carboxymethyl)-3,5-dihydroxyphenyl] acetic acid satisfies the Lipisnki, FafDrugs and Physchem.

Abstract
Wounding is required to be made in the walls of the green seed pod of Opium poppy prior exudation of latex. To withstand this kind of trauma plants regulate expression of some metabolites through an induced transcript level. 167 unique wound-inducible ESTs were identified by a repetitive round of cDNA subtraction after 5 hours of wounding in Papaver somniferum seedlings. Further repetitive reverse northern analysis of these ESTs revealed 80 transcripts showing more than two fold induction, validated through semi-quantitative RT-PCR & real time expression analysis. One of the major classified categories among identified ESTs belonged to benzylisoquinoline transcripts. Tissue specific metabolite analysis of benzylisoquinoline alkaloids (BIAs) in response to wounding revealed increased accumulation of narcotine and papaverine. Promoter analysis of seven transcripts of BIAs pathway showed the presence of W-box cis-element with the consensus sequence of TGAC, which is the proposed binding site for WRKY type transcription factors. One of the Wound inducible 'WRKY' EST isolated from our subtracted library was made full-length and named as 'PsWRKY'. Bacterially expressed PsWRKY interacted with the W-box element having consensus sequence TTGACT/C present in the promoter region of BIAs biosynthetic pathway genes. PsWRKY further activated the TYDC promoter in yeast and transiently in tobacco BY2 cells. Preferential expression of PsWRKY in straw and capsule and its interaction with consensus W-box element present in BIAs pathway gene transcripts suggest its possible involvement in the wound induced regulation of BIAs pathway.

Abstract
Morphine biosynthesis in relatively simple and complex integrated animal systems has been demonstrated. Key enzymes in the biosynthetic pathway have also been identified, that is, CYP2D6 and COMT. Endogenous morphine appears to exert highly selective actions via novel mu opiate receptor subtypes, that is, mu3,-4, which are coupled to constitutive nitric oxide release, exerting general yet specific down regulatory actions in various animal tissues. The pivotal role of dopamine as a chemical intermediate in the morphine biosynthetic pathway in plants establishes a functional basis for its expansion into an essential role as the progenitor catecholamine signaling molecule underlying neural and neuroendocrine transmission across diverse animal phyla. In invertebrate neural systems, dopamine serves as the preeminent catecholamine signaling molecule, with the emergence and limited utilization of norepinephrine in newly defined adaptational chemical circuits required by a rapidly expanding set of physiological demands, that is, motor and motivational networks. In vertebrates epinephrine, emerges as the major end of the catecholamine synthetic pathway consistent with a newly incorporated regulatory modification. Given the striking similarities between the enzymatic steps in the morphine biosynthetic pathway and those driving the evolutionary adaptation of catecholamine chemical species to accommodate an expansion of interactive but distinct signaling systems, it is our overall contention that the evolutionary emergence of catecholamine systems required conservation and selective "retrofit" of specific enzyme activities, that is, COMT, drawn from cellular morphine expression. Our compelling hypothesis promises to initiate the reexamination of clinical studies, adding new information and treatment modalities in biomedicine.

Abstract
Medicinal and aromatic plants have always been intimately linked with human health and culture. Plant-derived medicines constitute a substantial component of present day human healthcare systems in industrialized as well as developing countries. They are products of plant secondary metabolism and are involved in many other aspects of a plant's interaction with its immediate environment. The genetic manipulation of plants together with the establishment of in vitro plant regeneration systems facilitates efforts to engineer secondary product metabolic pathways. Advances in the cloning of genes involved in relevant pathways, the development of high throughput screening systems for chemical and biological activity, genomics tools and resources, and the recognition of a higher order of regulation of secondary plant metabolism operating at the whole plant level facilitate strategies for the effective manipulation of secondary products in plants. Here, we discuss advances in engineering metabolic pathways for specific classes of compounds in medicinal and aromatic plants and we identify remaining constraints and future prospects in the field. In particular we focus on indole, tropane, nicotine, isoquinoline alcaloids, monoterpenoids such as menthol and related compounds, diterpenoids such as taxol, sequiterpenoids such as artemisinin and aromatic amino acids.

Abstract
Remarkable progress on the biology of plant secondary metabolism has recently been realized. The application of advanced biochemistry, molecular, cellular, and genomic methodologies has revealed biological paradigms unique to the biosynthesis of secondary metabolites, including alkaloids, flavonoids, glucosinolates, phenylpropanoids, and terpenoids. The use of model plant systems has facilitated integrative research on the biosynthesis and regulation of each group of natural products. The model legume, Medicago truncatula Gaertn., plays a key role in studies on phenylpropanoid and flavonoid metabolism. Mint ( Mentha × piperita L.) and various conifers are the systems of choice to investigate terpenoid metabolism, whereas members of the mustard family (Brassica spp.) are central to work on glucosinolate pathways. Arabidopsis thaliana (L.) Heynh. is also used to study the biosynthesis of most secondary compounds, except alkaloids. Unlike other categories of secondary metabolites, the many structural types of alkaloids are biosynthetically unrelated. The biology of each group is unique, although common paradigms are also apparent. Opium poppy ( Papaver somniferum L.) produces a large number of benzylisoquinoline alkaloids and has begun to challenge Madigascar periwinkle ( Catharanthus roseus (L.) G. Don), which accumulates monoterpenoid indole alkaloids, as the most versatile model system to study alkaloid metabolism. An overview of recent progress on the biology of plant alkaloid biosynthesis, with a focus on benzylisoquinoline alkaloid pathways in opium poppy and related species, highlights the emergence of opium poppy as an important model system to investigate secondary metabolism.

Abstract
The catecholamine compounds in potato (Solanum tuberosum L.) leaves and tubers have been identified by gas chromatography coupled to mass spectrometry (GC-MS) measurements. The finding that the catecholamine level is dramatically increased upon tyrosine decarboxylase (TD) overexpression potentiates the investigation on their physiological significance in plants. It was then evidenced that catecholamines play an important role in regulation of starch-sucrose conversion in plants. In this paper we investigated catecholamine biosynthetic pathway in potato plants exposed to the different stress conditions. The activation of TD (EC 4.1.1.25), tyrosine hydroxylase (TH, EC 1.14.18.1) and l-Dopa decarboxylase (DD, EC 4.1.1.25) was a characteristic feature of the potato leaves treated with abscisic acid (ABA). In high salt condition only TD activity was increased and in drought both TH and DD were activated. UV light activated predominantly DD activity. Leaves of plants grown in the dark and in red light circumstances were characterized by significantly decreased activities of all the three enzymes whereas those grown in cold were characterized by the decreased activity of DD only. In all, stress conditions the normetanephrine level and thus catecholamine catabolism was significantly decreased. Increased catecholamine level in TD-overexpressing potato resulted in enhanced pathogen resistance. Our data suggest that plant catecholamines are involved in plant responses towards biotic and abiotic stresses. It has to be pointed out that this is the first report proposing catecholamine as new stress agent compounds in plants.

Abstract
In human and animal cells, the catecholamines are involved in glycogen mobilization. Since the compounds are found in a potato, their function in starch mobilization was hypothesized. In order to verify this hypothesis, the transgenic potato plants Solanum tuberosum L. cv. Desiree overexpressing tyrosine decarboxylase (TD EC 4.1.1.25) cDNA from parsley has been generated. The cDNA expression was judged by the northern blot analysis and the enzyme activity measurements. Four independent transgenic lines with the highest TD mRNA expression were selected and analyzed. The expected substantial decrease in tyrosine content was followed by significant increase in tyramine and dramatic enhancement of norepinephrine synthesis was detected. The level of L-3,4-dihydroxyphenylalanin (L-Dopa) was only slightly increased and dopamine significantly decreased in most cases in these plants. The increase in norepinephrine was accompanied by changes in carbohydrate metabolism. The significant increase in glucose and sucrose and the decrease in starch content were characteristic features of TD overexpressed transgenic potato tubers. The features mentioned above indicate that catecholamines potentiate starch mobilization in potato plants in common with animal cells. The decrease in tyrosine content in transgenic plants is also compensated by significant increase in chlorogenic acid synthesis thus potentially increasing the antioxidant capacity of transgenic tubers. The glycoalkaloids content is changed in the transformants. This may originate from glucose accumulation and glycolysis activation. The obtained transgenic potato provides material for further detailed studies of the physiological function of catecholamines in plants.

Abstract
Opium poppy (Papaver somniferum) produces a large number of benzylisoquinoline alkaloids, including morphine and sanguinarine, derived from tyrosine via the branch-point intermediate (S)-reticuline. Molecular clones for the three methlytransferases involved in (S)-reticuline biosynthesis, (S)-norcoclaurine-6-O-methyltransferase (6OMT), (S)-3'-hydroxy-N-methylcoclaurine-4'-O-methyltransferase (4'OMT), and (S)-coclaurine N-methyltransferase (CNMT), were isolated from opium poppy and shown to share extensive homology with the corresponding cDNAs from Japanese goldthread (Coptis japonica). These cDNAs were used together with previously isolated clones for tyrosine/dopa decarboxylase (TYDC), (S)-N-methylcoclaurine-3'-hydroxylase (CYP80B1), berberine bridge enzyme, (BBE), (7S)-salutaridinol 7-O-acetyltransferase (SAT), and codeinone reductase (COR), to compare the accumulation of gene transcripts encoding eight alkaloid biosynthetic enzymes in opium poppy. Transcript levels generally increased in developing seedlings and were consistently high in stems and flower buds, but were more variable in roots and leaves of mature plants. The accumulation of each transcript, with the exception of COR, showed a marked induction in response to elicitor treatment or wounding of cultured cells. Specific gene transcript levels often correlated with the accumulation of morphine or sanguinarine, with notable exceptions. Our data suggest some degree of coordination in the developmental and inducible regulation of alkaloid biosynthetic genes in opium poppy.

Abstract
Dopamine, norepinephrine, and normetanephrine were identified by GC-MS in potato (Solanum tuberosum L.) plants, the latter was new for plants. The highest amount of catecholamines was found in leaves. A developmental stage dependent variation in potato leaf catecholamines accumulation was also observed with highest level in third leaves. Catecholamine contents decrease during cold storage of tubers to undetectable levels. Mechanical wounding of leaves led to a small increase in the level of catecholamines investigated.

Abstract
Characterization of many of the major gene families responsible for the generation of central intermediates and for their decoration, together with the development of large genomics and proteomics databases, has revolutionized our capability to identify exotic and interesting natural-product pathways. Over the next few years, these tools will facilitate dramatic advances in our knowledge of the biosynthesis of alkaloids, which will far surpass that which we have learned in the past 50 years. These tools will also be exploited for the rapid characterization of regulatory genes, which control the development of specialized cell factories for alkaloid biosynthesis.

Abstract
Recent advances in the cell, developmental, and molecular biology of alkaloid biosynthesis have heightened our appreciation for the complexity and importance of plant secondary pathways. Several biosynthetic genes involved in the formation of tropane, benzylisoquinoline, and terpenoid indole alkaloids have now been isolated. The early events of signal perception, the pathways of signal transduction, and the function of gene promoters have been studied in relation to the regulation of alkaloid metabolism. Enzymes involved in alkaloid biosynthesis are associated with diverse subcellular compartments including the cytosol, vacuole, tonoplast membrane, endoplasmic reticulum, chloroplast stroma, thylakoid membranes, and perhaps unique "biosynthetic" or transport vesicles. Localization studies have shown that sequential alkaloid biosynthetic enzymes can also occur in distinct cell types, suggesting the intercellular transport of pathway intermediates. Isolated genes have also been used to genetically alter the accumulation of specific alkaloids and other plant secondary metabolites. Metabolic modifications include increased indole alkaloid levels, altered tropane alkaloid accumulation, elevated serotonin synthesis, reduced indole glucosinolate production, redirected shikimate metabolism, and increased cell wall-bound tyramine formation. This review discusses the biochemistry, cell biology, molecular regulation, and metabolic engineering of alkaloid biosynthesis in plants.

Abstract
A comprehensive survey of the extensive literature relevant to the evolution, physiology, biochemistry, regulation, and genetic engineering applications of plant aromatic L-amino acid decarboxylases (AADCs) is presented. AADCs catalyze the pyridoxal-5'-phosphate (PLP)-dependent decarboxylation of select aromatic L-amino acids in plants, mammals, and insects. Two plant AADCs, L-tryptophan decarboxylase (TDC) and L-tyrosine decarboxylase (TYDC), have attracted considerable attention because of their role in the biosynthesis of pharmaceutically important monoterpenoid indole alkaloids and benzylisoquinoline alkaloids, respectively. Although plant and animal AADCs share extensive amino acid homology, the enzymes display striking differences in their substrate specificities. AADCs from mammals and insects accept a broad range of aromatic L-amino acids, whereas TDC and TYDC from plants exhibit exclusive substrate specificity for L-amino acids with either indole or phenol side chains, but not both. Recent biochemical and kinetic studies on animal AADCs support basic features of the classic AADC reaction mechanism. The catalytic mechanism involves the formation of a Schiff base between PLP and an invariable lysine residue, followed by a transaldimination reaction with an aromatic L-amino acid substrate. Both TDC and TYDC are primarily regulated at the transcriptional level by developmental and environmental factors. However, the putative post-translational regulation of TDC via the ubiquitin pathway, by an ATP-dependent proteolytic process, has also been suggested. Isolated TDC and TYDC genes have been used to genetically alter the regulation of secondary metabolic pathways derived from aromatic amino acids in several plant species. The metabolic modifications include increased serotonin levels, reduced indole glucosinolate levels, redirected shikimate metabolism, increased indole alkaloid levels, and increased cell wall-bound tyramine levels.
