[PMID: 38493973 DOI: 10.1016/j.gene.2024.148385] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2023] [Revised: 03/11/2024] [Accepted: 03/14/2024] [Indexed: 03/19/2024]
Abstract
Juglans sigillata Dode is one of the important tree species in southwest China, and it has significant economic and ecological value. However, there is still a lack of effective methods to identify the functional genes of J. sigillata. By verifying the model plant tobacco, the pTRV2::JsPDS vector was able to cause photobleaching. This study showed that photobleaching occurred 24 and 30 d after the silencing vector was infected with aseptic seedlings and fruits of J. sigillata, respectively. When the OD600 was 0.6, and the injection dose was 500 μL, the gene silencing efficiency of aseptic seedlings was the highest at 16.7 %, significantly better than other treatments. Moreover, when the OD600 was 0.8, and the injection dose was 500 μL, the gene silencing efficiency in the walnut fruit was the highest (20 %). In addition, the VIGS system was successfully used to silence JsFLS2 and JsFLS4 genes in J. sigillata. This study also showed that the flavonol content and gene expression in the treatment group were decreased compared to the control group. In addition, the proteins transcribed and translated from the JsFLS4 gene may have higher catalytic activity for dihydroquercetin. The above results indicate that the TRV-mediated VIGS system can be an ideal tool for studying J. sigillata gene function.

Abstract
The use of gene-editing tools, such as zinc finger nucleases, TALEN, and CRISPR/Cas, allows for the modification of physiological, morphological, and other characteristics in a wide range of crops to mitigate the negative effects of stress caused by anthropogenic climate change or biotic stresses. Importantly, these tools have the potential to improve crop resilience and increase yields in response to challenging environmental conditions. This review provides an overview of gene-editing techniques used in plants, focusing on the cultivated tomatoes. Several dozen genes that have been successfully edited with the CRISPR/Cas system were selected for inclusion to illustrate the possibilities of this technology in improving fruit yield and quality, tolerance to pathogens, or responses to drought and soil salinity, among other factors. Examples are also given of how the domestication of wild species can be accelerated using CRISPR/Cas to generate new crops that are better adapted to the new climatic situation or suited to use in indoor agriculture.

Agroinfiltration-based transient genome editing for targeting phytoene desaturase gene in kinnow mandarin (C. reticulata Blanco). Mol Biotechnol 2023:10.1007/s12033-023-00980-z. [PMID: 38041775 DOI: 10.1007/s12033-023-00980-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2023] [Accepted: 11/01/2023] [Indexed: 12/03/2023]
Abstract
Citrus reticulata Blanco also known as kinnow mandarin is a widely grown horticultural crop in Punjab. CRISPR/Cas9 technology is being widely used for generation of varieties with increased resilience towards abiotic and biotic stresses as well as improved horticultural traits. Xanthomonas citri subsp. citri (Xcc)-mediated Agroinfiltration offers a fast and transgene-free method for the delivery of CRISPR/Cas9 constructs for systemic introduction into plants for functional genomics and expression studies. The technology is currently unexplored in kinnow mandarin. This study is aimed at establishing an efficient method of Cas9 delivery for transient knockout of PDS (phytoene desaturase) gene in kinnow mandarin. The construct pKO-119-PDS N-Cas9/sgRNA:PDS1 carrying sgRNA and Cas9 enzyme was delivered into the dorsal surface of young leaves of kinnow mandarin. The leaves showed albino patches at the point of injection within 60 h. Two surfactants (Triton-X and Silwet™) were used to ease the Agroinfiltration process which resulted in variation in the expression of vector. The Sanger's analysis of the treated plants showed a substitution within the sgRNA region which resulted in change in amino acid from proline to serine. The protocol provides a feasible and an efficient method for genome editing in C. reticulata which could be helpful in future studies aimed at genome editing as well as genetic transformation.

Abstract
Fagopyrum tataricum (L.) Gaertn. is an exceptional crop known for its remarkable health benefits, high levels of beneficial polyphenols and gluten-free properties, making it highly sought-after as a functional food. Its self-fertilisation capability and adaptability to challenging environments further contribute to its potential as a sustainable agricultural option. To harness its unique traits, genetic transformation in F. tataricum is crucial. In this study, we optimised the Agrobacterium-mediated transformation protocol for F. tataricum callus, resulting in a transformation rate of regenerated plants of approximately 20%. The protocol's effectiveness was confirmed through successful GUS staining, GFP expression, and the generation of albino plants via FtPDS gene inactivation. These results validate the feasibility of genetic manipulation and highlight the potential for trait enhancement in F. tataricum.

CRISPR/Cas9-mediated editing of phytoene desaturase ( PDS) gene in an important staple crop, potato. 3 Biotech 2023; 13:129.

Abstract
The gene editing using the CRISPR/Cas9 system has become an important biotechnological tool for studying gene function and improving crops. In this study, we have used CRISPR/Cas9 system for editing the phytoene desaturase gene (PDS) in popular Indian potato cultivar Kufri Chipsona-I. A construct (pHSE401) carrying two target gRNAs with glycine tRNA processing system under the control of Arabidopsis U6 promoter and the Cas9 protein was constructed and transformed in potato plants using Agrobacterium-mediated genetic transformations. The regeneration efficiency of 45% was observed in regenerated plants, out of which 81% of the putative transformants shoot lines exhibited mutant or bleached phenotype (albinism). The deletion mutations were detected within the StPDS gene in the genotyped plants and a mutation efficiency of 72% for gRNA1 and gRNA2 has been detected using Sanger sequencing. Hence, we set up a CRISPR/Cas9-mediated genome editing protocol which is efficient and generates mutations (deletions) within StPDS gene in potato. The bleached phenotype is easily detectable after only few weeks after Agrobacterium-mediated transformation. This is the first report as a proof of concept for CRISPR/Cas9-based editing of PDS gene in Indian potato cv. Kufri Chipsona-I. This study demonstrates that CRISPR/Cas9 can be used to edit genes at high frequency within the genome of the potato for various traits. Therefore, this study will aid in creating important mutants for modifying molecular mechanisms controlling traits of agronomic importance.

Abstract
Viral vectors hold enormous potential for genome editing in plants as transient delivery vehicles of CRISPR-Cas components. Here, we describe a protocol to assemble plant viral vectors for single-guide RNA (sgRNA) delivery. The obtained viral constructs are based on compact T-DNA binary vectors of the pLX series and are delivered into Cas9-expressing plants through agroinoculation. This approach allows rapidly assessing sgRNA design for plant genome targeting, as well as the recovery of progeny with heritable mutations at targeted loci. For complete details on the use and execution of this protocol, please refer to Uranga et al. (2021)1 and Aragonés et al. (2022).2.

Abstract
Vegetable crops provide a rich source of essential nutrients for humanity and represent critical economic values to global rural societies. However, genetic studies of vegetable crops have lagged behind major food crops, such as rice, wheat and maize, thereby limiting the application of molecular breeding. In the past decades, genome sequencing technologies have been increasingly applied in genetic studies and breeding of vegetables. In this review, we recapitulate recent progress on reference genome construction, population genomics and the exploitation of multi-omics datasets in vegetable crops. These advances have enabled an in-depth understanding of their domestication and evolution, and facilitated the genetic dissection of numerous agronomic traits, which jointly expedites the exploitation of state-of-the-art biotechnologies in vegetable breeding. We further provide perspectives of further directions for vegetable genomics and indicate how the ever-increasing omics data could accelerate genetic, biological studies and breeding in vegetable crops.

Abstract
The clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated (Cas) system provides a groundbreaking genetic technology that allows scientists to modify genes by targeting specific genomic sites. Due to the relative simplicity and versatility of the CRISPR/Cas system, it has been extensively applied in human genetic research as well as in agricultural applications, such as improving crops. Since the gene editing activity of the CRISPR/Cas system largely depends on the efficiency of introducing the system into cells or tissues, an efficient and specific delivery system is critical for applying CRISPR/Cas technology. However, there are still some hurdles remaining for the translatability of CRISPR/Cas system. In this review, we summarized the approaches used for the delivery of the CRISPR/Cas system in mammals, plants, and aquacultures. We further discussed the aspects of delivery that can be improved to elevate the potential for CRISPR/Cas translatability.
