Abstract
Justicia procumbens L. is a traditional medicinal plant that is widely distributed in China. However, little is known about the genetic diversity and evolution of this genus, and no genomic studies have been carried out on J. procumbens previously. In this study, we aimed to assemble and annotate the first complete chloroplast genome (cpDNA) of J. procumbens and compare it with all previously published cpDNAs within the tribe Justicieae. Genome structure and comparative and phylogenetic analyses were performed. The 150,454 bp-long J. procumbens cpDNA has a circular and quadripartite structure consisting of a large single copy, a small single copy, and two inverted repeat regions. It contains 133 genes, of which 88 are protein-coding genes, 37 are tRNA genes, and eight are rRNA genes. Twenty-four simple sequence repeats (SSRs) and 81 repeat sequences were identified. Comparative analyses with other Justicieae species revealed that the non-coding regions of J. procumbens cpDNA showed greater variation than did the coding regions. Moreover, phylogenetic analysis based on 14 cpDNA sequences from Justicieae species showed that J. procumbens and J. flava were most closely related. This study provides valuable genetic information to support further research on the genetic diversity and evolutionary development of the tribe Justicieae.

Kurt S, Kaymaz Y, Ateş D, Tanyolaç MB. Complete chloroplast genome of Lens lamottei reveals intraspecies variation among with Lens culinaris. Sci Rep 2023; 13:14959. [PMID: 37696838 PMCID: PMC10495401 DOI: 10.1038/s41598-023-41287-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/28/2023] [Accepted: 08/24/2023] [Indexed: 09/13/2023] Open
Abstract
Lens lamottei is a member of the Fabaceae family and the second gene pool of the genus Lens. The environmental factors that drove the divergence among wild and cultivated species have been studied extensively. Recent research has focused on genomic signatures associated with various phenotypes with the acceleration of next-generation techniques in molecular profiling. Therefore, in this study, we provide the complete sequence of the chloroplast genome sequence in the wild Lens species L. lamottei with a deep coverage of 713 × next-generation sequencing (NGS) data for the first time. Compared to the cultivated species, Lens culinaris, we identified synonymous, and nonsynonymous changes in the protein-coding regions of the genes ndhB, ndhF, ndhH, petA, rpoA, rpoC2, rps3, and ycf2 in L. lamottei. Phylogenetic analysis of chloroplast genomes of various plants under Leguminosae revealed that L. lamottei and L. culinaris are closest to one another than to other species. The complete chloroplast genome of L. lamottei also allowed us to reanalyze previously published transcriptomic data, which showed high levels of gene expression for ATP-synthase, rubisco, and photosystem genes. Overall, this study provides a deeper insight into the diversity of Lens species and the agricultural importance of these plants through their chloroplast genomes.

FRONTIERS IN PLANT SCIENCE 2023; 14:1127239. [PMID: 36998696 PMCID: PMC10044020 DOI: 10.3389/fpls.2023.1127239] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/19/2022] [Accepted: 02/22/2023] [Indexed: 05/31/2023]
Abstract
Crop wild relatives (CWRs), landraces and exotic germplasm are important sources of genetic variability, alien alleles, and useful crop traits that can help mitigate a plethora of abiotic and biotic stresses and crop yield reduction arising due to global climatic changes. In the pulse crop genus Lens, the cultivated varieties have a narrow genetic base due to recurrent selections, genetic bottleneck and linkage drag. The collection and characterization of wild Lens germplasm resources have offered new avenues for the genetic improvement and development of stress-tolerant, climate-resilient lentil varieties with sustainable yield gains to meet future food and nutritional requirements. Most of the lentil breeding traits such as high-yield, adaptation to abiotic stresses and resistance to diseases are quantitative and require the identification of quantitative trait loci (QTLs) for marker assisted selection and breeding. Advances in genetic diversity studies, genome mapping and advanced high-throughput sequencing technologies have helped identify many stress-responsive adaptive genes, quantitative trait loci (QTLs) and other useful crop traits in the CWRs. The recent integration of genomics technologies with plant breeding has resulted in the generation of dense genomic linkage maps, massive global genotyping, large transcriptomic datasets, single nucleotide polymorphisms (SNPs), expressed sequence tags (ESTs) that have advanced lentil genomic research substantially and allowed for the identification of QTLs for marker-assisted selection (MAS) and breeding. Assembly of lentil and its wild species genomes (~4Gbp) opens up newer possibilities for understanding genomic architecture and evolution of this important legume crop. This review highlights the recent strides in the characterization of wild genetic resources for useful alleles, development of high-density genetic maps, high-resolution QTL mapping, genome-wide studies, MAS, genomic selections, new databases and genome assemblies in traditionally bred genus Lens for future crop improvement amidst the impending global climate change.
