摘要

代表五个种群的70种翼豆基因型，包括来自印度（IN）、泰国（TH）、尼日利亚（NI）、加纳（GH）和巴布亚新几内亚（PNG）的基因型。广泛接受的人口分析工具；，POPGene 1.3版、GenAlEx 6.5版、Splits Tree 4.15.1版、STRUCTURE 2.3.4版以及STRUCTURE Harvester 6.0版和MVSP 3.22版用于数据和解释。结果显示，泰国的种群多样性最高。种群之间的遗传多样性与地理无关。除PT-1外，所有印度样本归在一起，一个泰国样本（PT-33）与其他泰国样本完全不同，巴布亚新几内亚的PT-69与其他样本高度不同。聚类分析显示，四个泰国样本（PT-31、PT-32、PT-48和PT-49）、两个印度样本（PT-28和PT-29）和两个泰国样本，（PT-42和PT-46）在遗传上更接近，欧几里得距离较小，为0，而PT-39的最大距离为0.87。根据本研究，PT-33（EC 178272）、PT-、69（EC 38821 P2）和PT-39（EC 178 291）可被标记为遗传变异。

Population diversity analysis of an underutilized legume, winged bean (Psophocarpus tetragonolobus (L.) DC.) using ISSR markers

Seventy genotypes of winged bean representing five populations, include the, genotypes from India (IN), Thailand (TH), Nigeria (NI), Ghana (GH) and Papua New, Guinea (PNG) were taken for the study. Widely accepted population analysis tools;, POPGene Ver.1.32, GenAlEx Ver. 6.5, Splits Tree Ver.4.15.1, STRUCTURE Ver., 2.3.4 and Structure Harvester Ver.6.0 and MVSP Ver.3.22 were used for data, interpretation. Results revealed that the highest diversity was observed in Thailand, population. Genetic diversity between populations was not related to geography. All the, Indian samples except PT-1 grouped together, one Thailand sample (PT-33) was, totally different from other Thailand samples and PT-69 of PNG highly distinct from, other samples. Cluster analysis revealed that four Thailand samples (PT-31, PT-32, PT-48, and PT-49) two Indian samples (PT-28 and PT-29) and two Thailand samples, (PT-42 and PT-46) are genetically closer with less Euclidean distance of 0, whereas, PT-39 showed a maximum distance of 0.87. From this study, PT-33 (EC 178272), PT-, 69 (EC 38821 P2) and PT-39 (EC 178291) could be labelled as genetic variants.

期刊介绍： Plant Gene publishes papers that focus on the regulation, expression, function and evolution of genes in plants, algae and other photosynthesizing organisms (e.g., cyanobacteria), and plant-associated microorganisms. Plant Gene strives to be a diverse plant journal and topics in multiple fields will be considered for publication. Although not limited to the following, some general topics include: Gene discovery and characterization, Gene regulation in response to environmental stress (e.g., salinity, drought, etc.), Genetic effects of transposable elements, Genetic control of secondary metabolic pathways and metabolic enzymes. Herbal Medicine - regulation and medicinal properties of plant products, Plant hormonal signaling, Plant evolutionary genetics, molecular evolution, population genetics, and phylogenetics, Profiling of plant gene expression and genetic variation, Plant-microbe interactions (e.g., influence of endophytes on gene expression; horizontal gene transfer studies; etc.), Agricultural genetics - biotechnology and crop improvement.
