Genetic diversity and relationship between Egyptian Vigna (Vigna spp. (L.) Walp.) taxa populations via Phenotypic and Molecular profiling

Genetic diversity is crucial for the conservation and improvement of plant populations. In this study, we used molecular and phenotypic profiling to determine the genetic diversity and relationships among Egyptian Vigna populations, including V. radiata, V. unguiculata, and V. luteola. The samples were profiled using amino acids and rbcL sequences, and the data were analyzed to determine the similarities among the taxa. The results showed a high degree of similarity between V. radiata and V. unguiculata, followed by V. luteola and V. unguiculata, and V. luteola and V. radiata. These taxa are closely related to V. unguiculata subsp. cylindrical and V. oblongifolia. Our findings suggest that molecular- and phenotypic-based profiling can help in prioritizing different disciplines based on assigning them to the proper taxonomic position through extra collections and management. These findings have practical implications for the management of Egyptian Vigna populations, as they can inform conservation and crop improvement efforts. Further research in this area could help preserve the wealth of germplasm for biodiversity and contribute to the sustainable use of plant resources.
