摘要

Abrus precatorius L. (A. precatorius L.) holds significance as an essential medicinal plant renowned for its pharmacological properties and plays a crucial role in our ancient healthcare system. The genetic diversity of such a significant plant has not been studied previously in Gujarat, India. Therefore, the present study aimed to comprehend the genetic variations in A. precatorius L. for the first time across six different regions of Gujarat, India. The investigation employs 16 ISSR (Inter Simple Sequence Repeats) markers, to allow the detection of polymorphic loci, which helps to assess the genetic diversity in the selected regions. Moreover, the incorporation of a Geographical Information System aids in spatial data analysis as well as a DNA barcoding technique to efficiently validate the identity of the sample and distinguish closely related species. The assessment resulted in a substantial 83.97% polymorphism among the A. precatorius L. of the Gujarat regions. The estimation of Polymorphic Information Content yielded a value of 0.27, indicating genetic variation within the regions. Based on Jaccard’s similarity coefficient, an Unweighted Pair Group Method with Arithmetic Mean (UPGMA) yielding cophenetic correlation coefficients of 0.84 and Neighbor-Joining dendrograms were constructed. The dendrograms revealed the genetic relatedness and diversity among the selected regions in Gujarat. Accession from the Ahmedabad region stood out most diverse of all the regions whereas accession from the Junagadh region remains the most primitive. These results can serve as a foundation for further research and conservation strategies to preserve the genetic diversity of A. precatorius L. and other medicinal plants in the region.
