“…In a recent study using fluorescent-labelled RAPD markers, six accessions of S. asoca revealed high degree (92.7%) of polymorphism (Mohan et al 2017). In another study, AMOVA revealed a 43% variation within the populations and 57% variation among the populations of S. asoca using inter simple sequence repeat (ISSR) markers (Hegde et al 2018a). The results of the PCoA undertaken in the current study showed that the three populations SAD, SAR and SADU formed a distinct group and were genetically closer than the other populations.…”

“…A clear understanding of population structure in a forest is essential to understand genetic diversity and to regularly assess the impact of protection strategies (Deshpande et al 2001;Ezzat et al 2016;Das et al 2017). Wild germplasm characterisation, particularly in an endangered plant species, provides baseline data to develop management strategies not only for protection and conservation but also for sustainable utilisation (Dawson and Powell 1999;Hegde et al 2018a). Conservation and preservation of rare plants require accurate assessment of their genetic diversity through objective indices and parameters (Nongrum et al 2012;Iranjo et al 2016).…”

Background: Saraca asoca (Roxb.) De Wilde is a valuable tree used in traditional medicine against a variety of ailments. Almost all parts of the tree are used for various commercial herbal preparations. Due to overexploitation, the species is rapidly disappearing from Western Ghats where it is native and grew extensively until recently. Conservation of this important medicinal plant is therefore an urgent need. To plan effective conservation strategies, a scientific assessment of the genetic diversity and distribution is needed. Methods: Random Amplified Polymorphic DNA fingerprinting was employed and the population genetic structure of seven wild and three cultivated populations totalling 160 individuals of S. asoca in the Western Ghats region of Karnataka, Maharashtra and Goa for analysis. Results: Variation of 89% was observed within populations while 11% was observed among the populations of S. asoca. Gene flow (Nm) of 2.01 was observed, and 0.19 was the degree of genetic differentiation recorded. Unweighted Pair Group Method with Arithmetic average (UPGMA) cluster analysis generated a dendrogram that showed an admixture of all genotypes but with two major clusters, which was also supported by a STRUCTURE-based Bayesian model. One wild population was well, but inexplicably, differentiated from the rest. Conclusions: The study shows that there is still considerable genetic diversity existing in natural populations of S. asoca, suggesting good natural cross-pollination, giving encouraging indications that the gene pool is under no immediate threat. Any conservation strategy should utilise the observed genetic variation in the choice of planting stock for programmes of conservation, propagation and reforestation.

The data presented in this article is in support of the research paper “Genetic and phytochemical investigations for understanding population variability of the medicinally important tree Saraca asoca to help develop conservation strategies” Hegde et al., 2018. This article provides PCR based Inter-Simple Sequence Repeat (ISSR) and HPLC datasets of 106 individual samples of Saraca asoca collected from various geographical ranges of the Western Ghats of India. The ISSR data includes information on genetic diversity and images of population structures generated through amplified DNA products from samples of Saraca asoca leaf. Phytochemical data obtained from HPLC includes concentration (mg/g) of gallic acid (GA), catechin (CAT), and epicatechin (EPI). The data also presents information obtained from various statistical analysis viz. standard error of the mean values, distribution variables, prediction accuracy, and multiple logistic regression analysis.

“…Genetic studies pronounced in S. asoca were specifically limited to resolving identification troubles in crude pills (Urumarudappa et al, 2016;Hegde et al, 2018). However, genetic markers had been used in different research 161 works to evaluate versions, relationships and population genetic parameters in S. asoca (Sumangala et al, 2016).…”

Saraca asoca is a relatively traded IUCN crimson listed tree species used in Ayurvedic drug treatments for the treatment of numerous disorders, especially gynecological troubles. However, information approximately the genetic variations among populations and corresponding variation in specialized metabolites of S. asoca stays uncertain. The presence of various antioxidant compounds including ascorbic acid, catechin, flavonoids, lignin glycosides, beta-sitosterol and its glucosidic identified in S. asoca leaf, bark and flower. The present study will provide basic information about distribution of Saraca asoca genotypes in India. Molecular characterization of Saraca asoca using molecular markers will be useful in the identification of diverse genotypes available in the country. Diverse genotypes and highly therapeutic compound may be used for future conservation and improvement program of Saraca asoca. Study has potential scope in the management of Saraca asoca species.
