ABSTRACT
Plant and rhizobacterial interactions contribute partly to a plant's medicinal properties and are well studied through metagenomics. In this study, 16S rDNA, 18S rDNA, and ITS meta-sequencing were performed using the genomic DNA obtained from the rhizosphere of Caesalpinia bonducella-a medicinal shrub widely used to treat polycystic ovary syndrome (PCOS). Of the 665 Operational Taxonomic Units (OTUs) obtained from 16S rDNA sequencing, 23.9% comprised of microbes that increase the therapeutic value of plants (Bacillus, Paenibacillus), 6.4% belonged to stress and drought tolerant microbes (Pseudomonas, Rhizobium, Serratia), 8% belonged to plant-growth promoting rhizobacteria-predominantly Proteobacteria, and Firmicutes and the remaining were the microbes performing various other functions. Alpha diversity indexing by GAIA-metagenomics tool revealed the presence of a highly diverse group of microbes in the rhizosphere of C. bonducella; Chao.1 index (665), Shannon Weiner index (3.53), Simpson index (0.83) and Fisher index (106.13). The highly diverse microbes lingering around the roots of C. bonducella could possibly be due to a strong symbiotic association with the plant; root exudates nourish the microbes and the microbes in turn enrich the medicinal value of the plant.
