Abstract

Plant-microbe interaction forms the intrinsic part  of our ecosystem. This interaction is responsible  for remediating contaminants, sequestration of  carbon, plant disease control and plant growth  promotion. Phytoremediation capabilities can be  determined by thriving microbial communities  and variation in their species composition. The  composition of soil microbiome is affected by  various factors such as environment, climate and  plant genotype. In the present study, we have  assessed the seasonal variation in the bacterial  community structure in the rhizospheric  microbiome of weedy plants, Acorus calamus,  Typha latifolia, and Phragmites karka using T-RFLP.  The bacterial phyla dominating the summer  season belonged to Proteobacteria, Bacteriodetes,  Firmicutes were seen to abundant in P.karka followed by A.calamus and T.latifolia. During the  winter season the bacterial phyla that dominated  belonged to the phylum Bacetriodetes,  Proteobacteria, Firmicutes were found abundant in  P. karka followed by A. calamus and T. latifolia.  Diversity indices of the bacterial community  were assessed. The result of this study shows the  presence of seasonal variation in bacterial phyla  which can act as the potential candidates for the  remediation process.
