My research endeavours over the last ten years have been focused on Molecular Microbiology, Microbial Physiology, and Genetics of environmental microbes. Molecular and functional analysis of phytohormone (indole acetic acid, IAA) biosynthesis in the plant associated bacteria, Azospirillum has broadened knowledge relating to regulation of this plant growth promoting trait and extended understanding of the role of these phytohormones in plant-microbe interactions and improving host plant productivity. The successful use of novel mutagenesis strategies for environmental bacteria has aided detailed analysis of different microbial genomes and variations exhibited by them.
