Bioprospecting genes from higher altitude microbes/plants. Extreme climatic conditions and topography of higher altitude affect both microbes and plants. In particular, we are interested in higher altitude microbes/plants functional genomics with the major focus on enzymes of industrial relevance. Currently, we are targeting therapeutic proteins and industrially relevant enzymes from higher altitude microbes. Our strategy includes multi-dimensional approaches such as whole genome sequencing, proteomics, genetics, and bioinformatics to develop a bioprocess for the industrial use.


Small RNA-mediated gene regulation in bacteria. Small RNA regulators in bacteria are groups of small non-coding RNAs (sRNAs) ranging from 50 to 500 nts that are involved in gene regulation at the post-transcriptional level. sRNAs function to adjust bacterial physiology in response to different environmental cues. Therefore, we are interested in studying the role of sRNAs in understanding adaptation of higher altitude microbes in response to growth, stress, and changes in environmental conditions.
