Research interests: 

The major thrust of the lab is to understand the complicated regulatory networks operative in higher organisms. These networks can be visualized as multi-dimensional systems composed of various genomic elements (proteins, regulatory RNAs, cis-acting elements etc) that interact with each other in response to various developmental and environmental cues. MicroRNAs define one such dimension. They are known to regulate a wide variety of developmental and metabolic processes in both plants and animals. One of the research objectives is to identify novel miRNAs and their interacting partners in plants. In order to gather a comprehensive perspective ‘Deep sequencing' followed by bioinformatics analysis of the entire small RNA population from various tissue and developmental stages of rice is being done. Thus, it would be possible to characterize global changes in the microRNAs population under various developmental and environmental conditions. 
On the other hand, work has also been initiated to conceive logistics for manual literature-based curation of all the rice proteins with a view to develop a protein-centric interaction database of rice. Instead of a simple data compilation, the database would attempt to logically interconnect the various genomic elements on the basis of published information. The ultimate aim is to develop a self-perpetuating database that would act as a hub of information for researchers world-over and also enable research groups to actively share their findings through the database.
