 Research Interests and ongoing work
Rice is the staple food of more than 50% of the world's population. The edible part is the seed or grain. Based on the morphological changes occurring during rice seed development, it can be classified into five stages. Microarray has been performed on these stages and compared with vegetative controls. Further, the microarray data has been validated by Q-PCR and by promoter-reporter constructs. Detailed analysis of microarray data showed that transcription factors form one of the major classes of differentially expressed genes. With this in view, many transcription factor encoding gene families such as the C2H2 zinc finger encoding gene family members have been identified from the rice genome. In silico analysis on these includes phylogeny, gene structure, protein domain and expression analysis. Transgenic rice plants have also been raised for genes showing high expression in the seed. Thus, a plethora of genes involved in controlling rice seed development have emerged. Members of many more such families seem to be playing important roles in rice seed development. Ongoing work includes delving deeper into the molecular biology of rice seed development and establishment of operating networks.
