 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, we have classified the process into five stages. Microarray performed on these stages shows 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. Thus, a plethora of genes involved in controlling rice seed development have emerged. We have also performed RNAseq on the five stages from two genotypes of rice with extremes of seed size/ weight, and have listed out genes/pathways controlling rice seed size. Apart from this, research is ongoing to functionally characterize genes which control the seed size and nutrition, with the aim of producing a better crop.
