Plant Evolutionary Genetics & Genomics
Our research investigates the genomics, and genetic engineering of crop plants for improved field traits and resistance to stress conditions. We are specifically interested in the evolutionary genetics of cotton fiber development which encompasses molecular and genome evolution, phylogenetics, and functional characterization of key gene families evolved under cotton domestication using transgenic technologies. We aim to analyse the temporal transcriptomes of wild and domesticated cotton species to identify novel targeted genes especially hormone signaling genes and cell-wall modifying genes; and characterize their molecular interactions with other signalling proteins and receptor kinases during cotton fiber development. Our research group also aims to analyse in vivo functions of Auxin Response Factors (ARFs) through target-mimicry based expression diminution of microRNA167 gene family by generating transgenic stocks for i) enhanced fiber elongation in cotton; and ii) improved silique elongation and drought tolerance in Indian mustard. Altered plant hormonal activities in root-to-shoot communication are being utilized in the development of transgenic mustard with enlarged root system and increased drought tolerance without having negative side effects on the aerial organs. Our goal is to apply these findings to sustainable agricultural practices that benefit society.
