Translation mechanisms contributing to plant development and drought stress adaptation

Drought stress tolerance is multigenic in nature. Protein synthesis is affected under drought stress, which, in turn, influences cellular metabolic activities required for optimum functioning. 

Ribosomes are responsible for protein synthesis. However, ribosome biogenesis is a highly orchestrated mechanism involving many proteins for the translation activity of cells. We want to unravel how translational mechanisms regulate the adaptation abilities of plants under changing environmental conditions.

Areas of interest

Protein translational mechanisms in plants.
Extra-ribosomal functions of ribosomal proteins.
Ribosome biogenesis factors in plant growth and development.
Regulatory proteins of ribosome biogenesis.
Drought stress adaptation of plants.

My research focuses on understanding the basis of plant adaptation to drought to improve the productivity of our crops. Under stress conditions, the acquired tolerant traits play a crucial role as a measure of cellular level tolerance. Emphasis is on Ribosomal RNA (rRNA) processing mechanisms, ribosome biogenesis and their assembly factors.

Functional characterisation of the genes involved in these mechanisms and exploring their extra-ribosomal functions and relevance in growth, development and abiotic stress tolerance. Further, we want to unravel how translational regulation contributes to acclimation processes in changing climatic conditions. 

Identifying the relevant cis-elements on ribosomal RNA genes and ribosomal proteins encoding gene promoters and transcription factors involved in their expression and regulation of translational activity has phenomenal significance.

We are also working on developing strategies to improve resistance against bacterial leaf blight disease in rice-causing pathogen Xanthomonas oryzae pv oryzae. We use functional and chemical genomic approaches to improve plant health.
