Research interests:

Plants constantly modify their physiological processes in response to developmental and environmental cues. The reprogramming of cell differentiation in response to stimuli requires alteration of gene expressions, posttranscriptional and/or translational modifications of factors. Regulation of gene expression needs to occur in the context of chromatin. Change in chromatin landscape is therefore the rate-limiting step for such DNA-dependent processes.  The central question therefore is to understand how gene expression is precisely regulated to give rise to the spatio-temporal response.

Research:

  Investigating the role of ARID/HMG in modulation of chromatin structure in planta :  

This project involves the study of a novel class of high mobility group (HMG) protein ARID-HMG known to modulate the chromatin structure during nuclear events. ARID-HMG proteins contain both the AT rich interaction domain (ARID) and the HMG-box domain in a single polypeptide. Of four the Arabidopsis ARID-HMG proteins, biochemical characterisations have been undertaken for AtHMGB11 (At1g55650) and AtHMGB15 (At1g04880), to understand the functionality of this protein and its individual domains. Our results indicate that ARID-HMG can bind different DNA topological forms, can bend DNA backbone and can also induce DNA supercoiling; hence facilitating nuclear processes. The present work involves a detailed biochemical and functional characterisation of AtHMGB11 and AtHMGB15.

The project also encompasses the study of key interacting partners of AtHMGB15. Protein-protein interaction study (Yeast two-hybrid assay) has revealed a Zinc finger C3HC4 RING/U-Box superfamily protein to interact with AtHMGB15 protein. Presently we are characterising the significance of this interaction.

Understanding the epigenetic regulation involved in transcription of abiotic stress induced genes in rice. 

In this project we are investigating the epigenetic changes involved during the expression of stress responsive genes of rice. Abiotic stresses, such as, salinity and low temperature adversely affects the growth and development of plants. The study is also extended to a comparative epigenetic profiling in the context of rice plants for both sensitive and tolerant cultivars. Currently, a genome-wide study has been undertaken to identify changes in the epigenetic marks and co-relating it with the changes in the transcriptome when rice plants are subjected to different environmental stress.
