 Research Interest

The remarkable feature of a multicellular organism is their ability to coordinate the information from different cells and tissues into one functional unit known as an organ. Plants develop different strategies to cope up with different environmental conditions throughout their life span. For example during low phosphate (Pi) availability, the model plant Arabidopsis reprograms its root system architecture in such a way (increased lateral roots and root hair density) that it can absorb more phosphate (Pi) from the soil for better survival. The cross talk of environmental signals to the developmental signals such as growth hormones in plants is a complex process. The coordination of these environmental and hormonal cues during the growth process is still a big question to be addressed. Despite a lot of studies in understanding the abiotic stresses such as drought, cold, heat and nutrient signaling in plants, our knowledge about how these environmental signals coordinate with the hormonal signals to maintain the growth is still scant.

We are interested in exploring and develop better understanding of context specific developmental plasticity of root system architecture under the limiting environmental conditions such as nitrogen and iron availability and their interaction with the developmental signals (growth promoting hormones such as auxin and steroid hormone, brassinosteroid) in Arabidopsis and tomato. It will enhance our knowledge to understand the growth processes under adverse environmental conditions and will be helpful in developing the plants with better productivity under limiting nutrient availability. To address the above objectives we will use advanced molecular and development biology tools and techniques such as live cell imaging, tissue specific translatome and proteome, yeast two hybrid system, CRISPR/Cas9 system of genome editing etc.
