Research Interests

We are interested in understanding the molecular mechanism by which far-red light regulates gene expression in plants. Our research is focussed on phytochromes and elucidating downstream signalling networks in plants. We investigate how plants use the phytochromes and other photoreceptors to respond the vegetation proximity and the signalling cascades that translate this information into adaptive responses.

Research Summary

Plants monitor and respond developmentally to an array of environmental light signals. Our research is aimed to understand light signal transduction pathways activated by the phytochrome family of sensory photoreceptors that absorb red and far-red region of the light spectrum. The photoreceptor molecule acts as a biological switch that upon perception of the light signal triggers rapid transcriptional changes. The transcriptional networks are comprised of a broad range of transcription factors and cofactors including Phy Interacting Factors (PIFs) that controls every aspect of the plant life cycle such as seed germination, de-etiolation and flowering time. Our research will help to understand how plants communicate to each other and neighbours especially using reflected light. This knowledge will important to realign our agricultural systems to be more efficient and productive in sustainable manner.
