Plant Protein Signalling Networks

Signalling systems are essential to coordinate the correct expression of genes so multicellular organisms can grow and develop properly. However, plant signalling systems are poorly understood. We have demonstrated the presence and activity of an interesting novel and promising class of small proteins called: Plant Natriuretic Peptides (PNPs). PNPs are systemic protein hormones that modulate plant water balance and growth. Our aim is to characterise their function at molecular and cellular levels to elucidate their signalling interactions, particularly in response to drought and saline stresses. Importantly, this will lead to a better understanding of plant growth and how it is modified in response to drought and/or saline conditions.
