 Research Interest
Water-deficit stress and regulation of nutrient (Pi) utilization
Water-deficit (WD) stress is a major constraint for modern agriculture as it results in reduced crop productivity. In addition to many physiological changes in plants, WD also reduces nutrient uptake from soil. This reduction in nutrient uptake is more in rice as compared to other crops at same reduced soil moisture status. Phosphate (Pi) is one of the most abundant nutrient ions in soil; however, it poses severe problems due to its unavailability to plants which is further enhanced in WD condition. Among the plant's adaptation tactics against Pi starvation, root system architecture modification is common with WD stress. We are interested in delineating the molecular mechanisms of root modification for improving Pi utilization under WD in rice.
