Nitrogen (N) and potassium (K) are two most abundant essential nutrients for plant growth and development. Although ammonium (NH4+) is the predominant N form in anaerobic flooded paddy soil, rice and other wetland plants may take up significant amounts of nitrate (NO3-) formed by nitrification of NH4+ in the rhizosphere. Cellular pH homeostasis is fundamental for life and all cells adapt to maintain this balance. In plants the chemical form and amount of NO3- and NH4+ together with K+ dominate the preliminary change of cellular pH. My presentation will focus on the regulating nitrate and K+ transport for increasing rice yield and nutrient efficiency, providing an explanation for plant adaptation to changes in NH4+-NO3- supply shift between the waterlogged and drained soil environment.
The seminar will be delivered in English.
