Elucidating the regulatory mechanism of adjustment of growth and central metabolism in rice for efficient CO2 recycling under nitrogen-limiting conditions

 Carbon (C) and nitrogen (N) status in plants affects their growth and development. It is well recognized that cellular C and N metabolism in plants are tightly coordinated at different levels. For instance, N-limiting conditions inhibit plant growth; however, detailed mechanisms remain unclear. Aim of the study is to understand how plants coordinate cellular C and N balance via central metabolism, which is common and important in various organisms. The obtained insights will be immediately applied for developing breeding technologies of new cultivars which can grow healthy under nitrogen-limiting conditions.
