Research directions: (1) Taking monocotyledonous model plant rice and dicotyledonous model plant Arabidopsis as research objects, carry out research on the molecular mechanism of plant absorption and utilization of trace elements iron (Fe), manganese (Mn), copper (Cu) and zinc (Zn). (2) Through screening and identifying local varieties of rice and upland rice rich in mineral nutrition, and using traditional breeding methods to cultivate rice and upland rice varieties with high and stable yield and rich in mineral nutrition, and using gene editing to directly target the key factors that absorb mineral nutrition to improve the mineral nutrition content of the current main varieties of rice and upland rice.
