Title: Toward sustainable Green Revolution

Speaker: Prof. Xiangdong Fu, Institute of Genetics and Developmental Biology, CAS

Time: 9:30 am

Day/Date: April 1^st, 2021 (Thursday)

Host: Prof. Chao-Feng Huang

Venue: PSC Auditorium

The agricultural green revolution of the 1960s boosted crop yields is due to widespread adoption of semi-dwarf plant varieties, many of which are later found to have mutations in gibberellin (GA) homeostasis or signaling pathway. The green revolution semi-dwarf varieties (GRVs) exhibit increased harvest index and reduced risk of lodging, whereas GRVs require a large amount of N fertilizer inputs to achieve high yield. In my talk, I will present new approaches that explore rice nitrogen-use efficiency (NUE) within an overall plant systems biology context that considers the coordination between plant growth and metabolism as a whole organism in response to changes in N availability, and advances in understanding the molecular mechanisms underlying the N-responsive GA signaling and plant growth-metabolic coordination, and provides novel crop breeding strategies for improved grain yield and NUE in high-yield GRVs for future sustainable agriculture.
