Research Interests:
Nengyi and Nick Lepak, field technician, are involved in the project of nitrogen use efficiency (NUE) in maize.
Nitrogen (N) is an essential nutrient to plant growth. Grain yields of maize and other important cereals are highly responsive to supplemental nitrogen. The use of N fertilizers has been dramatically increased during the last few decades. However, such high usage increases crop input costs, negatively impacts the quality of ground water with nitrates, and raises the energy requirement for crop production. Therefore, understanding genes controlling N uptake from soil, assimilation into amino acids, and N transport from vegetative sources to reproductive sink tissues will help develop varieties with improved NUE.
In this project, they are conducting enzyme activity assay related to nitrogen assimilation in the maize association panel and maize QTL mapping populations, analyzing enzyme activity QTLs (aQTL), identifying candidate genes for association with enzyme activities, nitrogen uptake and NUE, and evaluating nitrogen uptake in nested association mapping (NAM) populations (the world largest QTL mapping populations). The project aims to identify and characterize genomic regions and candidate genes for NUE.
This project is supported by a NSF grant, Gene Discovery for Maize Responses to Nitrogen, awarded to Drs. Stephen Moose, Edward Buckler and Frederick Below.
