Project/Area Number 21688006
Research Category

Grant-in-Aid for Young Scientists (A)

Allocation TypeSingle-year Grants
Research Field Plant nutrition/Soil science
Research InstitutionTohoku University

Principal Investigator

KOJIMA Soichi  東北大学, 大学院・農学研究科, 助教 (30462683)

Project Period (FY) 2009 – 2011

Research Abstract

Localized ammonium supply to Arabidopsis root increased root branching. The response was highly dependent on high-affinity ammonium transporter located at plasma membrane. This new knowledge may lead to improve nitrogen use efficiency in plant.
