| Research Abstract |
In this project, we tried to isolate rice stay-green genes NYC3, NYC4and FSG1. NYC3encoded a novel α/β hydrolase-fold family protein, which is thought to be an enzyme metabolizing chlorophyll. NYC4 was an ortholog of THYLAKOID FORMATION1 in Arabidopsis thaliana. Our analysis suggests that NYC4 plays an important role in degradation of photosystem II subunits. In addition, we successfully delimited the candidate region of FSG1within 200kb.
