Abstract
There are little information about the effect of nitrogen nutrition on the photosynthetic proteins after full expansion to senescence. The purpose of this study is to examine how the supply of nitrogen after full expansion influences major photosynthetic proteins in the 8th leaves of rice. Rice plants were grown under different levels of nitrogen (1 mM N and 4 mM N) at the stage of full expansion of the 8th leaves or at the 7th day after full expansion. In spite of the treatments, the ratio of Rubisco-N to total leaf N contents was greater in the leaves with 4 mM N. However, the respective ratios of LHCII, CF1 and Chl to total leaf N contents were little different between them. Thus, Rubisco was more largely affected by the N supply even after the stage of full expansion in rice.
