Mesophyll conductance, photoprotective process and optimal N partitioning are essential to the maintenance of photosynthesis at N deficient condition in a wheat yellow-green mutant (Triticum aestivum L.).

Abstract excerpt

The major effect of nitrogen (N) deficiency is the inhibition on CO2 assimilation regulated by light energy absorption, transport and conversion, as well as N allocation. In this study, a yellow-green wheat mutant (Jimai5265yg) and its wild type (Jimai5265, WT) were compared between 0 mM N (N0) and 14 mM N (N14) treatments using hydroponic experiments. The mutant exhibited higher photosynthetic efficiency (An)...
