Identification of a Transport Mechanism for NH4+ in the Symbiosome Membrane of Pea Root Nodules.

abstract：:Cold acclimation and freezing tolerance are the result of complex interaction between low temperature, light, and photosystem II (PSII) excitation pressure. Previous results have shown that expression of the Wcs19 gene is correlated with PSII excitation pressure measured in vivo as the relative reduction state of PSII...
