Effect of Glucose and CO(2) on Nitrate Uptake and Coupled OH Flux in Ankistrodesmus braunii.

abstract：:Plant growth and development are strongly dependent on sink-source interactions. In the majority of plants, sucrose (Suc) is the dominant form in which photo-assimilate is transported from source to sinks. Although the effects of Suc on photosynthetic metabolism have been intensively studied, the effect of Suc supply ...
