Plant sulphur metabolism is stimulated by photorespiration.

ABSTRACT: Intense efforts have been devoted to describe the biochemical pathway of plant sulphur (S) assimilation from sulphate. However, essential information on metabolic regulation of S assimilation is still lacking, such as possible interactions between S assimilation, photosynthesis and photorespiration. In particular, does S assimilation scale with photosynthesis thus ensuring sufficient S provision for amino acids synthesis? This lack of knowledge is problematic because optimization of photosynthesis is a common target of crop breeding and furthermore, photosynthesis is stimulated by the inexorable increase in atmospheric CO₂. Here, we used high-resolution ³³S and ¹³C tracing technology with NMR and LC-MS to access direct measurement of metabolic fluxes in S a
