Sulfur is taken up by plants as the inorganic oxidized anion sulfate, which is assimilated into the variety of cellular metabolites.展开更多

Both sulfate uptake and assimilation are highly regulated by the demand for the reduced sulfur, by availability of nutrients, and by environmental conditions. In the last decade, great prog- ress has been achieved in dissecting the regulation of sulfur metabolism. Sulfate uptake and reduction of activated sulfate, adenosine 5＇-phosphosulfate （APS）, to sulfite by APS reductase appear to be the key regulatory steps. Here, we review the current knowledge on regulation of these processes, with special attention given to similarities and differences.展开更多
