Plant take up the essential nutrient sulfur as sulfate from the soil, reduce it, and assimilate into bioorganic compounds, with cysteine being the first product. 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 progress 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.
植物从土壤中以硫酸盐的形式吸收必需的营养物质硫，将其还原，并将其同化到生物有机化合物中，半胱氨酸是第一个产物。硫酸盐的吸收和同化都受到还原硫需求、养分可用性和环境条件的高度调节。在过去的十年中，在解析硫代谢的调控方面取得了巨大的进展。硫酸盐的吸收和由 APS 还原酶将活性硫酸盐、腺苷 5'-磷酸硫酸盐（APS）还原为亚硫酸盐似乎是关键的调控步骤。在这里，我们回顾了这些过程的调控的最新知识，特别关注了它们的相似性和差异性。
