DESCRIPTION:Sulfate is a plant macronutrient with strong impact on stress 
 resistance and growth. The various oxidation states of sulfur carry out a 
 large number of essential functions in cells. These include protein struct
 ure and regulation\, electron transport\, redox control and primary and se
 condary metabolites that operate in catalysis\, detoxification or defense.
  Sulfate uptake\, reductive assimilation and channeling into downstream me
 tabolism need to be adjusted according to nutritional status\, development
 al  stage and stress conditions. The responses to demand and supply are co
 ordinated at the cellular and whole plant levels and include transcription
 al and metabolic control mechanisms as part of a network of primary metabo
 lic pathways. In particular\, the fine-tuning of cellular sulfur status de
 pends on a novel sensing system that is based on reversible dissociation o
 f a multiprotein complex in response to fluctuating metabolite levels. Sin
 ce cysteine and glutathione synthesis take place in plastids and the cytos
 ol\, intracellular communication forms an additional level of control with
  respect to sulfur and redox homeostasis.\n\nhttp://www.bot.uni-heidelberg
