Abstract
Sulfur is an essential nutrient for all organisms. Plants are able to take up inorganic sulfate and assimilate it into a range of bio-organic molecules either after reduction to sulfide or activation to 3′-phosphoadenosine 5′-phosphosulfate. While the regulation of the reductive part of sulfate assimilation and the synthesis of cysteine has been studied extensively in the past three decades, much less attention has been paid to the control of synthesis of sulfated compounds. Only recently the genes and enzymes activating sulfate and transferring it onto suitable acceptors have been investigated in detail with emphasis on understanding the diversity of the sulfotransferase gene family and the control of partitioning of sulfur between the two branches of sulfate assimilation. Here, the recent progress in our understanding of these processes will be summarized.
Highlights
Sulfur is essential for life as a component of proteins in the amino acids cysteine and methionine, a large number of co-enzymes and prosthetic groups as well as in many natural products of the secondary metabolism (Takahashi et al, 2011)
Analysis of apk3 fou8 double mutants, www.frontiersin.org in which the only cytosolic adenosine -phosphosulfate (APS) kinase was disrupted, revealed that it is not the phosphoadenosine -phosphosulfate (PAPS) transport causing the low glucosinolate phenotype, as their levels were identical to fou8 plants
Since in the desulfo-glucosinolate accumulating fou8 mutant the glucosinolate synthesis genes are not affected to the same degree as in apk1 apk2, it seems that Arabidopsis plants possess a mechanism reacting to low levels of one or more glucosinolates as a signal for induction of their synthesis
Summary
Sulfur is essential for life as a component of proteins in the amino acids cysteine and methionine, a large number of co-enzymes and prosthetic groups as well as in many natural products of the secondary metabolism (Takahashi et al, 2011). The partitioning of sulfur into the primary (reductive) and secondary (sulfated) assimilation represents an important step controlling the availability of this nutrient for synthesis of numerous compounds and has been addressed only very recently (Mugford et al, 2009, 2011).
