- Plant sulfation pathways are interconnected with sulfur metabolism.
- Synthesis of PAPS is essential for plant growth and development.
- New genes for plant sulfation pathways await discovery.
Plants take up sulfur in the form of sulfate. Sulfate is activated to adenosine 5â²-phosphosulfate (APS) and reduced to sulfite and then to sulfide when it is assimilated into amino acid cysteine. Alternatively, APS is phosphorylated to 3â²-phosphoadenosine 5â²-phosphosulfate (PAPS), and sulfate from PAPS is transferred onto diverse metabolites in its oxidized form. Traditionally, these pathways are referred to as primary and secondary sulfate metabolism, respectively. However, the synthesis of PAPS is essential for plants and even its reduced provision leads to dwarfism. Here the current knowledge of enzymes involved in sulfation pathways of plants will be summarized, the similarities and differences between different kingdoms will be highlighted, and major open questions in the research of plant sulfation will be formulated.
