APS2 — Brassica oleracea var. botrytis

Summary

BoAPS2 (APS2) on cauliflower chromosome 5 encodes a sulphate adenylyltransferase and also carries domains associated with cellulase activity and sugar binding. The gene is directly annotated to ATP:sulfate adenylyltransferase activity, cellulase activity, and sugar binding, and is associated with the biological processes of sulphate assimilation, cellular response to sulphate starvation, cellulose breakdown, cell growth, cell wall organization, and fruit ripening. It localises to the chloroplast stroma, membrane, nucleus, and extracellular space. Associations observed for the ASA1 variant include auxin and tryptophan biosynthesis, root regeneration, adventitious and lateral root formation, primary root elongation, PIN2 endocytosis, and phytoalexin biosynthesis. Studies of related genes in other species link the family to de novo root organogenesis, ATP sulfurylase activity, sulfur nutrition response, and defense response.
