APS2 — Brassica oleracea var. botrytis

Summary

BoAPS2 (APS2) on chromosome 8 of cauliflower encodes a sulphate adenylyltransferase, an enzyme with ATP:sulfate adenylyltransferase activity. The protein localises to the chloroplast stroma and nucleus. In this species, the gene is associated with sulphate assimilation, the cellular response to sulphate starvation, and cell growth. It is associated with adventitious root formation, auxin biosynthesis, root regeneration, tryptophan biosynthesis, PIN2 endocytosis, phytoalexin biosynthesis, primary root elongation, lateral root formation, and root growth. Studies of related genes in other species link the family to de novo root organogenesis, ATP sulfurylase activity, sulfur nutrition responses, defence responses, and camalexin biosynthesis.
