ARQ1 — Brassica oleracea var. botrytis

Summary

BoARQ1, located on chromosome 7 of cauliflower (Brassica oleracea var. botrytis), encodes a protein with arsenate reductase (glutaredoxin) activity, belonging to the STR17/STR18/HARC1-like family and containing a rhodanese-like domain. The gene is associated with the detoxification of arsenic and the response to arsenic, and its product localises to both the cytoplasm and nucleus. Studies of related genes in other species link the family to arsenic concentration and to an arsenate-intolerant phenotype with poor root recovery, as well as to callus induction.
