ESP — Brassica oleracea var. botrytis

Summary

BoESP, encoded by the gene BOLND125_C06P017580.1 on chromosome 6 of cauliflower (Brassica oleracea var. botrytis), is a protein with a Kelch-type β-propeller domain that exhibits lyase activity, DNA-binding transcription factor activity, fatty-acyl-CoA binding, and protein homodimerization activity. It is associated with glucosinolate metabolism and breakdown, nitrile biosynthetic processes, thiocyanate metabolism, and the regulation of defense responses, jasmonic acid-mediated signaling, and responses to ozone, hydrogen peroxide, salicylate, and bacteria. The gene is linked to traits including leaf and stem senescence, chlorophyll content, flowering time, drought tolerance, disease tolerance, stomatal resistance, and jasmonic acid content. Studies of related genes in other species connect the family to glucosinolate hydrolysis to nitriles, herbivory resistance, and salicylic acid response.
