ESP — Brassica oleracea var. botrytis

Summary

BoESP, encoded by the gene BOLND125_C07P028040.1 on cauliflower chromosome 7, is a protein with a Kelch-type β-propeller domain that exhibits lyase activity, fatty-acyl-CoA binding, and DNA-binding transcription factor activity specific to RNA polymerase II. It is associated with glucosinolate metabolism and breakdown, nitrile biosynthetic processes, thiocyanate metabolism, and the regulation of defense responses, including responses to jasmonic acid, salicylic acid, ozone, hydrogen peroxide, and bacteria. The gene has been linked to traits such as 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.
