CHS4 — Brassica oleracea var. botrytis

Summary

BoCHS4 (CHS4) on chromosome 7 of cauliflower (Brassica oleracea var. botrytis) encodes an LSD1-like zinc-finger protein with S-nitrosylase activity and DNA-binding transcription factor activity. It is associated with positive regulation of seed maturation, macroautophagy, aerenchyma formation, photoperiodism, and responses to superoxide, oomycetes, and sulfate or nitrogen starvation. The gene has been linked to biomass yield, seed yield, water use efficiency, nitrate uptake, chlorophyll a and b content, chloroplast development, leaf senescence, disease tolerance, low temperature and salt stress responses, stomatal closure, and vegetative growth time. Related genes in other species are associated with programmed cell death, disease resistance, and cell death regulation.
