CS1 — Brassica oleracea var. botrytis

Summary

BoCS1, located on cauliflower chromosome 8, encodes a haem peroxidase family protein with L-ascorbate peroxidase activity and additional annotated functions including p-coumarate 3-hydroxylase activity, kinase activity, and siRNA/miRNA binding. The gene is associated with diverse biological processes such as cellular response to oxidative stress, hydrogen peroxide catabolism, stomatal complex development, leaf patterning, cell cycle regulation, and auxin metabolism. It localises to multiple cellular compartments including the peroxisome membrane, chloroplast thylakoid membrane, plasmodesmata, and stress granules. BoCS1 is associated with agronomically important traits including drought tolerance, bacterial blight disease resistance, flowering time, seed viability, leaf senescence, root morphology, and salt tolerance. Studies of related genes in other species connect the family to heat stress tolerance, photoprotection, root development, and viral resistance.
