HSP70 — Brassica oleracea var. botrytis

Summary

BoHSP70, located on chromosome 3 of cauliflower (Brassica oleracea var. botrytis), encodes a member of the heat shock protein 70 family, characterized by an ATPase domain and chaperone activity. The gene product exhibits DXP-synthase activity, binds salicylic acid, and is annotated as a protein-folding chaperone. BoHSP70 is associated with diverse biological processes including the response to chlorate, cellular response to salicylate stimulus, RuBisCO assembly, the MEP pathway, homologous recombination, and the upregulation of defense response to oomycetes. It is linked to numerous agronomic traits such as biomass yield, photosynthetic ability and rate, plant height, drought tolerance, disease tolerance, leaf necrosis, and responses to high and low temperature stress. The gene is also connected to phenotypes including salt and chilling tolerance, immune response, disease resistance, and salicylic acid signaling.
