RPS2 — Brassica oleracea

Summary

BoRPS2, located on cabbage chromosome 1, encodes a protein with NB-ARC and LRR domains characteristic of plant NBS-LRR immune receptors, alongside AAA+ ATPase and P-loop NTPase domains. The gene is associated with diverse molecular functions including cation-transporting ATPase activity, peptide and salicylic acid binding, and blue light photoreceptor activity. It is linked to biological processes such as detection of bacteria, defense responses to insects and oomycetes, glucosinolate breakdown, jasmonic acid anabolism, and negative regulation of hypersensitive response. Associations with agronomically relevant traits include bacterial blight disease resistance, biomass yield, photosynthetic rate, water use efficiency, cadmium content, root weight, days to flowering, and self-incompatibility. The gene is also associated with phenotypes involving zinc homeostasis, cadmium detoxification, drought stress response, and pollen development.
