D11 — Cucumis melo

Summary

MELO3C021427.2 (CmD11) on melon chromosome 12 encodes a protein with a bZIP domain and a TGA domain, annotated with salicylic acid binding, calmodulin binding, disulfide oxidoreductase activity, and transcriptional co-regulator functions. The gene is associated with regulation of systemic acquired resistance, defence response to bacteria, salicylic acid anabolism, and response to photooxidative stress. It is linked to cold tolerance in melon and to numerous traits including bacterial blight disease resistance, cucurbit downy mildew response, drought sensitivity, plant male sterility, flower and petal development, bract morphology, seed set percent, and nitrogen sensitivity. The product localises to the nucleus, cytoplasm, plasmalemma, and mitochondria. Studies of related genes in other species connect this gene group to salicylic acid-mediated immune response, jasmonic acid response, and floral organ development.
