DND1 — Brassica oleracea var. botrytis

Summary

BoDND1, the cauliflower gene on chromosome 9, encodes a cyclic nucleotide-gated channel (CNGC) protein containing ion transport and cyclic nucleotide-binding domains, with molecular function as an intracellular cAMP-activated cation channel. The gene is associated with calcium ion import, macroautophagy, protein secretion, lignin anabolism, arbuscular mycorrhizae formation, hypersensitive response cell death, innate immunity, and defense response. It has been connected to vegetative phase change, pollen germination, thermotolerance, gravitropism, auxin signaling and homeostasis, senescence, flowering time, leaf senescence, seed production, brassinosteroid signaling, and extracellular ATP signal transduction. Related genes in other species link the family to ion transport, disease resistance, heat tolerance, programmed cell death, jasmonic acid signaling, floral transition, and calmodulin binding.
