KC1 — Oryza sativa Japonica

Summary

OsKC1 (OS06G0254200) on rice chromosome 6 encodes a voltage-sensitive potassium channel with Kir channel activity and identical protein binding capability, belonging to the KAT/AKT and KHA domain families. This gene is associated with potassium uptake, stomatal closure and movement, seed germination, pollen tube growth, and response to salt stress. It has been linked to agronomically important traits including grain yield, grain weight, plant height, panicle length, root length, spikelet sterility, anthocyanin content, calcium concentration, and both salinity and drought tolerance. The encoded protein localizes to the monoatomic ion channel complex and ER membrane, and is associated with oxalate secretion, acid secretion, abscisic acid anabolism, ROS metabolic process, double fertilization, syngamy, lipolysis, proteasome degradation, and the ascorbate-glutathione cycle.
