KC1 — Sorghum bicolor

Summary

SbKC1, a sorghum gene on chromosome 4, encodes a protein belonging to the KAT/AKT family, with outward rectifier potassium channel activity and ion transporter activity. This gene is associated with the regulation of membrane potential, upregulation of stomatal opening, and potassium ion homeostasis and transport. It has been linked to a wide range of agronomic traits, including yield, leaf necrosis tolerance, water stress response trait, transpiration rate, days to flowering trait, and responses to alkali soil sensitivity, magnesium sensitivity, nitrogen sensitivity, and cadmium concentration. Associations also extend to sucrose content, root mass density, and lateral root length. Related genes in other species connect the family to potassium translocation, drought and salt stress tolerance, and osmotic stress tolerance.
