BTR1 — Triticum turgidum subsp. durum

Summary

TRITD6AV1G222190, designated BTR1 on durum wheat chromosome 6A, encodes a K Homology domain-containing protein with calcium-dependent protein serine/threonine kinase activity, ssRNA binding, and protein kinase activity. The gene is associated with regulation of stomatal opening and closure, abscisic acid-mediated signaling, reactive oxygen species metabolism, and responses to salinity, osmotic stress, and bacterial defence. It has been linked to leaf elongation rate, biomass yield, seed yield, water use efficiency, transpiration rate, root thickness, flowering time, and seed dormancy. The encoded protein localises to the cytosol, plasma membrane, cytoplasm, and nucleus. Related genes in other species are linked to stomatal regulation, drought tolerance, freezing tolerance, abscisic acid signaling, and viral coat protein accumulation.
