CKX1 — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.7HG0716480, designated HvCKX1 on chromosome 7H of domesticated barley, encodes a cytokinin dehydrogenase with FAD-binding and redox activity. This gene is associated with cytokinin metabolism and signaling, inflorescence and seed development, tRNA processing, immune and defense responses, and amino acid anabolism. It has been linked to grain yield, plant height, tiller number, root morphology and length, cytokinin content and sensitivity, and disease tolerance. The encoded protein localises to the endoplasmic reticulum, cytosol, nucleus and extracellular space. Related genes in other species are linked to cytokinin deficiency.
