D14 — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.7HG0663620 (HvD14) on barley chromosome 7H encodes a protein with an alpha/beta hydrolase fold and esterase activity. It is associated with strigolactone and karrikin responses, shoot morphogenesis, secondary shoot formation, cuticle development, de-etiolation, leaf senescence, auxin polar transport, meristem organisation, seed germination, arbuscular mycorrhizae formation, ABA signaling, and ubiquitin-dependent proteolysis. The protein localises to the cytosol, nucleus, and SCF ubiquitin ligase complex. HvD14 has been connected to traits including abscisic acid, cytokinin, and jasmonic acid content, leaf relative water content, axillary bud morphology, root branching, bacterial blight resistance, drought sensitivity, stomatal closure, anthocyanin content, flowering time, seed yield, and responses to low temperature and oxidative stress. Studies of related genes in other species link the family to strigolactone perception, plant branching, flowering time, and drought resistance.
