D14 — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.4HG0368950 (HvD14) on barley chromosome 4H 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 linked to traits including shoot branching, root development, plant height, grain yield, seed-setting rate, drought sensitivity, heat tolerance, bacterial blight resistance, flowering time, and responses to nitrogen deficiency, oxidative stress, and low temperature. Studies of related genes in other species connect the family to strigolactone perception, lateral shoot formation, flowering time, and root architecture.
