D14 — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.4HG0398570, designated HvD14, encodes an alpha/beta hydrolase-fold protein with esterase activity and is annotated to protein binding. The gene is associated with strigolactone signaling, including cellular response to strigolactone, strigolactone anabolism, and the ubiquitination of D53 in response to strigolactone availability. HvD14 is linked to shoot morphogenesis, secondary shoot formation, and the regulation of meristem organisation, as well as auxin polar transport, cutin-based cuticle development, de-etiolation, and positive regulation of leaf senescence. Associations extend to abscisic acid and cytokinin content, drought sensitivity, bacterial blight disease resistance, seed yield, and responses to karrikin and low temperature stress. The protein localises to the cytosol, nucleus, and SCF ubiquitin ligase complex. Related genes in other species are linked to plant branching, flowering time, and drought resistance.
