HAN — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.1HG0091840, also known as HAN, encodes a GATA-type zinc-finger protein with DNA-binding transcription activator activity, miRNA binding, and translation initiation factor activity. In barley, the gene is associated with bract suppression, and its product localises to the plastid and cytoplasm. The gene is linked to numerous developmental processes including specification of floral organ identity, carpel and stamen development, regulation of shoot apical meristem development, abaxial cell fate specification, and the transition from vegetative to reproductive phase. It is also associated with responses to salt, nitrogen compounds, gibberellin, absence of light, and antiviral defence. Associations with agronomic traits include drought tolerance, salt tolerance, disease tolerance, and reproductive period. Studies of related genes in other species link the family to bract and floral development, fruit valve formation, and Fusarium wilt resistance, as well as leaf, panicle, and flowering time traits.
