GI — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.3HG0294970 (HvGI) on barley chromosome 3H encodes a DNA-3-methyladenine glycosylase, a DNA repair enzyme with metal-binding activity that initiates base excision repair (BER). The gene is also associated with photoperiodism and localised to the nucleus. HvGI has been linked to anthesis time. Studies of related genes in other species connect the family to seed germination, seed dormancy, seed maturation, node number, drought tolerance, and photochemical quenching, as well as climatic adaptation traits such as temperature minima and maxima.
