ENP — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.5HG0451550 (HvENP) on barley chromosome 5H encodes an NPH3/RPT2-like domain protein with blue light photoreceptor activity, FMN binding, and multiple kinase activities. The gene is associated with apical protein localization, auxin polar transport, chloroplast accumulation movement, basipetal auxin transport, and plant organ morphogenesis. It has been linked to phototropism responses, root and leaf development traits, seed yield, biomass yield, and sensitivity to multiple hormones including gibberellic acid, cytokinin, ethylene, and brassinosteroids. Associations also include viral disease response, biotic stress tolerance, and vegetative to reproductive phase transition. The gene product localizes to the plasma membrane, CRL complex, vesicles, and ubiquitin ligase complex. Studies of related genes in other species connect the family to phototropism, chloroplast migration, and root growth regulation.
