HAP4 — Oryza sativa Indica Group

Summary

BGIOSGA011163 (HAP4, also known as UBQ13, ERD16, and RPL40A) on chromosome 3 of indica rice encodes a protein with ubiquitin and ribosomal eL40 domains, annotated with histone methylase activity, core promoter sequence-specific DNA binding, thiol-dependent deubiquitinase activity, and structural constituent of the ribosome. The gene is associated with regulation of abscisic acid anabolism, salinity response, seed dormancy, stomatal lineage progression, trichome branching, and response to freezing and thermal stimulus. It is linked to grain weight, grain yield, grain shape, seed size, seed growth and development, leaf length, leaf senescence, root mass density, root morphology, shoot axis branching, flowering time, pollen fertility, chloroplast development, metabolite content, and disease tolerance. Localisation evidence connects it to the ribosome, cytosolic large ribosomal subunit, endosomes, and the ESCRT I complex.
