H1 — Brachypodium distachyon

Summary

BdH1 (BRADI_5G19000V3) on chromosome 5 of Brachypodium distachyon encodes a histone H1/H5 family protein with structural constituent of chromatin activity, double-stranded telomeric DNA binding, DNA glycosylase activity, AP deoxyendoribonuclease activity, NAD ADP-ribosyltransferase activity, SUMO binding, and DNA demethylase activity. It is associated with nucleosome assembly, chromosome condensation, DNA ADP-ribosylation, base excision repair, non-homologous end joining, cell cycle G2/M phase transition, regulation of mitotic entry, epigenetic programming in the endosperm, guard mother cell differentiation, lateral root formation, embryo development ending in seed dormancy, and response to thirst. The gene is linked to traits including flowering time, seed development, root hair length, root thickness, disease tolerance, abiotic stress response, pollen fertility restoration, and cell cycle traits. Related genes in other species are linked to DNA damage tolerance, pathogen defense, and drought response.
