HOG1 — Brachypodium distachyon

Summary

Brachypodium distachyon gene HOG1 (BRADI_4G19457V3) encodes an adenosylhomocysteinase (EC 3.13.2.1) and is also annotated with adenosine kinase, mRNA 5'-cap guanine-N7-methyltransferase, red/far-red light photoreceptor, phosphorelay sensor kinase, histidine kinase, sequence-specific DNA binding, copper binding, and protein homodimerization activities. HOG1 is associated with the S-adenosyl-L-methionine cycle, one-carbon metabolism, mRNA capping, adenosine salvage, abscisic acid metabolism, hydrogen peroxide-mediated signaling, circadian regulation, stomatal complex development, and regeneration. The gene is linked to numerous agronomic traits including biomass yield, yield, seed yield, photosynthetic ability, phosphorus uptake, photoperiod-sensitive flowering time, leaf angle, leaf curling, root phototropism, lateral root length, stamen length, shoot axis branching, and sensitivities to glyphosate, gibberellic acid, jasmonic acid, ethylene, brassinosteroids, red light, and UV-B light. HOG1 is also associated with DNA methylation, cytosine methylation, gene silencing, pectin methylation, transmethylation, seed germination under abiotic stress, and circadian rhythm. The protein localizes to the cytosol, cytoplasm, plasmalemma, vacuole, apoplast, plasmodesma, and nuclear body.
