HISTONE MONOUBIQUITINATION1 (HUB1) and its paralog HUB2 act in a conserved heterotetrameric complex the chromatin-mediated transcriptional modulation of developmental programs, such as flowering time, dormancy, circadian clock. The KHD1 SPEN3 proteins were identified interactors HUB1 with vitro RNA-binding activity. Mutants had reduced rosette leaf areas. Strikingly, spen3 mutants, time was slightly, but significantly, delayed, opposed to early hub1-4 mutant. mutant phenotypes biomass...
ABSTRACT The Elongator complex (hereafter Elongator) promotes RNA polymerase II-mediated transcript elongation through epigenetic activities such as histone acetylation. regulates growth, development, immune response and sensitivity to drought abscisic acid. We demonstrate that elo mutants exhibit defective hypocotyl but have a normal apical hook in darkness are hyposensitive light during photomorphogenesis. These phenotypes supported by transcriptome changes, including downregulation of...
SUMMARY Rhythmic oscillation of biological processes helps organisms adapt their physiological responses to the most appropriate time day. Chromatin remodeling has been described as one molecular mechanisms controlling these oscillations. The importance changes in transcriptional activation well maintenance heterochromatic regions widely demonstrated. However, little is still known on how diurnal can impact global status chromatin modifications and, hence, control gene expression. In plants,...
