The epigenetic mechanism plays a critical role in gene transcription and expression; however, its regulation of ROS metabolism in root development is still limited. We found that the chromatin remodeling complex SWR1 regulates root length and lateral root formation in <i>Arabidopsis</i>. Our transcriptome results and gene ontology (GO) enrichment analysis showed that the oxidoreductase activity-related genes significantly changed in mutants for the <i>Arabidopsis</i> SWR1 complex components, such as <i>arp6</i> and <i>pie1</i>, and histone variant H2A.Z triple mutant <i>hta8 hta9 hta11.</i> The three encoding genes in <i>Arabidopsis</i> are the three H2A.Z vPlants (Basel, Switzerland)Chromatin Remodeling Complex SWR1 Regulates Root Development by Affecting the Accumulation of Reactive Oxygen Species (ROS).PMC99640592022J0601432170352, 31970333PT2021007, PT2021003xjq202108Gui Ke AA22068096Xi XChai MLiu YMa SLiu KHuang YWang FQin YZhu WSu HCai HfalseChromatin Remodeling Complex SWR1 Regulates Root Development by Affecting the Accumulation of Reactive Oxygen Species (ROS).Reactive oxygen species (ROS), a type of oxygen monoelectronic reduction product, play integral roles in root growth and development.
