Chromatin Remodeling Complex SWR1 Regulates Root Development by Affecting the Accumulation of Reactive Oxygen Species (ROS).

ABSTRACT: Reactive oxygen species (ROS), a type of oxygen monoelectronic reduction product, play integral roles in root growth and development. 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 Arabidopsis. Our transcriptome results and gene ontology (GO) enrichment analysis showed that the oxidoreductase activity-related genes significantly changed in mutants for the Arabidopsis SWR1 complex components, such as arp6 and pie1, and histone variant H2A.Z triple mutant hta8 hta9 hta11. The three encoding genes in Arabidopsis are the three H2A.Z v
