Rice CHD3/Mi-2 chromatin remodeling factor RFS regulates vascular development and root formation by modulating the transcription of auxin-related genes NAL1 and OsPIN1.

ABSTRACT: The vascular system in plants facilitates long-distance transportation of water and nutrients through the xylem and phloem, while also providing mechanical support for vertical growth. Although many genes that regulate vascular development in rice have been identified, the mechanism by which epigenetic regulators control vascular development remains unclear. This study found that Rolled Fine Striped (RFS), a Chromodomain Helicase DNA-binding 3 (CHD3)/Mi-2 subfamily protein, regulates vascular development in rice by affecting the initiation and development of primordia. The rfs mutant was found to affect auxin-related genes, as revealed by RNA sequencing and reverse transcription-quantitative PCR analysis. The transcript levels of OsPIN1 and NAL1 genes were downregulated in rfs mutant, comp
