Gene Details:

• MSU gene ID: LOC_Os02g34850
• RAPdb gene ID: Os02g0554000
• Gene Symbol: SDG725
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• Here, we report that rice SDG725 encodes a H3K36 methyltransferase, and its down-regulation causes wide-ranging defects, including dwarfism, shortened internodes, erect leaves and small seeds.
• Taken together, our data indicate that SDG725-mediated H3K36 methylation modulates brassinosteroid-related gene expression, playing an important role in rice plant growth and development.
• Consistently, transcriptome analyses revealed that SDG725 depletion results in down-regulation by more than two-fold of over 1000 genes, including D11, BRI1 and BU1, which are known to be involved in brassinosteroid biosynthesis or signaling pathways.
• Chromatin immunoprecipitation analyses showed that levels of H3K36me2/3 are reduced in chromatin at some regions of these brassinosteroid-related genes in SDG725 knockdown plants, and that SDG725 protein is able to directly bind to these target genes.
