Gene Details:

• MSU gene ID: LOC_Os10g35550
• RAPdb gene ID: Os10g0498600
• Gene Symbol: Du1
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• To understand the molecular mechanism that regulates the starch biosynthesis in rice grains, we characterized a classic rice mutant dull endosperm1 (Du1) and isolated Du1 through a map-based cloning approach.
• Du1, encoding a member of pre-mRNA processing (Prp1) family, is expressed mainly in panicles.
• Du1 specifically affects the splicing efficiency of Wx(b) and regulates starch biosynthesis by mediating the expression of starch biosynthesis genes.
• These results strongly suggest that Du1 may function as a regulator of the starch biosynthesis by affecting the splicing of Wx(b) and the expression of other genes involved in the rice starch biosynthetic pathways.
• Du1, encoding a novel Prp1 protein, regulates starch biosynthesis through affecting the splicing of Wxb pre-mRNAs in rice (Oryza sativa L.).
