Gene Details:

• MSU gene ID: LOC_Os01g08420
• RAPdb gene ID: Os01g0179400
• Gene Symbol: SSG4
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• In this study, we report a novel rice (Oryza sativa) mutant called substandard starch grain4 (SSG4) that develops enlarged SGs in the endosperm.
• Enlargement of SGs in SSG4 was also observed in other starch-accumulating tissues such as pollen grains, root caps, and young pericarps.
• SSG4 will be a useful molecular tool for future starch breeding and biotechnology.
• The results of this study suggest that SSG4 influences the regulation of starch and lipid metabolism as well as amyloplast development, a finding that is useful for potential genetic improvement of rice grain quality in future starch and lipid breeding and biotechnology.
