Gene Details:

• MSU gene ID: LOC_Os02g52550
• RAPdb gene ID: Os02g0763000
• Gene Symbol: TGW2
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• Natural variation in the promoter of TGW2 determines grain width and weight in rice.
• <U+2022> A single nucleotide polymorphism (SNP) variation at 1818<U+00A0>bp upstream of TGW2 is responsible for its different expression, leading to alteration in grain width and weight by influencing cell proliferation and expansion in glumes.
• TGW2 interacts with KRP1, a regulator of cell cycle in plant, to negatively regulate grain width and weight.
• Genetic diversity analysis of TGW2 in 141 rice accessions revealed it as a breeding target in a selective sweep region.
• The sequence variation and candidate grain shape-related gene TGW2 were identified through Fst and sweep selective analysis.
