Genbank accession number

• 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

• KRP1, TGW2, Natural variation in the promoter of TGW2 determines grain width and weight in rice., TGW2 interacts with KRP1, a regulator of cell cycle in plant, to negatively regulate grain width and weight
