With the rapid development of molecular biology, especially bioinformatics and genomics,gene cloning related to grain weight in common wheat has also been further studied. This paper mainly introduces the progress of genetic and functional researches on grain weight related genes in wheat, including TaGS5, TaGASR7, TaSus, TaWSC, Ta-6-SFT, TaGW2, TaCKX, TaTGW6, TaCWI, and TaGS1 and gene family of TaTEF, TaSAP, and TaSnRK2s, which provides the corresponding theory and technology support in molecular breeding of wheat. |
