High thousand seed weight gene of common wheat as well as construction method and application of high thousand seed weight gene

The invention relates to the technical field of gene synthesis and application, in particular to a common wheat high thousand seed weight gene as well as a construction method and application of the gene. The open reading frame sequence of the gene is as shown in SEQ ID NO.1, the genome sequence of the gene is as shown in SEQ ID NO.2, and the gene is named as TaCHLI-7A. The TaCHLI-7A is used for supplementing the wheat variety stone 4185, so that the leaf width and the chlorophyll content can be obviously increased; the TaCHLI-7A is used for supplementing the wheat variety stone 4185, so that the size and thousand seed weight of grains can be obviously increased; the TaCHLI-7A is used for supplementing the wheat variety stone 4185, so that the single-plant yield of wheat can be obviously improved. 本发明涉及基因合成和应用技术领域，具体的为一种普通小麦高千粒重基因以及该基因的构建方法和应用。该基因的开放阅读框序列如SEQ ID NO.1所示、基因组序列如SEQ ID NO.2所示，该基因命名为TaCHLI-7A。用TaCHLI-7A回补小麦品种石4185能够显著增加叶片宽度和提高叶绿素含量；用TaCHLI-7A回补小麦品种石4185能够显著增加籽粒的大小和千粒重；用TaCHLI-7A回补小麦品种石4185能够显著提高小麦
