Beschreibung
Zusammenfassung:	The invention belongs to the field of plant genetic engineering, and discloses nucleotide sequences of an isolated and cloned gene GY6 and allelic genes thereof for controlling the rice grain yield. The sequences are shown as SEQ ID NO:1 (Zhenshan 97) and SEQ ID NO:4 (Miyang 46), and contain four exons; coding sequences thereof are shown as SEQ ID NO:2 and SEQ ID NO:5; and amino acid sequences are shown as SEQ ID NO:3 and SEQ ID NO:6. Both have 11 single nucleotide polymorphisms in a coding area so as to lead to 6 amino acid changes. A rice plant with trans-GY6 gene is obtained by utilizing atransgene technology, and the transgenic positive plants have the characteristics that the number of grains is increased, the thousand seed weight is improved, and the yield is increased.
