| 摘要 |
The present invention relates to rice-specific microRNA, miR820, gene effective to control tillering and floral development through gene isolation, cloning and functional verification from the Indian Oryza species. This invention relates to nucleotide sequence (containing the nucleotide fragment of miR820) is linked to an exogenous promoter, and wherein the promoter is optionally a constitutive or inducible promoter, and introduced into Indica rice cultivar. The transgenic rice plants have improved agronomic characteristics, including greater tillering, abundant panicles and more flowers, as compared to the wild type plants cultivated in the same conditions. |
