Gene OsEHD4 for controlling paddy rice heading stage and mutant and application thereof

The invention belongs to the technical field of gene engineering, and relates to a gene OsEHD4 for controlling a paddy rice heading stage and a mutant and an application thereof. The gene codes CCH zinc finger protein; a wild-type gene sequence is shown in SEQ ID NO. 1; and the gene promotes flowering under long or short sunshine conditions. The mutant gene has a DNA sequence as shown in SEQ ID NO. 3. Transgenosis experiments prove that the gene has the function of advancing the paddy rice heading stage.
