Chinese cymbidium organ development regulatory gene as well as coding protein and application thereof

The invention discloses a cymbidium organ development regulatory gene as well as a coding protein and application thereof. The cymbidium organ development regulatory gene is isolated from flower organcDNA of Chinese cymbidium sinense, and a nucleotide sequence is as shown by SEQ ID NO. 1; and an amino acid sequence of the cymbidium organ development regulatory protein is as shown by SEQ ID NO. 2.By virtue of the gene engineering technology, the cymbidium organ development regulatory gene is excessively expressed in Arabidopsis and cymbidium, the plant flower type can be changed, flower petals are curved, the cymbidium flower petals are converted to lips, and the lip traits are improved; and therefore, the gene and the protein coded by the gene are applied to the research of orchidaceae flower organ development regulation way as well as the improvement of plant blossoming trait petal shape. 本发明公开了种国兰花器官发育调控基因及其编码蛋白与应用。所述的国兰花器官发育调控基因是从中国兰花的墨兰品种"达摩"(Cymbidium sinense)的花器官cDNA中分离得到，其核苷酸序列如SEQ ID NO:1所示；所述的国兰花器官发育
