Rosa chinensis RcPP2C24 gene and application thereof in regulation and control of plant drought tolerance

The invention discloses a rosa chinensis RcPP2C24 gene and an application thereof in regulation and control of plant drought tolerance. The nucleotide sequence of the Chinese rose RcPP2C24 gene is as shown in SEQ ID No. 1, and the RcPP2C24 gene is as shown in SEQ ID No. 2. The sequence of the corresponding protein is as shown in SEQ ID NO: 2. The RcPP2C24 gene is subjected to water loss stress induced expression, and the drought tolerance of the tobacco can be reduced by over-expression of the gene in the tobacco; the dehydration stress tolerance of the Chinese rose petals can be improved by knocking out the gene in the Chinese rose. The invention lays a foundation for the research on the drought-enduring molecular mechanism of the Chinese rose, provides excellent genes for cultivating drought-enduring water-saving excellent Chinese rose varieties through a gene editing technology in the future, and has practical significance for the improvement of the Chinese rose varieties. 本发明公开一种月季RcPP2C24基因及其在调控植物耐旱性中的应用
