In order to explore the effects of rose TCP9 gene on development regulation of floral organ, binary expression vector was built in the plant by the application of CRISPR/Cas9 technology. Test results showed that plants containing TCP9 gene expression vector was constructed successfully. Arabidopsis thaliana, as receptor, was transformed by using inflorescence infection method with Agrobacterium so as to obtain transformed plants. Phenotypic variation of transformed plants was significantly. The number of petals and stamens increased and reduced, respectively, and pistil stigma bent. Results in...
