Related OfMYB1R70 gene for increasing synthesis of volatile organic substances in osmanthus fragrans as well as encoding protein and application of related OfMYB1R70 gene

The invention discloses a related OfMYB1R70 gene for increasing synthesis of volatile organic substances in osmanthus fragrans and an encoding protein and application thereof, and belongs to the field of plant molecular biology. The OfMYB1R70 gene is an MYB1R transcription factor gene, and the nucleotide sequence of the OfMYB1R70 gene is as shown in SEQ ID NO. 1. According to the invention, the full length of the gene sequence is obtained through cloning, an over-expression vector is constructed, and instantaneous transformation of the nicotiana benthamiana is carried out. The result shows that the substance content of the main volatile organic compound beta-ionone of the sweet osmanthus of the instantaneous transformation plant is obviously increased compared with that of a control group CK, and the content of other substances is obviously higher than that of the control group CK, so that the OfMYB1R70 plays an important role in increasing the volatile organic substances of the sweet osmanthus; the method ca
