In order to investigate the biological function of theChimonanthus praecox SAMTgene, here we reported thatthe plant binary expression vector pBI121-CpSAMTwas constructed and then theCpSAMTgene was introduced into pe-tunia throughAgrobacterium tumefaciensmediated transformation. PCR and RT-PCR was used to test the transgenicplants, and HS-SPME-GC-MS was employed to analyze the components of flower flavor. Results showed that nine inde-pendent transgenic lines obtained were positive. Further analysis showed t...
