摘要
Abstract Leaves of melon were collected and extracted by the CTAB method for total DNA which was used for PCR amplification, obtaining the gene sequence of cucumisin promoter. The sequence results were processed and analyzed with DNAman, DNAstar and other softwares, and bioinformatic element analysis was performed with PlantCARE and PLACE. The analysis results showed that the cucumisin promoter shared 100%, 99% and 99% homology with AY055805, LN713264 and LN681897, respectively. The promoter sequence contains a variety of c/s-acting elements common in fruit promoters of higher plants such as TATA-Box and CAAT-Box, and light-responsive elements, some of which involved in ABA and VP1 responsiveness and salicylic acid responsiveness. This study provides a scien- tific basis for further research on genetic engineering of fruits.
