摘要：[Objective]The aim was to explore the function of wrky transcription factor in tomato.[Method]The primers were designed in this study according to the obtained wrky fragments,and the total RNA from tomato treated with 100 μmol/L of JA for 6 h was used as the template for RT-PCR.[Result]The 608 bp fragment was obtained from tomato with RT-PCR *** analysis indicated that this sequence contained wrkyGQK conservative domain and the similarity with Capsicum annuum wrky-c and Nicotiana tabacum Ntwrky-7 were 79% and 74%,respectively.[Conclusion]wrky gene sequence in tomato was cloned successfully.
