The bioinformatic analysis of PG promoter sequences was conducted. PG promoter elements were predicted and analyzed by PLANTCARE and PLACE. The results showed that tomato PG promoter contained multiple c/s-acting regulatory elements such as typical basic elements TATA-Box and CAAT-Box, light responsive elements 3-AF1 binding site, ATl-motif, ATCT- motif, Box 4, Box I, GA-motif, GTl-motif, Spl and MRE, heat stress-responsive element HSE, ethylene-responsive element ERE, meristem-specifie regulatory element CCGTCC-box, endosperm expression-related regulatory elements GCN4_motif and Skn-l_motif, defense and stress responsiveness element TC-rich repeats, and circadian control-related element circadian, indicating that the expression of tomato PG gene is related to light, temperature, hormone, stress and other factors. This study laid the foundation for subsequent research about regulation of PG gene expression in plants.展开更多
