Abstract: To make use of plant fruit specific express foreign proteins, 1.2 kb AGPL1 gene promoter was amplified in watermelon leaves using PCR, and bioinformatics analysis of AGPL1 promoter sequences was conducted. The results showed by PlantCARE database and PLACE database that AGPL1 gene promoter had number of typical core elements such as TATA-Box, CAAT-Box, high level transcription cis-acting element 5UTR Py-rich stretch, photoresponse elements including ACE, ATCC-motif, Box 4, I-Box, Sp1, TCCC-motif, GAG-motif, MNF1, two gibberellin response elements GARE-motif and P-box, cis-acting element related to protein metabolic regulation O2-site, cis-acting element related to salicylic acid reaction TCA-element, induced anaerocabically cis-acting element ARE, element involved in defense and stress responsiveness TC-rich repeats, circadian rhythm controlling element circadian and so on, all of which lays the groundwork for such research on regulation of PG genes in the future.
