Screening Carica papaya native promoters driving stilbene synthase expression in Arabidopsis thaliana for resveratrol glucoside (piceid) synthesis

The use of promoters for downstream metabolic engineering in plants requires efficiently screening their transcriptional strength and the resulting levels of the desired metabolite. Carica papaya is a complex slow-growing tropical tree, which is difficult to rapidly screen for promoter activity. Therefore, we used the simple model system, Arabidopsis thaliana (Columbia), to compare the effectiveness of two native papaya promoters (Cp9 and Cp29)...
