A 966-bp fragment of phloem protein 2 (PP2) gene in the promoter region of Cucurbita maxima was amplified by PCR. The fragment was cloned into pUCm-T vector, and a new recombined vector named pUCm-PSP was obtained. A new plant expression vector named pHZ03, in which the green fluorescent protein reporter gene is droved by PSP, was constructed after cutting vectors pUCm-PSP and pCAMBIA1302 with restriction enzymes, subsequent recovering, ligation, transformation and identification.
