Abstract:
The DNA fragment was cloned from the cDNA that was synthesized using the RNA from Chinese white poplar and verified by sequencing This cDNA clone ,designated PtoCesA1, was 3215 bp long with an opening reading frame of 2934bp extending from nucleotides 52~2985.Comprision of the nucleotide sequence of PtoCesA1 with PtrCesA1 showed 97% identity.For construction of the PtoCesA1 binary expression vector, the BamHI site was made by synonymy mutation, the full length PtoCesA1 cDNA was subcloned into pBI121 between the BamHI site and XbaI site. The PtoCesA1 binary vector,containing PtoCesA1,was verified by digestion and PCR.
