Construction of bivalent plant expression vector with cold-induced gene of Chorispora bungeana in sugarcane
摘要
Abstract
[Objective]A new bivalent plant expression vector, named pCambial300-cbcorl5a-bar, was recombined by inserting two genes, I.e. Cbcor15a and eGFP, into the vector pCambial300-bar and replacing the promoter CaMV 35s with Ubi-1. [Method]Based on the multiple cloning sites of the expression vector pCambial300-bar, the primers were designed according to the nucleotide sequence of gene Cbcorl5a and eGFP and the promoter Ubi-1, and then the fragments of the genes and promoter were inserted into the vector pCambial300-bar. The plasmids of the vector pCambial300-cb-cor15a-bar were transduced into onion epidermal cells via particle bombardment. The results were observed through fluorescence microscopy and confocal laser scanning microscope, respectively. [Result]Compared to onion epidermal cell with pCambia 1300-bar, onion epidermal cell transduced with the recombinant vector plastnid had a very bright green florescence. [Conclusion]Downstream cold-induced gene Cbcorl5a and reporter gene eGFP regulaled by up-stream promoter Ubi-1 were expressed efficiently, which could ensure the construction of Cbcorl5a.关键词
