Green fluorescent protein(GFP)gene and neomycin phosphoric acid transferase(NPTⅡ)gene have been widely used in plant genetic transformation.In order to investigate the genetic transformation efficiency of nptⅡ::gfpfusion gene in citrus,Agrobactirum-mediated genetic transformation of Jincheng orange(Citrus sinensis)with the pNGM vector containing the nptⅡ::gfpfusion gene under the control of CaMV35 spromoter,using the pNPTⅡ-GF vector containing both nptⅡ gene and gfpgene as a control was established.Results ...
