In order to investigate the stability of inheritance and expression of hepatitis A virus capsid protein fusion gene in transgenic Jincheng(Citrus sinensis(L.) Osbeck) lines and their vegetative propagation generations,two single-copy transgenic Jincheng lines were used as experiment materials and propagated vegetatively to produce 2 generations through grafting.PCR,Southern blotting and real-time PCR were performed.The results demonstrated that hepatitis A virus capsid protein fusion gene was stably inherit...
