摘  要:
将禽流感病毒M2e与鸡IgG Fc的融合基因转入烟草植株,利用烟草生产禽流感抗原蛋白,探索利用植物作为生物反应器生产禽流感疫苗的可行性。将M2e-Fc融合基因克隆到植物表达载体pBI121中,与CaMV35s启动子相连,以烟草子叶作为外植体,利用农杆菌介导法将外源基因转入烟草中。对抗性植株进行了PCR、RT-PCR分析。结果表明,M2e基因已经导入到烟草中,在转录水平得到了表达。为进一步利用转基因植物生产禽流感疫苗进行了前期的探索工作。

摘  要:
Fusion protein of avian influenza virus matrix 2 protein ectodomain segments(M2e) and avain IgG Fc was transformed into tobacco.To investigate the feasibility of developing transgenic plant vaccine of AIV,tobacco was used to produce antigen protein.M2e-Fc fusion was introduced into the corresponding cloning sites of binary vector pBI121,under the drive of CaMV35s promoter.Taking the leaf explants as the transformation receptors,M2e-Fc was transformed into tobacco by agrobacterium mediated transformation.Resistant plants were detected by PCR and RT-PCR.The results proved that M2e-Fc had been integrated into the genome of tobacco and expressed.It is applicable to use plant bioreactor to produce AIV H5N1 antigen protein in plant.
