摘要:
研究我国野生葡萄燕山葡萄(Vitis yeshanesis ‘Yanshan’)VyUSP1基因在转基因烟草不同逆境下的表达情况,选择从供试材料中克隆所获得的VyUSP1基因,利用重组法构建其载体,并用农杆菌介质为导体转化转基因烟草植株,获得USP转基因烟草植株,然后对转基因烟草植株进行不同逆境处理,并对该基因进行初步的功能研究。结果表明,在不同的逆境条件下,USP转基因烟草均具有一定的抗干旱能力,但是不具备抗寒能力。较高浓度NaCl、甘露醇、PEG-6000以及低温处理会抑制转基因烟草种子的萌发。而在不同浓度NaCl、甘露醇处理下,转基因烟草植株幼苗均比野生型(WT)植株幼苗的表现要好;不同浓度PEG-6000处理对转基因烟草幼苗生长的影响并不明显;但在低温处理条件下,转基因烟草植株幼苗全部死亡。植物在受到外界胁迫时VyUSP1基因的表达会上调,蛋白活性被激活之后,有助于提高植物的抗逆性,增强其环境的适应性,因此USP对逆境胁迫存在一定的抗性。
