Transient Gene Expression for the Characteristic Signal Sequences and the Estimation of the Localization of Target Protein in Plant Cell

[Abstract]  We have proposed and tested a method for characterization of the signal sequences and determinations of target protein localization in a plant cell. This method, called the AgI-PrI, implies extraction of protoplasts from plant tissues after agroinfiltration. The suggested approach combines the advantages of two widely used methods for transient gene expression in plants–agroinfiltration and transfection of isolated protoplasts. The AgI-PrI technic can be applied to other plant species. [摘要]  我们已经提出并测试了用于表征信号序列和确定植物细胞中目标蛋白质定位的方法。 这种称为AgI-PrI的方法意味着在农杆菌浸润后从植物组织中提取原生质体。 所提出的方法结合了两种广泛使用的用于植物中瞬时基因表达的方法的优点 - 农杆菌浸润和转分离的原生质体。 AgI-PrI技术可应用于其他植物物种。

【背景】迄今为止,已经开发并广泛使用以下用于植物中基因瞬时表达的技术:农杆菌渗入,植物外植体的生物射弹和使用聚乙二醇或电穿孔转染原生质体。这些方法的有效性已被清楚地证明。植物中瞬时表达基因的每种策略以及其益处具有其局限性和缺点,例如由于植物表皮细胞的复杂形状(农杆菌浸润)导致的重组报道蛋白在植物细胞区室中的良好成像困难,低转化效率以及专用设备和辅助材料(用于生物弹)的必要性,以及高活性原生质体产量和有效转染所需的复杂准备程序。这是开发和测试用于在植物细胞中瞬时表达基因的新方法的原因,优选通过改进实验方案并保留研究结果的生理意义。由于蛋白质在包括植物在内的活生物体中的细胞定位与它们的功能密切相关,活细胞中蛋白质的良好可视化成为评估蛋白质功能的重要工具。

[Abstract]  Plant parasitic nematodes are devastating pests on many crops. Juveniles (J2) of cyst nematodes invade the roots to induce a syncytium. This feeding site is their only source of nutrients. Male nematodes leave the roots after the fourth molt to mate with females. The females stay attached to their syncytia throughout their life and produce hundreds of eggs, which are contained in their bodies. When the females die their bodies form the cysts, which protect the eggs. Cysts can survive for many years in the soil until favorable conditions induce hatching of the juveniles.

[摘要]  植物寄生线虫是许多作物上的毁灭性害虫。 孢囊线虫的幼虫(J2)侵入根以诱导合胞体。 这个饲养场是他们唯一的营养来源。 雄性线虫在第四蜕皮后离开根以与雌性交配。 雌性在其整个生命期间保持附着于其合胞体,并产生数百个鸡蛋,其包含在它们的身体中。 当女性死于他们的身体形成囊肿,保护卵。 囊肿可以在土壤中存活多年,直到有利条件诱导幼鱼孵化。
