or MF3 taken alone at a concentration twice exceeding the content of each protein in the tested mixture. These findings open the prospects of a combined use of both elicitors. However, preparation of such mixture requires production of both proteins via their heterologous expression in two different E. coli clones transformed with the corresponding encoding genes. Moreover, the corresponding procedures of isolation and purification would be required for each protein. In this work, the MF2/MF3 chimeric protein was first obtained and its protective activity in the tobacco plant ( Nicotiana tabacum L.)  tobacco mosaic virus (TMV, family Virgaviridae , genus To-bamovirus , species Tobacco mosaic virus) pathosystem was demonstrated. It was also established for the first time that the protective activity of MF2/MF3 is not inferior to the activity of a mixture of individual proteins taken in equivalent concentrations. The purpose of our study was obtaining of a chimeric MF2/MF3 protein via heterologous expression in Escherichia coli and a comparison of its protective activity with that of individual MF2 or MF3 and their mixture. The chimeric MF2/MF3 protein is a structure composed of two domains, in which MF2 protein was linked to the N-term i nal region of MF3 via the polyalanine linker (AAALIAA). The MF2/MF3 protein encoding sequences were constructed by the use of classic and overlap PCR. Recombinant MF2/MF3 protein was expressed by transformed E. coli Rosetta cells in the form of a 25-kDa water-soluble protein and purified to the homogeneity by immobilized metal affinity chromatography (IMAC). To evaluate the antiviral activity of the MF2/MF3 hybrid and to compare its protective effect with that of individual proteins and their mixtures, a biotest with pre-inoculation treatments of detached tobacco leaves of the necrosis-forming variety Xanthi NN, which were then infected with TMV, was used. Plants were grown in a climate
或单独使用 MF3 的浓度是试验混合物中每种蛋白质含量的两倍。这些发现为联合使用这两种诱导剂开辟了前景。然而,制备这种混合物需要在两个不同的大肠杆菌克隆中用相应的编码基因进行异源表达来生产这两种蛋白。此外,每种蛋白质还需要相应的分离和纯化程序。在这项工作中,首次获得了 MF2/MF3 嵌合蛋白,并证明了它在烟草植物(Nicotiana tabacum L.) 烟草花叶病毒(TMV,病毒科,To-bamovirus 属,烟草花叶病毒种)病理系统中的保护活性。研究还首次证实,MF2/MF3 的保护活性并不亚于同等浓度的单个蛋白质混合物的活性。我们研究的目的是在大肠杆菌中通过异源表达获得嵌合 MF2/MF3 蛋白,并将其保护活性与单个 MF2 或 MF3 蛋白及其混合物的保护活性进行比较。嵌合 MF2/MF3 蛋白由两个结构域组成,其中 MF2 蛋白通过聚丙氨酸连接体(AAALIAA)与 MF3 的 N 端末端区域相连。通过经典和重叠 PCR 方法构建了 MF2/MF3 蛋白编码序列。重组 MF2/MF3 蛋白通过转化大肠杆菌 Rosetta 细胞以 25 kDa 水溶性蛋白的形式表达,并通过固定金属亲和层析(IMAC)纯化至均一。为了评估 MF2/MF3 混合物的抗病毒活性,并比较其与单个蛋白及其混合物的保护效果,使用了一种生物试验方法,即对坏死形成品种 Xanthi NN 的分离烟草叶片进行预接种处理,然后使其感染 TMV。植物生长在
