Plant cell walls play an important role in shaping the defense strategies of plants. This research demonstrates the influence of two differentiators: the lifestyle and properties of the Trichoderma species on cell wall changes in common wheat seedlings. The methodologies used in this investigation include microscopy observations and immunodetection. In this study was shown that the plant cell wall was altered due to its interaction with Trichoderma. The accumulation of lignins and reorganization of pectin were observed. The immunocytochemistry indicated that low methyl-esterified pectins appeared in intercellular spaces. Moreover, it was found that the arabinogalactan protein epitope JIM14 can play a role in the interaction of wheat roots with both the tested Trichoderma strains. Nevertheless, we postulate that modifications, such as the appearance of lignins, rearrangement of low methyl-esterified pectins, and arabinogalactan proteins due to the interaction with Trichoderma show that tested strains can be potentially used in wheat seedlings protection to pathogens.

普通小麦根与木霉菌有益菌相互作用后植物细胞壁的变化

植物细胞壁在塑造植物防御策略中起着重要作用。这项研究证明了两个差异因素的影响：木霉菌的生活方式和特性对普通小麦幼苗的细胞壁变化的影响。本研究中使用的方法包括显微镜观察和免疫检测。这项研究表明，植物细胞壁由于与木霉的相互作用而发生了改变。观察到木质素的积累和果胶的重组。免疫细胞化学表明低甲基酯化果胶出现在细胞间隙。此外，已发现阿拉伯半乳聚糖蛋白表位JIM14可以在小麦根与被测木霉菌的相互作用中发挥作用株。然而，我们推测由于与木霉菌的相互作用而产生的修饰，例如木质素的外观，低甲基酯化果胶的重新排列以及阿拉伯半乳聚糖蛋白，表明被测菌株可以潜在地用于小麦幼苗对病原体的保护。
