NJAU 4742（Tgui）可作为一种有前途的菌株用于开发新型生物肥料和生物杀菌剂。研究了通过接种用Tgui引发的植物，以阐明促进根生长和发育以及激活植物先天免疫应答的潜在机制。对玉米和拟南芥中防御相关基因和参与生长素信号传导途径的基因的相对表达进行了定量。扫描电子显微镜（SEM）进行可视化Tgui在玉米根中的定殖，并使用蛋白质组学方法来识别Tgui衍生的激发子。玉米根际Tgui的建立导致玉米中生长素合成途径的刺激，随后导致植物生长增加。Tgui胞外蛋白诱导了玉米对轮枝镰刀菌（Fusarium verticillioides，Fv）（肉座菌目，子囊菌门）的系统抗性（ISR），这种系统抗性可能与玉米组织中活性氧（ROS）的积累和胼胝质沉积增加有关。玉米免疫反应的激活是由Tgui分泌到根际的胞外蛋白混合物引发的。因此，我们的研究有助于更好地了解T。和植物根。
NJAU 4742 (Tgui) can serve as a promising strain for the development of novel biofertilizers and biofungicides. Plants primed with Tgui via inoculation were investigated to clarify the underlying mechanisms that promote root growth and development and activate the plant innate immune response. The relative expression of defence-related genes and of genes involved in the auxin signalling pathway in Zea mays and Arabidopsis thaliana was quantified. Scanning electron microscopy (SEM) was performed to visualize the colonization of Tgui in maize roots, and a proteomic approach was used to identify Tgui-derived elicitors. The establishment of Tgui in the rhizosphere of maize leads to the stimulation of the auxin synthesis pathway in maize and subsequently leads to increased plant growth. And the extracellular proteins of Tgui induced systemic resistance (ISR) of maize plants to Fusarium verticillioides (Fv) (Hypocreales, Ascomycota); the ISR of maize plants may be linked to the accumulation of reactive oxygen species (ROS) and increased deposition of callose in maize tissue. Activation of the maize immune response was triggered by the mixture of extracellular proteins secreted by Tgui into the rhizosphere. Our study thereby contributes to a better understanding of the interaction between T. guizhouense and plant roots.
