is a Gram-negative bacterium, which dissolves minerals, produces growth hormones, promotes root growth, and protects plants from different soil-borne pathogens. In the present study, roots, stalks, and fresh weight of maize ( L.) were significantly increased after soaking in compared with the control. Subsequently, transcriptome sequencing results of the whole maize plant soaked in showed that multiple growth and development-related genes were up-regulated more than 100-fold compared to the control. Furthermore, the abundance of plant growth promoting bacteria, such as Subgroup_6 and KD4-96, were increased significantly. On the contrary, the abundance of multiple pathogens, such as , and were significantly decreased. Moreover, inoculation with could inhibit the infection of the pathogen in maize. These results suggest that soaking seeds in may affect the expression of maize growth and development-related genes as the bacteria changes the soil microorganism community structure. These findings may help to expand the application of in crop production and provide new opportunities for food security.
是一种革兰氏阴性菌，它能溶解矿物质、产生生长激素、促进根系生长，并保护植物免受不同土壤传播病原体的侵害。在本研究中，与对照相比，玉米（ ）浸泡在 后，其根、茎和鲜重显著增加。随后，浸泡在 中的整株玉米的转录组测序结果表明，与对照相比，多个与生长发育相关的基因上调了100倍以上。此外，植物促生细菌如Subgroup_6和KD4-96的丰度显著增加。相反，多种病原体如 、 和 的丰度显著降低。此外，接种 可抑制玉米中病原体 的感染。这些结果表明，浸泡在 中的种子可能会影响玉米生长发育相关基因的表达，因为这种细菌改变了土壤微生物群落结构。这些发现可能有助于扩大 在作物生产中的应用，并为粮食安全提供新的机会。
