is a plant growth-promoting rhizobacteria (PGPR) that has significant biocontrol properties. Wheat sheath blight caused by is a significant soil-borne disease of wheat that causes significant losses in wheat production, and the biological control against the disease has received extensive attention. ZYPP18 was identified using morphological and molecular characterization. An antagonistic activity experiment verified that ZYPP18 inhibits the growth of on artificial growth media. A detached leaf assay verified that ZYPP18 inhibits the expansion of wheat sheath blight on the detached leaf. ZYPP18 has been found to possess plant growth-promoting properties, as well as the ability to solubilize phosphate and generate indole-3-acetic acid. Results from hydroponic experiments showed that wheat seedlings treated with ZYPP18 grew faster. Additionally, pot experiments and field experiments demonstrated that ZYPP18 effectively controls the occurrence of wheat sheath blight. ZYPP18 reduced the incidence of wheat sheath blight in wheat seedlings by 37.37% and 37.90%, respectively. The control effect of ZYPP18 on wheat sheath blight was 56.30% and 65.57%, respectively. These findings provide evidence that ZYPP18 is an effective biological factor that can control disease and promote plant growth.
是一种具有显著生物防治特性的植物促生根际细菌（PGPR）。由[未提及的病原菌]引起的小麦纹枯病是小麦一种重要的土传病害，会导致小麦产量大幅损失，针对该病害的生物防治受到了广泛关注。ZYPP18通过形态学和分子特征鉴定得到。拮抗活性实验证实ZYPP18在人工生长培养基上抑制[未提及的病原菌]的生长。离体叶片试验证实ZYPP18抑制离体叶片上小麦纹枯病的扩展。已发现ZYPP18具有促进植物生长特性，以及溶解磷酸盐和产生吲哚 - 3 - 乙酸的能力。水培实验结果表明，用ZYPP18处理的小麦幼苗生长更快。此外，盆栽实验和田间实验表明ZYPP18能有效控制小麦纹枯病的发生。ZYPP18使小麦幼苗中小麦纹枯病的发病率分别降低了37.37%和37.90%。ZYPP18对小麦纹枯病的防治效果分别为56.30%和65.57%。这些发现证明ZYPP18是一种能控制病害并促进植物生长的有效生物因子。
