Since the 1980s, numerous mutualistic Pseudomonas spp. strains have been used in studies on the biology of plant growth-promoting rhizobacteria (PGPR) and their interactions with host plants. In 1988, a strain from the Pseudomonas fluorescens group, WCS417, was isolated from lesions of wheat roots growing in a take-all disease-suppressive soil. In subsequent trials, WCS417 limited the build-up of take-all disease in field-grown wheat and significantly increased wheat yield. In 1991, WCS417 was featured in one of the first landmark studies on rhizobacteria-induced systemic resistance (ISR), in which it was shown to confer systemic immunity in carnation (Dianthus caryophyllus) against Fusarium wilt. The discovery that WCS417 conferred systemic immunity in the model plant species Arabidopsis thaliana in 1996 incited intensive research on the molecular mechanisms by which PGPR promote plant growth and induce broad-spectrum disease resistance in plants. Since then, the strain name appeared in over 750 studies on beneficial plant-microbe interactions. In this review, we will highlight key discoveries in plant-microbe interactions research that have emerged from over 30 years of research featuring WCS417 as a model rhizobacterial strain. WCS417 was instrumental in improving our understanding of the microbial determinants that are involved in root colonization and the establishment of mutually beneficial interactions with the host plant. The model strain also provided novel insight into the molecular mechanisms of plant growth promotion and the onset and expression of rhizobacteria-ISR. More recently, WCS417 has been featured in studies on host immune evasion during root colonization, and chemical communication in the rhizosphere during root microbiome assembly. Numerous studies on the modes of action of WCS417 have provided major conceptual advances in our understanding of how free-living mutualists colonize the rhizosphere, modulate plant immunity, and promote plant growth. The concepts may prove useful in our understanding of the molecular mechanisms involved in other binary plant-beneficial microbe interactions, and in more complex microbial community contexts, such as the root microbiome.

Pseudomonas simiae WCS417:模型有益根际细菌的星迹

自 1980 年代以来,许多共生假单胞菌属。菌株已用于研究植物生长促进根际细菌 (PGPR) 的生物学及其与宿主植物的相互作用。1988 年,荧光假单胞菌属的菌株 WCS417 从生长在抑制病害的土壤中的小麦根部病变中分离出来。在随后的试验中,WCS417 限制了田间小麦全病害的积累,并显着提高了小麦产量。1991 年,WCS417 出现在关于根际细菌诱导的系统抗性 (ISR) 的首批具有里程碑意义的研究之一中,其中显示它赋予康乃馨(石竹属)系统免疫对抗枯萎病。1996 年 WCS417 赋予模式植物拟南芥全身免疫的发现激发了对 PGPR 促进植物生长和诱导植物广谱抗病性的分子机制的深入研究。从那时起,该菌株名称出现在 750 多项关于有益植物-微生物相互作用的研究中。在这篇综述中,我们将重点介绍植物-微生物相互作用研究中的重要发现,这些发现是 30 多年来以 WCS417 作为模型根际细菌菌株的研究中出现的。WCS417 有助于提高我们对根系定植和与宿主植物建立互惠互利相关的微生物决定因素的理解。该模型菌株还为植物生长促进的分子机制和根际细菌-ISR 的发生和表达提供了新的见解。最近,WCS417 已在根定植期间宿主免疫逃避和根微生物组组装期间根际化学通讯的研究中发挥重要作用。对 WCS417 作用模式的大量研究为我们理解自由生活的共生者如何定殖根际、调节植物免疫和促进植物生长提供了重大的概念进步。这些概念可能有助于我们理解其他二元植物与有益微生物相互作用的分子机制,以及更复杂的微生物群落环境,例如根微生物组。WCS417 在根定植期间宿主免疫逃避和根微生物组组装期间根际化学通讯的研究中占有重要地位。对 WCS417 作用模式的大量研究为我们理解自由生活的共生者如何定殖根际、调节植物免疫和促进植物生长提供了重大的概念进步。这些概念可能有助于我们理解其他二元植物与有益微生物相互作用的分子机制,以及更复杂的微生物群落环境,例如根微生物组。WCS417 在根定植期间宿主免疫逃避和根微生物组组装期间根际化学通讯的研究中占有重要地位。对 WCS417 作用模式的大量研究为我们理解自由生活的共生者如何定殖根际、调节植物免疫和促进植物生长提供了重大的概念进步。这些概念可能有助于我们理解其他二元植物与有益微生物相互作用的分子机制,以及更复杂的微生物群落环境,例如根微生物组。对 WCS417 作用模式的大量研究为我们理解自由生活的共生者如何定殖根际、调节植物免疫和促进植物生长提供了重大的概念进步。这些概念可能有助于我们理解其他二元植物与有益微生物相互作用的分子机制,以及更复杂的微生物群落环境,例如根微生物组。对 WCS417 作用模式的大量研究为我们理解自由生活的共生者如何定殖根际、调节植物免疫和促进植物生长提供了重大的概念进步。这些概念可能有助于我们理解其他二元植物与有益微生物相互作用的分子机制,以及更复杂的微生物群落环境,例如根微生物组。
