概括

Fusarium avenaceum的攻击性因宿主作物而异. 豆衍生的Fusarium avenaceum分离物在豆,豆和小麦上最具攻击性,这表明脉冲谷物旋转中疾病风险增加.

科学领域:

植物病理学植物病理学
农业科学农业科学
菌类学菌类学是指菌类学.

背景情况:

虫虫 (Fusarium avenaceum) 导致豆类中的根腐,谷物中的虫 (Fusarium head blight) 导致谷物中的虫.
在脉冲谷物旋转中观察到更高的F. avenaceum丰度.
农作物轮换对F. avenaceum侵略性的影响尚不清楚.

研究的目的:

为了评估F. avenaceum在不同宿主上的攻击性,从不同轮作物 (豆类,小麦,豆) 中分离出来.
要确定作物来源是否影响F. avenaceum的致病性.
评估后续作物中疾病发病率增加的风险.

主要方法:

从豆,小麦和豆中收集了F. avenaceum的分离物.
孤立的攻击性被测试在豆和豆的根腐和硬小麦的头部病.
侵略性根据疾病严重程度进行分类.

主要成果:

大多数来自豆,小麦和豆的分离物分别对豆和豆表现出高,中等至高和低的攻击性.
在所有测试的主体中,豆衍生分离物始终更具侵略性.
在硬小麦上,在豆类和小麦衍生分离物之间没有发现显著的攻击性差异.

结论:

F. avenaceum 的侵略性受其宿主作物来源的影响.
在谷物轮换中包括豆可能会增加后续小麦作物中F. avenaceum头部病的风险.
了解孤立的侵略性对于在轮换系统中管理脉和谷物疾病至关重要.

The Roles of Bacteria and Fungi in Plant Nutrition

Plants have the impressive ability to create their own food through photosynthesis. However, plants often require assistance from organisms in the soil to acquire the nutrients they need to function correctly. Both bacteria and fungi have evolved symbiotic relationships with plants that help the species to thrive in a wide variety of environments.

Microbe-Plant Interactions

Microbe-Plant Interactions

Microbe-plant interactions represent a dynamic spectrum of associations shaped by intricate chemical signaling. These interactions can be neutral, beneficial, or detrimental, and profoundly influence plant physiology, growth, and ecosystem function. The plant microbiome, comprising bacteria, fungi, archaea, protists, and viruses, plays a pivotal role in mediating these effects through surface colonization, internal colonization, or systemic symbiosis.Mutualistic associations, particularly with...
