概括
树状菌根真菌和Epichloë内植物可以相互作用,使牧场草受益,但AM真菌可能会增加秋季军的吸引力. 这些共生生物会影响昆虫攻击下的植物防御激素.
科学领域:
- 植物与微生物的相互作用
- 植物与昆虫的相互作用
- 生态生态学 生态生态学
背景情况:
- 寒冷季节的草是树枝状菌根 (AM) 和Epichloë内菌的宿主,赋予植物耐药性.
- 这些共生体对宿主植物防御昆虫食草动物的综合作用尚不清楚.
研究的目的:
- 研究AM真菌,Epichloë内生植物和秋季军 (FAW) 对Lolium perenne的单独和联合作用.
- 评估对植物生长,防御酶,激素度和FAW行为的影响.
主要方法:
- 玻璃屋实验使用Lolium perenne,Acaulospora delicata (AM真菌),Epichloë内植物和Spodoptera frugiperda (FAW). 这是一个非常好的实验.
- 测量包括植物生物量,菌根殖民率,防御酶活性,荷尔蒙水平和FAW嗅觉仪测试.
主要成果:
- 亚米真菌和与Epichloë的共同殖民增加了地面上的生物量;FAW减少了它.
- 无论是Epichloë还是FAW都降低了菌根菌的殖民率.
- 植被AM的植物对FAW幼虫更有吸引力.
- 在FAW攻击下,相互作用增加了斯蒙酸和降低了西醇活性.
- 没有任何共生体影响了FAW的生长速度.
结论:
- 不管是FAW,AM真菌对Lolium perenne的生长有积极的影响,比Epichloë内植物更重要.
- 亚米真菌可以增加植物对FAW草食菌的敏感性.
- 在昆虫草食过程中,共生体相互作用调节植物防御激素配置文件.

Plants often form mutualistic relationships with soil-dwelling fungi or bacteria to enhance their roots’ nutrient uptake ability. Root-colonizing fungi (e.g., mycorrhizae) increase a plant’s root surface area, which promotes nutrient absorption. While root-colonizing, nitrogen-fixing bacteria (e.g., rhizobia) convert atmospheric nitrogen (N2) into ammonia (NH3), making nitrogen available to plants for various biological functions. For example, nitrogen is essential for the...

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.
