概括

侵入性植物微生物组在本地和异国范围之间存在差异. 低叶微生物多样性和异国情调范围内的较高病原体丰富性支持入侵物种成功的敌人释放假设.

科学领域:

微生物生态学微生物生态学
植物病理学植物病理学
侵入性物种生物学侵入性物种生物学

背景情况:

植物入侵的成功受到微生物相互作用的影响,可能是通过敌人释放或增强的互惠关系.
高通量测序推进了微生物组研究,但很少有研究将入侵性植物微生物组与原生和异国情调范围进行比较.

研究的目的:

为了比较它的本地 (日本) 和异国 (佛罗里达州,美国) 范围之间的入侵性 * Ardisia crenata * 中的真菌和细菌群体.
通过分析病原体和相互的丰富性来测试敌人释放假设和增强的互惠主义假设.

主要方法:

从 *Ardisia crenata* 的叶子,根和土壤中提取DNA.
照明测序来分析真菌和细菌社区的组成和多样性.
在本地和异国范围之间比较微生物群落.

主要成果:

微生物群落的组成在植物组织 (叶子,根,土壤) 和地理范围之间有很大的差异.
外来范围的土壤显示出更高的微生物多样性,而叶子和根的内层多样性比本地范围更低.
本地范围内的叶子具有更多的病原菌;异国叶子具有更高的特定病原体的丰富性,已知会影响*A. crenata*.

结论:

植物相关的微生物群落,特别是叶子和根,是由植物本身塑造的.
在异国情调范围内减少的叶子病原体负载支持侵略性植物的敌人释放假设.
研究地面和地下微生物群落对于了解植物入侵至关重要.

The Roles of Bacteria and Fungi in Plant Nutrition

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.

Epiphytes, Parasites, and Carnivores

Epiphytes, Parasites, and Carnivores

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...
