概括
选择性内共生生物在野生虫物种中很常见,超过一半的被研究物种含有这些微生物. 它们的流行程度在虫养策略之间有所不同,这凸显了它们的生态意义.
科学领域:
- * 昆虫微生物学 昆虫微生物学
- * 生态相互作用
- * 虫生物学 虫生物学
背景情况:
- * 选择性内共生生物是生活在昆虫内部的微生物,但对生存并不必不可少.
- *研究主要集中在作物害虫上,因此自然虫种群研究不足.
- *了解内生生物的流行是理解虫生态学的关键.
研究的目的:
- * 调查非商业虫物种中八种常见的学科内生生物的发生情况.
- * 为了确定虫养策略 (寡与单) 或倾向是否影响内生生物的存在.
- *为未来研究自然虫群体内共生体功能建立基线.
主要方法:
- *对来自106个物种的437个虫样本进行了选,以检测八种常见的学科内生生物的存在.
- *分析了内生生体存在与虫种类的食习惯和协会之间的相关性数据.
- * 进行了荷兰第一个同类综合性研究.
主要成果:
- *在53%的被调查虫物种中检测到一个或多个可选性内共生生物.
- * Oligophagous 类物种被发现比单食物种更频繁地携带可选性内共生体.
- * 没有观察到护和选择性内生生物的存在之间有显著的相关性.
结论:
- * 选择性内共生生物在天然虫群体中广泛存在.
- * 该研究为荷兰提供了基础数据,识别了各种虫物种中常见的内共生生物.
- *需要进一步的研究来阐明这些内共生体的功能作用及其对虫社区动态的影响.

Symbiotic relationships are long-term, close interactions between individuals of different species that affect the distribution and abundance of those species. When a relationship is beneficial to both species, this is called mutualism. When the relationship is beneficial to one species but neither beneficial nor harmful to the other species, this is called commensalism. When one organism is harmed to benefit another, the relationship is known as parasitism. These types of relationships often...

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.
