概括

虫病显著改变草植物内生菌微生物群落. 病原体感染减少了细菌和真菌的多样性,减少了有益的微生物,同时增加了Fusarium的丰富性.

科学领域:

植物病理学植物病理学
微生物学微生物学
生态生态学生态生态学

背景情况:

内生菌微生物影响植物健康和病原体耐药性.
草内生菌微生物群落上的Fusarium枯的影响仍然未被充分研究.

研究的目的:

为了研究在草植物体内细菌和真菌内生菌群体在Fusarium感染后的变化.
分析这些社区的多样性,结构和组成,在健康的植物和受感染的植物中.

主要方法:

细菌群落的16S rRNA基因扩增序列测序.
对于真菌群体的内部转录间隔器 (ITS) rRNA基因扩增序列.
在健康和被菌感染的草的根,茎和叶子中对内菌群的比较分析.

主要成果:

菌显著改变了内菌细菌和真菌群体.
与健康的人相比,感染区的微生物多样性较低.
有益的属 (例如,Bacillus,Trichoderma) 的相对丰度下降,而在受感染的植物中,Fusarium的丰度增加.

结论:

病原体的入侵对草内生菌微生物群落产生了深远的影响.
这些发现为通过微生物洞察力了解和管理草枯疾病提供了基础.

关键词:

细菌社区是一种细菌社区.菌社区是真菌社区.微生物组是一个微生物组.植物病原体的病原体草 Fusarium 枯的疾病

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.
