概括

野生草的全基因组复制改变了叶子细菌和根/叶子真菌的组成,但没有改变细菌的多样性. 这些微生物组变化因植物基因型和微生物群落而异,突出显示了基因组重复对植物微生物组的直接影响.

科学领域:

植物生物学植物生物学
微生物组研究的研究.
基因组学就是基因组学.

背景情况:

整个基因组的重复 (新聚化) 可以快速改变植物的表型.
植物器官的表型变化可能会影响与微生物群落的相互作用.
人们对基因组重复如何影响微生物社区的整体多样性和组成的理解有限.

研究的目的:

为了研究 autotetraploidy 对野生草 (Fragaria vesca) 中的突发性细菌和真菌群落的多样性和组成的影响.
为了确定基因组重复是否影响根和叶子中的微生物群落.
为了探索 ploidy 诱导的表型变化和微生物组变化之间的关系.

主要方法:

一个常见的花园实验,使用来自13种基因型的合成自带四体和双体野生草 (Fragaria vesca).
从根和叶子中测序菌细菌和真菌.
微生物群落的表征和相关的叶子功能特征.

主要成果:

自动化并没有影响根或叶子中的细菌α多样性.
叶子上的真菌多样性以基因型依赖的方式受到自体化的影响.
自动化重组了叶子细菌群体的组成,并影响了这两个器官中的真菌群体组成,其中Sphingomonas和Trichoderma是关键分类.
叶片大小的Ploidy诱导的变化与细菌社区的转移相关,但不是真菌社区.

结论:

由于基因组重复,植物微生物组发生了直接的变化.
基因组重复对微生物群的影响取决于宿主基因型和特定的微生物群落 (细菌与真菌).
为了验证这些发现,需要在自然环境中进行进一步的研究.

Formation of Species

Formation of Species

Speciation describes the formation of one or more new species from one or sometimes multiple original species. The resulting species are discrete from the parent species, and barriers to reproduction will typically exist. There are two primary mechanisms, speciation with and without geographic isolation—allopatric and sympatric speciation, respectively.

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.

Genetics of Speciation

Genetics of Speciation

Speciation is the evolutionary process resulting in the formation of new, distinct species—groups of reproductively isolated populations.
