概括
培养真菌的白拥有多种不同的Xylaria真菌. 科特迪瓦的一项研究揭示了18种新的Xylaria物种,这表明非洲真菌共生物种多样性被严重低估.
科学领域:
- 菌类学 菌类学是指菌类学.
- 昆虫学 昆虫学是一门学科.
- 进化生物学 进化生物学
背景情况:
- 培养真菌的白 (Blattodea类) 宿主Xylaria真菌,在非洲比亚洲的宿主多样性更高.
- 理论预测共生生物多样性反映了宿主多样性,但从非洲 (3) 描述的Xylaria物种比亚洲 (17) 描述的更少.
- 这种差异表明非洲白相关的Xylaria的样本不足.
研究的目的:
- 在非洲调查与白相关的Xylaria的多样性.
- 为了测试假设非洲西拉利亚多样性被低估的假设.
主要方法:
- 从科特迪瓦的20个白殖民地收集了34个Xylaria分离物.
- 对这些分离物以及其他278个Xylaria标本进行了多位置的遗传学分析.
- 包括外组标本用于强大的基因排列.
主要成果:
- 从非洲样本中鉴定出18种假定新型西拉里亚菌种.
- 证实了非洲低估了西拉利亚多样性的假设.
- 已证明的西拉里亚物种可以殖民各种白宿主的花园.
- 观察到单个白殖民地可以容纳多个Xylaria物种.
结论:
- 与非洲白相关的Xylaria多样性被严重低估.
- 实质性的真菌多样性仍然未被发现,特别是在非洲,考虑到甲属的样本采集有限.
- 齐拉里亚物种在真菌养殖白系统中表现出广泛的宿主殖民能力.

02:54Evolutionary Relationships through Genome Comparisons
5.7K
Genome comparison is one of the excellent ways to interpret the evolutionary relationships between organisms. The basic principle of genome comparison is that if two species share a common feature, it is likely encoded by the DNA sequence conserved between both species. The advent of genome sequencing technologies in the late 20th century enabled scientists to understand the concept of conservation of domains between species and helped them to deduce evolutionary relationships across diverse...

01:23Phylogeny
43.6K
Phylogeny is concerned with the evolutionary diversification of organisms or groups of organisms. A group of organisms with a name is called a taxon (singular). Taxa (plural) can span different levels of the evolutionary hierarchy. For instance, the group containing all birds is a taxon (comprising the class Aves), and the group of all species of daisies (the genus Bellis) is a taxon. Phylogenies can likewise include just one genus (i.e., depict species relationships) or span an entire kingdom.

02:40The Tree of Life - Bacteria, Archaea, Eukaryotes
32.1K
The “tree of life” describes the evolution of life and the evolutionary relationships between organisms. The root of the tree is the common ancestor to all life on Earth. All other species radiate from this point, much like the branches of a tree. The numerous tips of these branches on the tree of life represent every living, or extant, species. Extinct species, which are species that no longer exist, can be found towards the center of the tree. Currently, these organisms, both...
