概括
该研究重新分类了真菌,根据形态和遗传分析将Arachniotus和Sphaerosporium属合并为Sporendonema. 这一分类学修订确立了四种新的组合,并引入了一种新物种,Sporendonema isthmoides.
科学领域:
- 菌类学 菌类学是指菌类学.
- 菌类分类法 菌类分类法 菌类分类法
- 分子遗传学分子遗传学
背景情况:
- 1827年建立的Sporendonema属最初是由S.casei定义的,S.casei是一种常见于奶酪上的红色菌.
- 其他物种,如Sphaerosporium equinum也与奶酪环境有关,尽管最近的发现表明更广泛的息地.
- 相关的属,如Arachniotus和Hormiscium aurantiacum,也与奶酪有关,促使进行了分类学调查.
研究的目的:
- 对Sporendonema和Sphaerosporium属进行全面的分类学调查,包括相关的种类.
- 为了澄清这个真菌群体内的遗传关系和物种界限.
- 建立与奶酪相关的真菌和其他真菌的准确分类和命名法.
主要方法:
- 宏观和微观形态学的比较分析.
- 生理学评估包括盐分耐受性,在不同温度下生长速度,素降解,细胞质和脂解活性.
- 使用核糖体内部转录间隔器 (ITS) 区域,D1-D2大亚单元和部分β-蛋白基因序列的多位基因分析.
主要成果:
- 形态和遗传学数据证实了Sporendonema,Arachniotus和Sphaerosporium是同源的.
- 阿拉奇尼奥托斯和斯菲洛斯波里乌姆被简化为斯波伦多尼玛的同义词.
- 在Sporendonema属内确立了四种新的组合,并指定了乳型和表型.
- 两种以前被识别为Sphaerosporium equinum的菌株,从非奶酪基质中分离出来,在遗传学上是不同的,并被描述为一种新物种,Sporendonema isthmoides.
结论:
- 亚拉奇诺图斯 (Arachniotus) 和斯菲洛斯波里亚 (Sphaerosporium) 属是斯波伦多内马 (Sporendonema) 的同义词,因此需要进行分类学修订.
- 该研究为几种真菌物种提供了精细的分类,增强了对Sporendonema属的理解.
- 描述了一种新物种Sporendonema isthmoides,扩大了这个真菌群体内的已知多样性.

Formation of Species
39.3K
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.

Symbiosis
27.9K
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...

Phylogeny
44.0K
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.

Taxonomy
74.1K
Taxonomy is the science of defining and naming groups of biological organisms based on shared characteristics. It uses a hierarchy of increasingly inclusive categories with Latin names. The smallest units of taxonomy, species and genus, are used to assign a formal, taxonomic name to each species in a system. This classification system, referred to as binomial nomenclature, was formalized by Carolus Linnaeus in the 18th century.

Evolutionary 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...
