概括

这项研究确定了四种宏观真菌物种中的二十种新型病毒和病毒片段. 这些真菌中的mycovirus丰富度低于植物病原性真菌,为真菌病毒组提供了新的见解.

科学领域:

菌类学和病毒学.
土壤生态学和真菌生物学
基因组学和生物信息学

背景情况:

大菌对于陆地生态系统中的土壤元素循环至关重要.
真菌病毒在线状真菌中普遍存在,可以影响宿主生理学.
宏病毒的组成和进化动态在很大程度上仍未被探索.

研究的目的:

描述四种宏真菌物种的病毒组:Trametes versicolor,Coprinellus micaceus,Amanita strobiliformis和Trametes hirsuta. 这四种真菌物种的病毒组包括:
调查已识别的真菌病毒的遗传关系和丰富性.
为了比较宏和植物病原菌之间的mycovirus多样性和丰富性.

主要成果:

在四种宏观真菌物种中对二十种新型病毒或病毒片段进行了表征.
病毒结合体的原始遗传学分类为十个病毒家族/序列,包括广泛分布的两样病毒.
与广泛宿主植物病原菌 (*Ascomycota*) 相比,研究的宏真菌 (*Basidiomycota*) 中的真菌病毒的丰度和多样性明显较低.

结论:

这项研究首次使用元转录学证明了Amanita strobiliformis*,Coprinellus micaceus*,Trametes hirsute*和Trametes versicolor*中的多种真菌病毒.
这些发现扩大了对宏菌中的真菌病毒多样性和组成的理解.
这项研究为真菌病毒学领域提供了有价值的数据,突出了真菌群体之间的病毒载荷差异.

Evolutionary Relationships through Genome Comparisons

Evolutionary Relationships through Genome Comparisons

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...

Gene Evolution - Fast or Slow?

Gene Evolution - Fast or Slow?

The genomes of eukaryotes are punctuated by long stretches of sequence which do not code for proteins or RNAs. Although some of these regions do contain crucial regulatory sequences, the vast majority of this DNA serves no known function. Typically, these regions of the genome are the ones in which the fastest change, in evolutionary terms, is observed, because there is typically little to no selection pressure acting on these regions to preserve their sequences.
In contrast, regions which code...
