Abstract

The genome size of an organism varies from species to species. The C-value paradox enigma is a very complex puzzle with regards to vast diversity in genome sizes in eukaryotes. Here we reported the detailed genomic information of 172 fungal species among different fungal genomes and found that fungal genomes are very diverse in nature. In fungi, the diversity of genomes varies from 8.97 Mb to 177.57 Mb. The average genome sizes of Ascomycota and Basidiomycota fungi are 36.91 and 46.48 Mb respectively. But higher genome size is observed in Oomycota (74.85 Mb) species, a lineage of fungus-like eukaryotic microorganisms. The average coding genes of Oomycota species are almost doubled than that of Acomycota and Basidiomycota fungus.

摘要

生物体的基因组大小因物种而异。C值悖论之谜是一个关于真核生物基因组大小巨大差异的非常复杂的谜题。在这里,我们报告了172种真菌在不同真菌基因组中的详细基因组信息,发现真菌基因组在本质上非常多样。在真菌中,基因组的多样性从897万个碱基对到1.7757亿个碱基对不等。子囊菌门和担子菌门真菌的平均基因组大小分别为3691万个碱基对和4648万个碱基对。但在卵菌纲(7485万个碱基对)物种中观察到更大的基因组大小,卵菌纲是一类类似真菌的真核微生物。卵菌纲物种的平均编码基因几乎是子囊菌门和担子菌门真菌的两倍。
