Mitochondrial DNA A DNA Mapp Seq Anal. 2016 Sep;27(5):3246-7. doi: 10.3109/19401736.2015.1007367. Epub 2015 Jan 29.
The complete mitochondrial genome of the nematophagous fungus Acremonium implicatum is reported for the first time. The genome is concatenated with 22,367 bp in length, encoding 13 protein-coding genes, 2 ribosomal RNA genes and a set of 17 transfer RNA genes. The synteny analysis reveals that 50.35% of A. implicatum mitochondrial sequences matched to 48.21% of Acremonium chrysogenum mitochondrial sequences with 85.68% identity. Two proteins of cox3 and nad6, as well as seven tRNAs are lost in A. implicatum mitogenome compared to A. chrysogenum mitogenome. The gene orders in A. implicatum and A. chrysogenum mitogenome is different, which is mainly due to the location of nad4 and cox2. In addition, one transposition event related to tRNAs is identified in these two mitogenomes. This study may provide valuable mitochondrial information for research on A. implicatum and facilitate the study of mitochondrial evolution.
首次报道了线虫捕食真菌隐间座壳孢的完整线粒体基因组。该基因组长度为22367bp，串联排列，编码13个蛋白质编码基因、2个核糖体RNA基因和一组17个转运RNA基因。共线性分析表明，隐间座壳孢线粒体序列的50.35%与产黄青霉线粒体序列的48.21%匹配，同一性为85.68%。与产黄青霉线粒体基因组相比，隐间座壳孢有丝分裂基因组中cox3和nad6这两种蛋白质以及7个tRNA缺失。隐间座壳孢和产黄青霉线粒体基因组中的基因顺序不同，这主要是由于nad4和cox2的位置。此外，在这两个线粒体基因组中发现了一个与tRNA相关的转座事件。本研究可能为隐间座壳孢的研究提供有价值的线粒体信息，并有助于线粒体进化的研究。
