摘要

摘要:蓝靛草(Absidia glauca)和寄生寄生物(Parasitella parasitica)构成了一个多功能的实验系统，用于研究mucoralean宿主与其融合寄生物之间的水平基因转移。青花孤杉线粒体长约63 kb, GC含量为28%。寄生蜂的线粒体较大，为83 kb，含有31%的GC碱基对。这些mtdna包含标准的真菌线粒体基因集，小亚基和大亚基rnas，以及核糖核酸酶P RNA。通过对接合菌线粒体的比较，发现寄生疟原虫中有大量的归巢内切酶基因，证实了独立于宿主-寄生虫相互作用的内含子元件的移动性。

The fate of mitochondria after infection of the Mucoralean fungus Absidia glauca by the fusion parasite Parasitella parasitica: comparison of mitochondrial genomes in zygomycetes

Abstract Absidia glauca and Parasitella parasitica constitute a versatile experimental system for studying horizontal gene transfer between a mucoralean host and its fusion parasite. The A. glauca chondriome has a length of approximately 63 kb and a GC content of 28%. The chondriome of P. parasitica is larger, 83 kb, and contains 31% GC base pairs. These mtDNAs contain the standard fungal mitochondrial gene set, small and large subunit rRNAs, plus ribonuclease P RNA. Comparing zygomycete chondriomes reveals an unusually high number of homing endonuclease genes in P. parasitica, substantiating the mobility of intron elements independent of host-parasite interactions.

期刊介绍： Mitochondrial DNA Part A publishes original high-quality manuscripts on physical, chemical, and biochemical aspects of mtDNA and proteins involved in mtDNA metabolism, and/or interactions. Manuscripts on cytosolic and extracellular mtDNA, and on dysfunction caused by alterations in mtDNA integrity as well as methodological papers detailing novel approaches for mtDNA manipulation in vitro and in vivo are welcome. Descriptive papers on DNA sequences from mitochondrial genomes, and also analytical papers in the areas of population genetics, phylogenetics and human evolution that use mitochondrial DNA as a source of evidence for studies will be considered for publication. The Journal also considers manuscripts that examine population genetic and systematic theory that specifically address the use of mitochondrial DNA sequences, as well as papers that discuss the utility of mitochondrial DNA information in medical studies and in human evolutionary biology.
