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.
灰绿犁头霉和寄生被孢霉构成了一个通用的实验系统，用于研究毛霉目宿主与其融合寄生虫之间的水平基因转移。灰绿犁头霉的线粒体基因组长度约为63 kb，GC含量为28%。寄生被孢霉的线粒体基因组更大，为83 kb，含有31%的GC碱基对。这些线粒体DNA包含标准的真菌线粒体基因集、小亚基和大亚基rRNA，以及核糖核酸酶P RNA。比较接合菌的线粒体基因组发现，寄生被孢霉中归巢内切酶基因的数量异常多，这证实了内含子元件的移动性独立于宿主 - 寄生虫相互作用。
