Two linear mitochondrial plasmids called pFOXC1 and pFOXC2 from the fungus Fusarium oxysporum were previously described. DNA sequence comparisons indicated that the derived amino acid sequences of both plasmids exhibit similarity to the reverse transcriptase of the Mauriceville and Varkud plasmids of Neurospora spp. The derived amino acid sequence of pFOXC2 has 51% similarity and 32% identity to the Neurospora reverse transcriptase; sequence similarity was greatest for seven blocks of amino acids that are conserved in reverse transcriptases from a wide range of biological sources. Northern analysis suggests that full-length RNAs corresponding to the plasmids are found in representative isolates.
之前已经描述过来自尖孢镰刀菌的两个线性线粒体质粒，分别称为pFOXC1和pFOXC2。DNA序列比较表明，这两个质粒推导的氨基酸序列与脉孢菌属的莫里斯维尔质粒和瓦尔库德质粒的逆转录酶具有相似性。pFOXC2推导的氨基酸序列与脉孢菌逆转录酶的相似性为51%，同一性为32%；对于来自广泛生物来源的逆转录酶中保守的七个氨基酸区域，序列相似性最大。Northern分析表明，在代表性分离株中发现了与这些质粒相对应的全长RNA。
