Mitochondria are semi-autonomous organelles with their own genome and crucial to cellular material and energy metabolism. Here, we report the complete mitochondrial genome of a lipid-producing basidiomycetous yeast Rhodotorula toruloides NP11. The mitochondrial genome of R. toruloides NP11 was assembled into a circular DNA molecule of 125937bp, encoding 15 proteins, 28 transfer RNAs, 2 ribosomal RNA subunits and 10 open reading frames with unknown function. The G + C content (41%) of the mitochondrial genome is substantially lower than that of the nuclear genome (62%) of R. toruloides NP11. Further reanalysis of the transcriptome data confirmed the transcription of four mitochondrial genes. The comparison of the mitochondrial genomes of R. toruloides NP11 and NBRC0880 revealed a significant genetic divergence. These data can complement our understanding of the genetic background of R. toruloides and provide fundamental information for further genetic engineering of this strain.

产脂酵母红酵母的完整线粒体基因组。

线粒体是具有自己基因组的半自主细胞器，对细胞物质和能量代谢至关重要。在这里，我们报告了产脂担子菌酵母红酵母NP11的完整线粒体基因组。R. toruloides NP11的线粒体基因组组装成一个125937bp的环状DNA分子，编码15个蛋白质、28个转移RNA、2个核糖体RNA亚基和10个功能未知的开放阅读框。线粒体基因组的 G + C 含量 (41%) 大大低于R. toruloides NP11的核基因组 (62%) 。对转录组数据的进一步重新分析证实了四种线粒体基因的转录。线粒体基因组的比较R. toruloides NP11 和 NBRC0880 显示出显着的遗传差异。这些数据可以补充我们对R. toruloides遗传背景的理解，并为该菌株的进一步基因工程提供基础信息。
