Abstract:
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.
