Characterization of the complete mitochondrial genome of biocontrol yeast Sporobolomyces sp. (Sporidiobolales: Sporidiobolaceae) with phylogenetic analysis

Abstract

In this study, we obtained the complete mitochondrial genome of Sporobolomyces sp. using nextgeneration sequencing. The complete mitochondrial genome of Sporobolomyces sp. contained 15 protein-coding genes (PCG), two ribosomal RNA (rRNA) genes, and 25 transfer RNA (tRNA) genes. The total length of the Sporobolomyces sp. mitochondrial genome is 26,430 bp, and the GC content of the mitochondrial genome is 39.32%. Phylogenetic analysis based on combined mitochondrial gene dataset indicated that the mitochondrial genome of Sporobolomyces sp. exhibited a close relationship with that of Rhodotorula mucilaginosa.

The complete mitochondrial genome sequence of the Metschnikowia bicuspidata (Metschnikoff, 1884), an emerging pathogen of ‘milky disease’ in Chinese mitten crab

“…Its nucleotide composition was as follows: A, 39.1%; C, 11.8%; G, 13.5%; T, 35.6%, with a high AT content of 74.7% which was higher than other kinds of yeast, such as Sporobolomyces sp and Cystobasidium sp (Huang et al. 2020 ; Liu and Wang 2020 ). The circular mitogenome of this yeast includes two rRNAs (16S rRNA and 12S rRNA), 23 tRNAs (tRNA-Ser, tRNA-Thr, tRNA-Val, tRNA-Cys, tRNA-Leu, tRNA-Glu, tRNA-His, tRNA-Met, tRNA-Tyr, tRNA-Asp, tRNA-Arg, tRNA-Phe, tRNA-Gly, tRNA-Asn, tRNA-Pro, tRNA-Lys, tRNA-Ile, tRNA-Gln, tRNA-Ala, and tRNA-Sec) and 13 protein-coding genes (PCGs).…”
