The complete mitochondrial genome of Pseudofabraea citricarpa (Dermateaceae: Helotiales) causing Citrus target spot

Abstract

AbstractPseudofabraea citricarpa (Dermateaceae: Helotiales) is known as a significant pathogen causing Citrus target spot disease and results in profound yield loss. In the present study, the complete mitochondrial genome (mitogenome) determined based on next-generation sequencing technology. The circular mitogenome (56,935 bp) comprised 14 conserved protein-coding genes (PCGs), 16 ORFs, two ribosomal RNA genes (rns and rnl), one non-coding RNA gene (rnpB), one ribosomal protein S3 (rps3) and 28 transfer RNA (tRNA) genes. The overall base composition is as follows: 36.08% A, 35.25% T, 13.04% C, and 15.63% G, with a GC content of 28.70%. The phylogenetic analysis shows that P. citricarpa, belonging to Dermateaceae, forms a separate clade and is sister to Sclerotiniaceae. The mitogenome of P. citricarpa reported in this study provides more molecular data for further research on the evolutionary relationships of Helotiales.
