Abstract

The complete mitogenomes of Puccinia striiformis f. sp. tritici (Pst) CY32 and P. recondita f. sp. tritici (Pt) HnZU18-3, two destructive rust fungi in wheat, are sequenced and determined. Their circular mitogenomes are 102,521 bp and 77,894 bp in length and contain 24 and 23 tRNA genes for Pst and Pt, respectively, and both consist of 14 protein-coding genes located on the same strand. Phylogenetic analysis revealed the phylogenetic relationships of Pst and Pt based on mitogenomes conform to the previous identification in genomic level.

Keywords: Puccinia striiformis; Puccinia tritici; Rust fungi; mitochondrial genome.
