Complete mitogenome assembly of Selenicereus monacanthus revealed its molecular features, genome evolution, and phylogenetic implications.

ABSTRACT:

Background

Mitochondria are the powerhouse of the cell and are critical for plant growth and development. Pitaya (Selenicereus or Hylocereus) is the most important economic crop in the family Cactaceae and is grown worldwide, however its mitogenome is unreported.

Results

This study assembled the complete mitogenome of the red skin and flesh of pitaya (Selenicereus monacanthus). It is a full-length, 2,290,019 bp circular molecule encoding 59 unique genes that only occupy 2.17% of the entire length. In addition, 4,459 pairs of dispersed repeats (≥ 50 bp) were identified, accounting for 84.78% of the total length, and three repeats (394,588, 124,827, and 13,437 bp) mediating genomic recombination were identified by long read mapping and Sanger sequencing.
