The mitochondrial genome of Pinus sylvestris var. mongolica Litv. (Pinales: Pinaceae)
Abstract
We used Illumina and Nanopore data to complete the sequencing and assembly of mitochondrial genome of Pinus sylvestris var. mongolica, an important coniferous tree species adapted to arid and semi-arid ecosystems. The genome comprises 2,273,603 bp with a GC content of 46.80% (A: 26.56%, T: 26.65%, C: 23.47%, G: 23.33%) and features both molecule 1 and molecule 2 components. It encodes 39 protein-coding, 11 tRNA, and three rRNA genes, with notable gene duplications and intron-rich regions. Phylogenetic analysis places P. sylvestris var. mongolica within Pinus. Under the limited set of publicly available Pinaceae mitogenomes, Pinus and Cathaya are adjacent in the tree
