Complete organelle genomes of Korean fir, Abies koreana and phylogenomics of the gymnosperm genus Abies using nuclear and cytoplasmic DNA sequence data.

ABSTRACT: Abies koreana E.H.Wilson is an endangered evergreen coniferous tree that is native to high altitudes in South Korea and susceptible to the effects of climate change. Hybridization and reticulate evolution have been reported in the genus; therefore, multigene datasets from nuclear and cytoplasmic genomes are needed to better understand its evolutionary history. Using the Illumina NovaSeq 6000 and Oxford Nanopore Technologies (ONT) PromethION platforms, we generated complete mitochondrial (1,174,803 bp) and plastid (121,341 bp) genomes from A. koreana. The mitochondrial genome is highly dynamic, transitioning from cis- to trans-splicing and breaking conserved gene clusters. In the plastome, the ONT reads revealed two structural conformations of A. koreana. The short inverted repeats (1186 bp
