New insights into the phylogenetic relationships within the Lauraceae from mitogenomes.

ABSTRACT:

Background

The family Lauraceae is subdivided into six main lineages: Caryodaphnopsideae, Cassytheae, Cryptocaryeae, Hypodaphnideae, Laureae, and Neocinnamomeae. However, phylogenetic relationships among these lineages have been debatable due to incongruence between trees constructed using nuclear ribosomal DNA (nrDNA) sequences and chloroplast (cp) genomes. As with cp DNA, the mitochondrial (mt) DNA of most flowering plants is maternally inherited, so the phylogenetic relationships recovered with mt genomes are expected to be consistent with that from cp genomes, rather than nrDNA sequences.

Results

The mitogenome of Machilus yunnanensis, with a length of 735,392 bp, has a very different genome size and gene linear order from previously published magnoliid mitogenomes. Phyl
