The first mitogenome of Lauraceae (Cinnamomum chekiangense)

Changwei Bi et al. Plant Divers. .

Abstract

•The first reported mitochondrial genome (Cinnamomum chekiangense) of the Lauraceae family.•The mitogenome of C. chekiangense retains almost all of the ancestral protein-coding genes and has the highest RNA editing number in angiosperms.•Both of the plastid and mitochondrial phylogenetic trees support the magnoliids as a sister group of monocots and eudicots.

(A) The Circular mitogenome map of Cinnamomum chekiangense. Asterisks beside genes represent intron-containing genes. Genes with different functions are depicted using different colors. (B) Schematic representation of the collinearity among five magnoliid mitogenomes. The blue and red dots represent the direct and inverted syntenic regions, respectively. (C) Intron content among 11 seed plant mitogenomes. Blue, intron is absent; Yellow, intron is cis-splicing; Red, intron is trans-splicing. (D) Characteristic of RNA editing sites across all PCGs in the mitogenome of C. chekiangense. PCGs with different functions are depicted using different colors. (E) The phylogenetic relationships of 24 plant species based on mitochondrial PCGs (left) and complete plastome sequences (right). Funaria hygrometrica and Marchantia paleacea were used as outgroup. Numbers on each branch are bootstrap support values. Colors indicate the groups for each species.
