Repetitive Elements, Sequence Turnover and Cyto-Nuclear Gene Transfer in Gymnosperm Mitogenomes
Hui Liu 1, Wei Zhao 2, Ren-Gang Zhang 3, Jian-Feng Mao 1, Xiao-Ru Wang 1 2
...Here, we report the complete mitogenome sequence of Platycladus orientalis (Cupressaceae)...Our phylogenetic analysis supports a sister group relationship of Cupressophytes and Gnetophytes; both groups are unique in that they lost 8-12 protein-coding genes, of which 4-7 intact genes are likely transferred to nucleus. These two clades also show accelerated and highly variable substitution rates relative to other gymnosperms...
