Rapid evolutionary divergence of diploid and allotetraploid Gossypium mitochondrial genomes.

ABSTRACT:

Background

Cotton (Gossypium spp.) is commonly grouped into eight diploid genomic groups and an allotetraploid genomic group, AD. The mitochondrial genomes supply new information to understand both the evolution process and the mechanism of cytoplasmic male sterility. Based on previously released mitochondrial genomes of G. hirsutum (AD₁), G. barbadense (AD₂), G. raimondii (D₅) and G. arboreum (A₂), together with data of six other mitochondrial genomes, to elucidate the evolution and diversity of mitochondrial genomes within Gossypium.

Results

Six Gossypium mitochondrial genomes, including three diploid species from D and three allotetraploid species from AD genome groups (G. thurberi D₁, G. davidsonii D_3-d an
