Structural variation and evolutionary dynamics of plastid genomes in the subgenus Lychnis (Silene, Caryophyllaceae): insights from genome rearrangements and substitution rates.

BACKGROUND: Plastid genomes (plastomes) in land plants typically retain a conserved quadripartite structure; yet some angiosperm lineages exhibit extensive structural instability and accelerated sequence evolution. Here, we present a comparative plas…
