Reconfiguration of the plastid genome in Lamprocapnos spectabilis: IR boundary shifting, inversion, and intraspecific variation.

ABSTRACT: We generated a complete plastid genome (plastome) sequence for Lamprocapnos spectabilis, providing the first complete plastome from the subfamily Fumarioideae (Papaveraceae). The Lamprocapnos plastome shows large differences in size, structure, gene content, and substitution rates compared with two sequenced Papaveraceae plastomes. We propose a model that explains the major rearrangements observed, involving at least six inverted repeat (IR) boundary shifts and five inversions, generating a number of gene duplications and relocations, as well as a two-fold expansion of the IR and miniaturized small single-copy region. A reduction in the substitution rates for genes transferred from the single-copy regions to the IR was observed. Accelerated substitution rates of plastid accD and clpP were
