Plastid genome evolution in a group of non-photosynthetic angiosperms (Orobanchaceae).
The plastid genome shows extensive conservation in size, structure, composition and rate of nucleotide substitution across land plants. Its composition, however, is not static showing a general trend towards losing genetic information or rearranging genes. Major changes in content and structure of the plastid genome occur in holoparasitic (non-photosynthetic parasitic) plants showing an extensive plastid genome reduction and considerable differences in gene content and functionality. Orobanche and related genera (Orobanchaceae) are a well suited system for conducting a broad comparative investigation, addressing, among others, whether genome reduction and restructuring as well as gene functionality and pseudogene formation follows general trends or rather evolves idiosyncratically and how the change from an autotrophic to a heterotrophic plants affects rate evolution.
