Beyond conservation: the landscape of chloroplast genome rearrangements in angiosperms

open access: yesNew Phytologist, EarlyView.
Summary Chloroplast genomes (plastomes) have long been considered structurally conserved, but recent sequencing efforts have uncovered pervasive rearrangements that challenge this assumption. This review catalogues the main types of plastome modifications: large and small inversions; insertions and deletions (indels); gene and intron losses; horizontal
