Comparative Genomic Analysis Reveals the Mechanism Driving the Diversification of Plastomic Structure in Taxaceae Species

open access: yesFrontiers in Genetics, 2020
Inverted repeat (IR) regions in the plastomes from land plants induce homologous recombination, generating isomeric plastomes. While the plastomes of Taxaceae species often lose one of the IR regions, considerable isomeric plastomes were created in ...
