The size diversity of the Pteridaceae family chloroplast genome is caused by overlong intergenic spacers [PDF]

open access: yesBMC Genomics
Background While the size of chloroplast genomes (cpDNAs) is often influenced by the expansion and contraction of inverted repeat regions and the enrichment of repeats, it is the intergenic spacers (IGSs) that appear to play a pivotal role in determining

Adaptive evolution and co-evolution of chloroplast genomes in Pteridaceae species occupying different habitats: overlapping residues are always highly mutated [PDF]

open access: yesBMC Plant Biology, 2023
Background The evolution of protein residues depends on the mutation rates of their encoding nucleotides, but it may also be affected by co-evolution with other residues.
