Complete chloroplast genomes of three <i>Pleurozia</i> species and comparative analyses with <i>P. purpurea</i>: codon usage bias and phylogeny.

ABSTRACT: The liverwort genus Pleurozia, a morphologically specialized bryophyte group, holds unique taxonomic and evolutionary significance. This study sequenced and assembled the chloroplast genomes of three Pleurozia species (P. acinosa, P. gigantea, and P. subinflata), with genome sizes of 118,233 bp, 118,423 bp, and 118,304 bp, respectively. All three genomes exhibit the typical quadripartite structure. Comparative genomics analyses, including the genome of P. purpurea, revealed high conservation in genome size, gene content, and inverted repeat (IR) boundaries. Coding regions were more conserved than noncoding and intronic regions, suggesting the potential of the latter as molecular markers. The IR regions also displayed significantly lower sequence di
