The number of chloroplast genomes of bamboos was growing, with an emphasis on Old World woody ***, the chloroplast genomes of neotropical woody bamboos had rarely been *** pinpoint the pattern of chloroplast genome evolution within neotropical-paleotropical bamboos, we fully characterized one new chloroplast genome, for the woody bamboo Guadua *** chloroplast genome of *** was 135,332 bp long and was composed of an 82,840 bplarge single-copy (LSC) region, a 12,898 bp small single-copy (SSC) region, and a pair of 19,797 bp inverted repeats (IRs).Comparative analyses revealed marked conservation of gene contents and sequence evolutionary rates between neotropical and paleotropical woody *** neotropical herbaceous bamboo differed from woody bamboos in IR/SSC boundary due to slightly contracted IR and faster substitution *** chloroplast genome of *** was similar in size to that of neotropical herbaceous bamboo but, notably, was ~3k bp smaller than that of paleotropical woody *** in genome size were correlated with various lengths of intergenic spacers caused by large-fragment insertion and *** analyses of 53 taxa yielded an identical tree topology as in preceding *** time estimation suggested that most genera of bamboos diverged in the Miocene and that speciation events of extant species happened in or after the Pliocene.
