The Complete Chloroplast Genome of Guadua angustifolia and Comparative Analyses of Neotropical-Paleotropical Bamboos.

ABSTRACT: To elucidate chloroplast genome evolution within neotropical-paleotropical bamboos, we fully characterized the chloroplast genome of the woody bamboo Guadua angustifolia. This genome is 135,331 bp long and comprises of an 82,839-bp large 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 content and sequence evolutionary rates between neotropical and paleotropical woody bamboos. The neotropical herbaceous bamboo Cryptochloa strictiflora differs from woody bamboos in IR/SSC boundaries in that it exhibits slightly contracted IRs and a faster substitution rate. The G. angustifolia chloroplast genome is similar in size to that of neotropical herbaceous bamboos but is ~3
