abstract = {The monophyly of tribe Arundinarieae (the temperate woody bamboos) has been unequivocally recovered in previous molecular phylogenetic studies. In a recent phylogenetic study, ten major lineages in Arundinarieae were resolved based on eight non-coding plastid regions, which conflicted significantly with morphological classifications both at the subtribal and generic levels. Furthermore, the in-depth relationships among and within the ten lineages remain unclear. In order to further unravel the evolutionary history of Arundinarieae, we used the nuclear GBSSI gene sequences along with those of eight plastid regions for phylogeny reconstruction, with an emphasis on Chinese species. The results of the plastid analyses agreed with the previous study, whereas thirteen primary clades were revealed in the GBSSI phylogeny which were more resolved at the generic level than the plastid phylogeny. Our analyses also revealed many inconsistencies between the plastid DNA and the nuclear GBSSI trees. These results implied that the nuclear genome and the plastid genome had different evolutionary trajectories in Arundinarieae. The patterns of incongruence suggested that lack of informative characters, incomplete lineage sorting, and/or hybridization (introgression) could be the causes. Seven putative hybrid species were hypothesized, four of which were discussed in detail on the basis of topological incongruence, chromosome numbers, morphology, and distribution patterns, and those taxa probably resulted from homoploid hybrid speciation. Overall, our study indicated that the tribe Arundinarieae had a complex evolutionary history.}
