竹子是全世界温带和热带森林中的大型多年生草本植物。存在两种一般的生长形式：经济和生态上重要的木本竹（Arundinarieae 和 Bambuseae 部落）和林下草本竹（Olyreae 部落）。所描述的 1400 多个物种之间的进化关系很难确定。对竹子质体（叶绿体）DNA 的比较分析揭示了三到五个显示出不同生物地理分布的主要谱系。跨部落和亚部落的分类单元采样并不完整，大多数公布的数据集包含相对少量的核苷酸特征。谱系之间的分支顺序通常缺乏支持，并且在不止一项研究中，草本竹在木本竹中形成了一个分支。在本文中，竹系统发育组使用 6.7 kb 的编码和非编码序列数据以及来自叶绿体基因组的 37 个微观结构特征，提出了迄今为止最完整的竹部落和亚部落的系统发育估计。评估数据的质量，以及长分支吸引的可能性、树中关键节点的角色冲突程度以及三个替代关系假设的合法性。已知四种主要质体谱系：温带木本、古热带木本、新热带木本和草本竹。木本竹被解析为与 Olyreae 相关的并系系，但 SH 测试不能拒绝木本物种（Arundinarieae + Bambuseae）的单系性。由爱思唯尔公司出版
Bamboos are large perennial grasses of temperate and tropical forests worldwide. Two general growth forms exist: the economically and ecologically important woody bamboos (tribes Arundinarieae and Bambuseae), and the understory herbaceous bamboos (tribe Olyreae). Evolutionary relationships among the 1400 + described species have been difficult to resolve with confidence. Comparative analysis of bamboo plastid (chloroplast) DNA has revealed three to five major lineages that show distinct biogeographic distributions. Taxon sampling across tribes and subtribes has been incomplete and most published data sets include a relatively small number of nucleotide characters. Branching order among lineages is often poorly supported, and in more than one study herbaceous bamboos form a clade within the woody bamboos. In this paper, the Bamboo Phylogeny Group presents the most complete phylogeny estimation to date of bamboo tribes and subtribes using 6.7 kb of coding and noncoding sequence data and 37 microstructural characters from the chloroplast genome. Quality of data is assessed, as is the possibility of long branch attraction, the degree of character conflict at key nodes in the tree, and the legitimacy of three alternative hypotheses of relationship. Four major plastid lineages are recognized: temperate woody, paleotropical woody, neotropical woody, and herbaceous bamboos. Woody bamboos are resolved as paraphyletic with respect to Olyreae but SH tests cannot reject monophyly of woody species (Arundinarieae + Bambuseae). Published by Elsevier Inc.
