The bamboos (family Poaceae: Bambusoideae), which include the true bamboos and rices, are a morphologically and ecologically diverse group of temperate and tropical grasses that comprise approximately 116 genera and 1300 species. The rices, an important cereal crop, have been extensively studied, but the true bamboos (both woody and herbaceous) are much less well known taxonomically, and large gaps in our knowledge of bamboos remain. Evolutionary relationships among the groups of bamboos, and between bamboos and other grasses, have been only superficially explored. With combined expertise in morphological and molecular techniques, Drs. Clark and Wendel of Iowa State University are studying the taxonomic diversity of bamboos on a worldwide basis. The primary goals of their research are: 1. to produce an explicit and robust phylogenetic hypothesis of bamboo evolution using a combined approach to integrate morphological and genomic data with modern cladistic methods, and 2. to generate a classification of the bamboos at the tribal and generic levels that will ally related groups of species into monophyletic groups (all those likely sharing a recent common ancestor). Morphological studies will include new investigations by scanning electron microscopy of leaf and seed surface features. Molecular studies will include analyses of patterns of restriction-enzyme digests of chloroplast DNA. Collaborators from around the world are supplying samples from the numerous genera of bamboos. The research promises the first global perspective on bamboo evolution uniting morphological and genomic data, and will facilitate subsequent taxonomic and biogeographic studies of bamboos and their close relatives.

竹子（禾本科：Bambusoideae）包括真正的竹子和稻子，是形态和生态多样化的温带和热带禾本科植物，包括约 116 属和 1300 种。 水稻是一种重要的谷类作物，已被广泛研究，但真正的竹子（木本和草本）在分类学上却鲜为人知，我们对竹子的了解仍然存在很大差距。 竹子类群之间以及竹子与其他草类之间的进化关系仅得到了肤浅的探索。 凭借形态学和分子技术方面的综合专业知识，博士。 爱荷华州立大学的克拉克和温德尔正在全球范围内研究竹子的分类多样性。 他们研究的主要目标是：1. 使用组合方法将形态学和基因组数据与现代分支方法相结合，产生明确而稳健的竹子进化系统发育假说；2. 在部落和属级水平上对竹子进行分类，将相关的物种群体联合成单系群体（所有这些物种可能共享最近的共同祖先）。 形态学研究将包括通过扫描电子显微镜对叶子和种子表面特征进行的新研究。 分子研究将包括叶绿体 DNA 限制性酶消化模式的分析。 来自世界各地的合作者正在提供来自众多竹属的样本。 该研究首次将形态学和基因组数据结合起来，对竹子进化提供了全球视角，并将促进随后对竹子及其近亲的分类学和生物地理学研究。
