Brachypodium distachyon (L.) Beauv. is a temperate wild grass species; its morphological and genomic characteristics make it a model system when compared to many other grass species. It has a small genome, short growth cycle, self-fertility, many diploid accessions, and simple growth requirements. In addition, it is phylogenetically close to economically important crops, like wheat and barley, and several potential biofuel grasses. It exhibits agricultural traits similar to those of these target crops. For cereal genomes, it is a better model than Arabidopsis thaliana and Oryza sativa (rice), the former used as a model for all flowering plants and the latter hitherto used as model for genomes of all temperate grass species including major cereals like barley and wheat. Increasing interest in this species has resulted in the development of a series of genomics resources, including nuclear sequences and BAC/EST libraries, together with the collection and characterization of other genetic resources. It is expected that the use of this model will allow rapid advances in generation of genomics information for the improvement of all temperate crops, particularly the cereals.
二穗短柄草是一种温带野生禾本科植物；与许多其他禾本科植物相比，其形态和基因组特征使其成为一个模式系统。它具有基因组小、生长周期短、自交可育、许多二倍体种质以及简单的生长需求。此外，它在系统发育上与经济上重要的作物，如小麦和大麦，以及几种潜在的生物燃料禾本科植物相近。它表现出与这些目标作物相似的农艺性状。对于谷类基因组而言，它比拟南芥和水稻是更好的模式植物，前者被用作所有开花植物的模式，后者迄今被用作包括大麦和小麦等主要谷类在内的所有温带禾本科植物基因组的模式。对该物种兴趣的增加导致了一系列基因组学资源的开发，包括核序列和BAC/EST文库，以及其他遗传资源的收集和表征。预计使用这个模式将使在生成用于改良所有温带作物，特别是谷类作物的基因组学信息方面取得快速进展。
