The work described will provide a generic resource for the amalgamation of data on the genetic control of target traits in grass, wheat, barley, rice and other monocots, i.e. information obtained from one species will be directly transferable to the other species. This information will be used by grass, wheat and barley breeders etc. for the development of superior plant varieties. The work is aimed at all traits and not merely a single trait. However, initial work will concentrate on the amalgamation and transfer of genetic information between species on key sustainability and climate change breeding priorities outlined by the Crop Science Review and Defra as well as production traits. These include the traits of nitrogen use efficiency (leading to low fertiliser input), tolerance to abiotic stress and root architecture (leading to prevention of water run off and thus prevention of pollution to water courses and tolerance to drought) for which genes have been identified on Lolium/Festuca chromosomes. The work will make explicit use of the rice genome which has been substantially sequenced and the fact that gene order in the monocot species has to a large extent been maintained during evolution. Research will also be undertaken to improve the efficiency of breeding strategies in grass, wheat, barley and other monocots. In addition the work undertaken will facilitate the identification of genes controlling target traits. This knowledge will be employed and exploited in breeding programmes via conventional means.

所述工作将提供一个通用资源，用于合并关于草、小麦、大麦、水稻和其他单子叶植物目标性状遗传控制的数据，即从一个物种获得的信息将直接转移到另一个物种。这些信息将被草、小麦和大麦育种者等用于开发上级植物品种。这项工作是针对所有的特点，而不仅仅是一个单一的特点。然而，初步工作将集中在作物科学评论和Defra概述的关键可持续性和气候变化育种优先事项以及生产性状的物种之间的遗传信息的合并和转移。这些包括氮利用效率（导致低肥料投入），对非生物胁迫的耐受性和根结构（导致防止水流失，从而防止对水道的污染和对干旱的耐受性）的性状，已经在Lolium/Festuca染色体上鉴定了这些基因。这项工作将明确利用已经大量测序的水稻基因组，以及单子叶植物物种的基因顺序在很大程度上在进化过程中得到维持的事实。还将进行研究，以提高草、小麦、大麦和其他单子叶植物育种战略的效率。此外，所开展的工作将有助于确定控制目标性状的基因。这些知识将通过常规手段在育种计划中使用和利用。
