While modern agriculture relies heavily on the use of phosphorous fertilizers, most of them are not used by plants and lost in runoff, resulting in a massive environmental damage through contamination of waterways (termed eutrophication). This project takes advantage of an untapped resource - a unique collection of Tibetan wild barley genotypes, to reveal key traits that confer superior phosphorus use efficiency in wild barley and identify appropriate candidate genes and their position on chromosomes for further incorporating these traits into commercial barley cultivars. This will reduce the environmental footprint of modern agricultural practices on terrestrial and aquatic ecosystems without compromising food security.

虽然现代农业在很大程度上依赖于磷肥的使用，但大多数磷肥都没有被植物利用，并在径流中流失，通过污染水道（称为富营养化）造成大规模的环境破坏。本项目利用西藏野生大麦基因型的独特集合这一尚未开发的资源，揭示野生大麦中赋予上级磷利用效率的关键性状，并鉴定合适的候选基因及其在染色体上的位置，以进一步将这些性状整合到商业大麦品种中。这将在不损害粮食安全的情况下减少现代农业做法对陆地和水生生态系统的环境足迹。
