This project aims to develop subterranean clover with elevated condensed tannins in leaves. This important pasture legume is currently a bloat risk for cattle and sheep due to low condensed tannins and high soluble proteins. Bloat is a health issue that costs the Australian and New Zealand livestock industries over $200 million per annum. Condensed tannins can reduce bloat, decrease methane production and improve efficiency of production. A novel approach using CRISPR and other innovative molecular techniques will generate breeding lines high in condensed tannins and deliver knowledge applicable to other pasture legumes. Expected outcomes for livestock producers include improved animal welfare, reduced carbon emissions and enhanced profits.

该项目旨在开发叶子中浓缩单宁含量较高的地下三叶草。由于低浓缩单宁和高可溶性蛋白质，这种重要的牧草豆类目前对牛和羊来说存在膨胀风险。臃肿是一个健康问题，每年给澳大利亚和新西兰畜牧业造成超过 2 亿澳元的损失。缩合单宁可以减少膨胀，减少甲烷产生，提高生产效率。使用 CRISPR 和其他创新分子技术的新方法将产生富含浓缩单宁的育种品系，并提供适用于其他牧草豆类的知识。畜牧生产者的预期成果包括改善动物福利、减少碳排放和提高利润。
