The oilseed species Thlaspi arvense (pennycress)—a weed that was only recently removed from the wild—has the potential to provide new sources of food and bioproducts when grown as a winter cover crop. Domestication of wild species has historically taken hundreds to thousands of years, but by making use of large-scale high-throughput comparative gene and phenotype analyses, along with recently developed technological tools, it has been possible to greatly accelerate this process. By taking advantage of extensive gene and phenotype knowledge in the related plant Arabidopsis, mutations for early maturity, reduced pod shatter, reduced seed glucosinolates and improved fatty acid composition were identified. Progress has been made to rapidly stack these traits in order to domesticate the plant, allowing it to fit within current crop cycles and to have improved seed harvestability and nutritional content. Pennycress, domesticated as a winter cover crop, may provide new sources of food, animal feed and bioproducts—and solutions to food security.

油籽物种Thlaspi arvense (pennycress) - 一种最近才从野外移除的杂草 - 当作为冬季覆盖作物种植时，有可能提供新的食物和生物产品来源。从历史上看，野生物种的驯化需要数百到数千年的时间，但通过利用大规模高通量比较基因和表型分析，以及最近开发的技术工具，可以大大加快这一进程。通过利用相关植物拟南芥的广泛基因和表型知识，鉴定出早期成熟突变、减少豆荚破碎、减少种子硫代葡萄糖苷和改善脂肪酸组成。为了驯化植物，在快速叠加这些性状方面取得了进展，使其适应当前的作物周期，并提高了种子的可收获性和营养成分。Pennycress 作为冬季覆盖作物被驯化，可能会提供新的食物来源、动物饲料和生物产品，以及解决粮食安全问题。
