阐明拟南芥果实模式的关键调控因子有助于将知识转化为作物物种，以解决种子过早传播（荚果破碎）造成的产量损失。在20世纪80年代，植物科学家对一种小型杂草拟南芥（拟南芥）进行了研究，并将其发展成为研究植物生物学的强大模型系统。从那时起，遗传学和基因组学的巨大进步使我们能够获得关于拟南芥生长和发育的特定生物学过程，其基因组序列和许多单个基因功能的令人难以置信的详细知识。这些丰富的信息为转化为作物提供了巨大的潜力，以提高其性能并解决粮食安全等具有全球重要性的问题。在这里，我们描述了如何对种子传播发生在芸苔科成员的遗传机制的基本见解可以用来减少油菜（芸苔）的种子损失。我们证明，利用模式物种的基因功能数据，可以调节油菜的开荚过程，从而显着提高产量。具体来说，我们在b中发现了indehiscentr和ga4基因的多个旁系突变。油菜通过结合突变等位基因克服了遗传冗余。最后，我们提出了一种新的软件，用于分析豆荚破碎数据，适用于任何作物的种子传播是一个严重的问题。这些发现突出了基础研究在指导作物改良策略方面的巨大潜力。
Key messageElucidation of key regulators inArabidopsisfruit patterning has facilitated knowledge-translation into crop species to address yield loss caused by premature seed dispersal (pod shatter).AbstractIn the 1980s, plant scientists descended on a small weedArabidopsis thaliana(thale cress) and developed it into a powerful model system to study plant biology. The massive advances in genetics and genomics since then have allowed us to obtain incredibly detailed knowledge on specific biological processes ofArabidopsisgrowth and development, its genome sequence and the function of many of the individual genes. This wealth of information provides immense potential for translation into crops to improve their performance and address issues of global importance such as food security. Here, we describe how fundamental insight into the genetic mechanism by which seed dispersal occurs in members of the Brassicaceae family can be exploited to reduce seed loss in oilseed rape (Brassica napus). We demonstrate that by exploiting data on gene function in model species, it is possible to adjust the pod-opening process in oilseed rape, thereby significantly increasing yield. Specifically, we identified mutations in multiple paralogues of theINDEHISCENTandGA4genes inB. napusand have overcome genetic redundancy by combining mutant alleles. Finally, we present novel software for the analysis of pod shatter data that is applicable to any crop for which seed dispersal is a serious problem. These findings highlight the tremendous potential of fundamental research in guiding strategies for crop improvement.
