项目摘要

Extreme and variable climate conditions are expected to become more frequent worldwide with projected climate change. European agriculture is facing the crucial challenge of adapting crop productivity to climate change and will need the development of crops with increased resilience to abiotic stress factors triggered by climate change. Crop yield stability is dependent on the response of key developmental and growth processes to stress conditions. Delayed or accelerated flowering time, alteration of root architecture and growth, and disruption of pod-shattering are common responses displayed by crops exposed to high temperature or drought conditions associated to climate change. SYBRACLIM will evaluate the impact of these environmental factors on developmental and physiological processes directly influencing the yield of oilseed rape, Europe's premium oilseed crop. We will also shed light on the genetic and molecular bases of the tolerance of different rapeseed varieties to increasing temperature and drought stress. The SYBRACLIM consortium is multidisciplinary and includes both commercial breeding companies and leading research groups with high complementarities that cover the fields of genetics, genomics, physiology, breeding and agronomy in Brassica crops along with modeling of crop performance under climate change. Rapeseed is one of the world's most important sources of high-quality vegetable oils for human nutrition and biofuels, and particularly in Europe is also a major contributor to vegetable protein diets for ruminant livestock. SYBRACLIM will implement a multidisciplinary and innovative approach to characterize the phenotypic changes related to flowering time, root development and pod shattering in response to increased temperature and drought, and to analyse the productivity (yield, oil and protein content) in rapeseed varieties. We will also use genomics-assisted selection of stress-tolerance traits in controlled environments and field trials. The relationship between performance and variability of the studied developmental processes will allow us to identify new genetic traits associated with adaptation and use them to design stress tolerant rapeseed crops by complementary plant breeding and biotechnology strategies. Finally, we will integrate all these environmental, phenotypic and productivity data in models that will assess the performance of rapeseed varieties across different climate conditions. These models will be applied to simulate expected performance of rapeseed traits under projected climate change scenarios. Because breeders need decades to develop new varieties, this approach will enable anticipatory breeding for early development of germplasm carrying the necessary genetic variation to cope with climatic changes. SYBRACLIM will provide tools to allow the farmers to design better strategies for adapting cropping systems to climate change, contributing to secure yield of Brassica crops in Europe.

由于预计气候变化，预计极端和可变的气候条件将在全球范围内变得更加频繁。欧洲农业面临着使农作物生产力适应气候变化的关键挑战，并且需要提高农作物的发展，并增加对气候变化触发的非生物压力因素的韧性。作物产量稳定性取决于关键发育和生长过程对压力条件的响应。延迟或加速的开花时间，根结构和生长的改变以及豆荚破碎的破坏是暴露于与气候变化相关的高温或干旱条件的农作物表现出的常见反应。 Sybraclim将评估这些环境因素对发育和生理过程的影响，直接影响欧洲高级油料种子的油料种子强奸产量。我们还将阐明不同菜籽变种对升高和干旱应激的耐受性的遗传和分子碱基。 Sybraclim联盟是多学科的，包括商业育种公司和领先的研究小组，具有高互补性的研究小组，涵盖了胸前植物中遗传学，基因组学，生理学，繁殖和农艺领域，以及在气候变化下作物性能的建模。 Rapeseed是世界上最重要的高质量植物油和生物燃料的来源之一，尤其是在欧洲，也是反刍动物牲畜蔬菜蛋白质饮食的主要贡献者。 Sybraclim将实施一种多学科和创新的方法，以表征与开花时间，根发育和豆荚崩溃相关的表型变化，以响应温度和干旱的升高，并分析泥炭酱品种中的生产力（产量，石油和蛋白质含量）。我们还将在受控的环境和现场试验中使用基因组学辅助耐应力性状的选择。研究过程的性能与可变性之间的关系将使我们能够通过互补的植物育种和生物技术策略来确定与适应性相关的新遗传特征，并利用它们来设计耐受性的菜籽作物。最后，我们将在模型中整合所有这些环境，表型和生产力数据，这些数据将评估在不同气候条件下的菜籽品种的性能。这些模型将用于模拟预计气候变化方案下的菜籽性状的预期性能。由于育种者需要数十年来开发新品种，因此这种方法将使预期的繁殖用于早期发育，从而携带必要的遗传变异以应对气候变化。 Sybraclim将提供工具，使农民能够设计更好的策略，以适应种植系统的气候变化，从而有助于确保欧洲甘蓝植物的产量。
