项目摘要

Agriculture is facing the crucial challenge of adapting crop productivity to changes in the climate. More variable weather patterns require the development of crops that are able to perform more robustly under a wider range of environmental conditions. At the same time, climate change also provides new opportunities for increasing the length of the UK vegetable growing season and increasing food security by reducing imports of fresh produce during the winter, but this requires breeding new varieties that are able to produce robustly at different times of year.The BRAVO consortium aims to meet these challenges through close interactions between academia and industry. To achieve this goal, we have brought together world-leading experts in both Arabidopsis and Brassica plant reproduction from research institutes and universities within the UK. As the result of a series of meetings between consortium members and stakeholders from the oilseed rape and vegetable Brassica industries, optimisation of flowering and coordination of developmental transitions in the production of high-quality seeds were identified as important common targets. These transitions that occur during plant reproduction such as to flowering, fertilisation, inflorescence growth, seed production, dispersal, and subsequent seed performance are now known to be managed by environmentally responsive gene networks built on a foundation of common components first described for their ability to control flowering time.The goal of BRAVO is to provide a mechanistic understanding of the role of flowering time gene networks in the control of Brassica reproductive developmental transitions from vegetative growth through to seed production and seed vigour. Because these networks control environmental responsiveness, this knowledge can be exploited to increase robustness in the performance of oilseed and vegetable Brassicas. A key challenge is how to optimise individual traits when the same flowering time gene network has been optimised by evolution over millions of years for multiple functions, each of which is important for crop performance. In this proposal, we will combine genomics and phenomics technologies with approaches in developmental genetics and mathematical modelling to link genotype to phenotype for master regulators of key transitions during Brassica reproductive development. Through exploitation of available genetic resources, we will reveal the architecture of flowering time gene networks in Brassicas and how they have been modified in the past by plant breeders to cause trait variation, life history variation and climate adaptation. This will allow us to develop a predictive framework for designing strategies to vary specific crop characteristics without harming others, and to generate and test novel genetic variation with potential uses in future trait enhancement.In parallel we will establish and exploit resources such as a gene expression atlas and targeted gene disruption which will allow the Brassica research and breeding communities to expand knowledge on important biological processes and use the outputs form BRAVO collectively to improve Brassica crop performance. Long-term improved and sustainable Brassica crop performance can only be achieved through fundamental understanding of biological processes. The composition of the BRAVO consortium allows the combination of excellence in Brassica research with knowledge transfer from the closely related Arabidopsis model species. The project builds on and expands academia-industry interactions through industrial membership on the project's Supervisory Board, industry engagement and practical involvement in case studies, frequent consortium meetings and annual stakeholder events.We believe this project provides a unique opportunity to align industry priorities with excellent fundamental research programmes in order to help secure the future yield of Brassica crops in the UK and worldwide.

农业面临着使农作物生产力适应气候变化的关键挑战。更可变的天气模式需要开发能够在更广泛的环境条件下更强大的农作物。同时，气候变化还提供了新的机会，可以通过减少冬季的新鲜农产品进口来增加英国蔬菜生长季节的长度，并提高粮食安全，但这需要繁殖新品种，这些新品种能够在一年中的不同时期生产强劲生产。为了实现这一目标，我们将英国研究机构和大学的拟南芥和植物植物繁殖的世界领先专家汇集在一起。由于联盟成员和来自油料种子强奸和蔬菜甘蓝行业的利益相关者之间的一系列会议，优化开花和在产生高质量种子中发育过渡的协调被确定为重要的常见目标。现在已知这些过渡在植物繁殖过程中发生的过渡，例如开花，施肥，花序生长，种子生产，分散和随后的种子性能，由环境响应的基因网络构建为基础上，最初描述的是为了控制BRAV的目标的能力，该网络最初是为了控制BRAVS的发展，该目标是通过对bravo的作用来控制的，以控制brave的发展，以控制植物的机械性，以控制植物的机械性，以控制花朵的机械性，以使植物的机械化范围内的播种，从而在植物上进行了机械性的发展。生长到种子生产和种子活力。由于这些网络控制着环境响应能力，因此可以利用这些知识来提高油籽和蔬菜胸肌的性能。一个关键的挑战是，当相同的开花时间网络通过数百万年以来的多个功能的进化优化了相同的开花时间网络时，如何优化单个特征，这对于作物的性能很重要。在此提案中，我们将将基因组学和现象学技术与发育遗传学和数学建模的方法相结合，以将基因型与甘蓝生殖发育过程中关键过渡的主要调节剂联系起来将基因型与表型联系起来。通过剥削可用的遗传资源，我们将揭示胸前开花时间基因网络的结构，以及过去如何通过植物繁殖者对它们进行修饰，从而引起性状变化，生活史变化和气候适应。这将使我们能够开发一个预测框架，以设计策略，以改变特定的作物特征而不损害他人，并在未来的特征增强中产生和测试新型遗传变异，并同时建立和利用基因表达地图集和诸如靶向基因的基因中的基因上的基因群体，以扩大胸前研究和繁殖的知识，从而建立和利用资源，从而扩大了基因的影响，以扩大其范围。表现。长期改善和可持续的胸罩作物性能只能通过对生物过程的基本理解来实现。 Bravo联盟的组成允许胸前研究中卓越的卓越性与来自密切相关的拟南芥模型物种的知识转移。该项目通过该项目的监督委员会，行业参与和实践参与案例研究，频繁的财团会议和年度利益相关者活动来建立和扩展学术界 - 行业的互动。我们相信，该项目为您提供了一个独特的机会，可以使行业优先级与出色的基础研究计划相结合，以帮助确保BrassaScica Crassica Crapsica Crapsica Crapsica crassica croper of Brassica crops in Uk和Worlderverswormes worldive and worldy worly worldiDED。
