Sequencing and exploitation of the genetic diversity in Vietnamese native rice lines to serve research and breeding programs

我们建议在越南开发一个现代化的水稻育种平台，重点关注农艺性状。大米是越南9000万人口的主食，也是该国的主要出口商品之一。越南正经历着经济产出和人口增长的异常增长，成为全球领先的农业国家。然而，来自气候变化的威胁越来越大，如新出现的病原体、干旱时期和海平面上升。风险最大的地区是红河和湄公河的三角洲，这是越南主要的水稻种植区。快速筛选出对这些条件具有耐受性和适应性的水稻品种将有助于缓解其中一些挑战，并有助于确保越南的粮食安全。英国的基因组分析中心（TGAC）和越南的农业遗传研究所（AGI）发起了一项合作，对数量减少的越南水稻品种进行基因组测序，目的是检测本地品系的遗传变异，并开发可用于加速水稻育种的分子标记。应用基因组学新技术改进作物育种是英国国家农业植物研究所（NIAB）的优先工作之一。拟议的项目继续TGAC和AGI之间发起的伙伴关系，作为与NIAB的合作。我们的目标是扩大试验计划第一期，以完成约600条铁路线的重新排序。我们将通过数据库的开发和生物信息学管道的应用来补充这些数据的生成，以确定等位基因与特定表型的关联。我们希望找到能使水稻育种更有效的标记。现代技术在水稻育种中的应用也将为这些策略如何应用于小麦和大麦等其他植物物种提供一个很好的例子。水稻基因组简单，已经产生了许多基因组学资源，它为评价和评估新的育种策略提供了一个很好的模型，这些策略以后可以应用于更复杂的作物。与越南的合作也将为与具有水稻育种和农学经验的世界领先科学家合作提供机会。

We propose to develop a modern platform for rice breeding in Vietnam focused on traits of agronomic interest. Rice is a staple food for a population of 90 million in Vietnam and it is also one of the main exporter commodities of the country. Vietnam is experiencing an exceptional growth in its economic output and population rising as a global leading agricultural country. There is, however, an increasing threat from climate change such as emerging pathogens, periods of droughts and rising sea levels. The areas under greatest risk are the deltas of the Red and Mekong rivers, which represent the major rice growing regions of Vietnam. The rapid selection of rice varieties that are tolerant and resilient to these conditions will help to mitigate some of these challenges and contribute to ensure food security in Vietnam. The Genome Analysis Centre (TGAC) in the UK and the Agricultural Genetics Institute (AGI) in Vietnam initiated a collaboration to sequence the genome of a reduced number of Vietnamese rice varieties with the purpose to characterise the genetic variations in native lines and develop molecular markers that could be used to accelerate rice breeding. The application of new genomics technologies to improve crop breeding is one of the priorities at the National Institute of Agricultural Botany (NIAB) at UK. The proposed project continues the partnership initiated between TGAC and AGI as a collaboration with NIAB. We aim at expanding the pilot project phase I to complete the re-sequencing of around 600 lines. We will complement the generation of these data with the development of databases and the application of bioinformatics pipelines to identify associations of alleles with specific phenotypes. We expect to characterise markers that will enable more efficient rice breeding. The application of modern technologies to rice breeding will also provide an excellent example of how these strategies could be applied to other plant species such as wheat and barley. Rice has a simple genome for which many genomics resources have been already generated and it offers an excellent model for the evaluation and assessment of new strategies for breeding that could later be applied to more complex crops. This collaboration with Vietnam will also open opportunities to work with world leading scientists with experience in rice breeding and agronomy.
