The economic importance of seed plants cannot be overstated, as they are our main sources of food, fibre and other industrial raw materials. However, our capacity to generate sufficient food, animal feed and energy is increasingly compromised by human population expansion, competition for land use, rapid biodiversity loss and predicted global climate change. The process of sexual reproduction in higher plants is of particular importance for the aim of increasing crop yields, overcoming hybridization barriers and selecting and fixing quality traits. Before we can develop tools to manipulate plant reproduction in our favour we must achieve a deeper understanding of the basic mechanisms underlying gamete development and double fertilization mechanisms in angiosperms.The project will deliver the first comprehensive view of the molecular evolution of plant sexual reproduction and will provide insights into the origins of double fertilization in flowering plants. In addition, gene expression data and the networks generated will be valuable in understanding the evolution of biological pathways and gene function prediction beyond the focus on reproduction in this project. In parallel, the work on crop species will identify genes useful to the agricultural industry to enable precision control of plant reproduction, to overcome hybridization barriers and to promote better breeding schemes by improving hybrid seed production.

种子植物的经济重要性怎么强调都不为过，因为它们是我们食物、纤维和其他工业原材料的主要来源。然而，我们生产足够食物、动物饲料和能源的能力日益受到人口扩张、土地使用竞争、生物多样性迅速丧失和预测的全球气候变化的影响。高等植物的有性繁殖过程对于提高作物产量、克服杂交障碍以及选择和固定品质性状的目的特别重要。在我们开发出有利于我们的植物繁殖工具之前，我们必须更深入地了解被子植物配子发育和双受精机制的基本机制。该项目将首次全面介绍植物有性繁殖的分子进化，并将提供对开花植物双重受精起源的见解。此外，基因表达数据和生成的网络对于理解生物途径的进化和基因功能预测（除了本项目中的繁殖重点）非常有价值。与此同时，作物物种方面的工作将鉴定对农业有用的基因，从而能够精确控制植物繁殖，克服杂交障碍，并通过提高杂交种子产量来促进更好的育种计划。
