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不能被夸大，因为它们是我们的主要食品，纤维和其他工业原材料的主要来源。但是，我们产生足够的粮食，动物饲料和能源的能力受到人群的扩张，土地利用竞争，快速生物多样性损失以及预测全球气候变化的能力。对于提高农作物产量，克服杂交障碍以及选择和固定质量特征的目的，高等植物的性繁殖过程尤其重要。在我们开发工具以操纵植物繁殖以使我们有利的工具之前，我们必须更深入地了解鼠尾草植物中的基本机制和双重施肥机制。该项目将对植物性生殖的分子进化提供首个综合观点，并将为开花植物的双重肥料提供洞察力。此外，基因表达数据和产生的网络将在理解生物途径和基因功能预测的进化中具有价值，而不是该项目重点的重点。同时，作物物种的工作将确定对农业产业有用的基因，以实现植物繁殖，克服杂交障碍并通过改善杂交种子生产来促进更好的繁殖方案的精确控制。
