Hunger and malnutrition are the leading risks to health worldwide. Every year, hunger kills 1.5 million children (World Food Programme, UN). It is critical to find new, sustainable and more efficient methods of increasing crop productivity to ensure food security for Europe (Lisbon Treaty, Horizon 2020) and the World as soon as possible. This programme of work will contribute to finding them. Plant development is crucial for crop yield. Creating more resilient plants will increase fruit and seed production, pollination and ultimately crop yield. This innovative, multidisciplinary project will elucidate the key roles of two corn genes during the plant development in corn, including the creation of novel flowers, plant boundary formation, and how two regulatory mechanisms interact during these events.Previous and current research1,2,3 in our lab demonstrates that the HAWAIIAN SKIRT, an F-box gene in Arabidopsis, plays an important role in microRNA biogenesis and protein degradation; which have an impact in flower and plant development and abiotic stresses.1González-Carranza, Z.H., Peters, J.L., Zhang X., and Roberts, J.A.

饥饿和营养不良是全球健康面临的主要风险。每年有150万儿童死于饥饿（世界粮食计划署，联合国）。必须尽快找到新的、可持续的和更有效的提高作物生产力的方法，以确保欧洲（里斯本条约，地平线2020）和世界的粮食安全。本工作方案将有助于找到这些目标。植物发育对作物产量至关重要。创造更有弹性的植物将增加水果和种子产量，授粉和最终作物产量。本实验室过去和现在的研究表明，拟南芥中的一个F-box基因HAWAIIAN SKIRT在microRNA的生物合成和蛋白质降解中起着重要作用;其对花和植物发育以及非生物胁迫具有影响。1 González-Carranza，Z.H.，彼得斯，J.L.，张旭，和Roberts，J.A.（2014 a）拟南芥HWS通过miR 164改变CUC 1和CUC 2的转录水平来控制花器官数量和大小。提交给Plant Cell，（2014年11月）2 Yu，H.，Murchie E H、冈萨雷斯-卡兰萨H、派克湾一、罗伯茨（2014）水稻直立穗3（ep 3）突变体的光合作用降低与气孔导度降低和保卫细胞发育减弱有关。提交给JExpBot.3González-Carranza，Z.H.，张旭，彼得斯以及罗伯茨。（2009年）。泛素化和miRNA途径在花发育调控中的相互作用。第20届拟南芥研究国际会议，P037，P12。
