Unboxing the mysteries of the maize orthologs of the HAWAIIAN SKIRT F-box gene from Arabidopsis

饥饿和营养不良是全世界健康面临的主要风险。每年有150万儿童死于饥饿（联合国世界粮食计划署）。必须尽快找到新的、可持续的和更有效的方法来提高作物生产力，以确保欧洲（《里斯本条约》、《地平线2020》）和世界的粮食安全。这项工作方案将有助于找到它们。植物发育对作物产量至关重要。培育更具弹性的植物将增加果实和种子的产量、授粉，并最终提高作物产量。这个创新的多学科项目将阐明两个玉米基因在玉米植物发育中的关键作用，包括新花的产生，植物边界的形成，以及两个调控机制在这些事件中如何相互作用。我们实验室过去和现在的研究表明，拟南芥中的F-box基因HAWAIIAN SKIRT在microRNA的生物发生和蛋白质降解中起重要作用；它们对花和植物的发育和非生物胁迫有影响。[2]张晓明，张晓明，张晓明，张晓明，张晓明（2014）拟南芥HWS通过miR164基因调控花器官数量和大小的研究进展[j]。[2]于洪华，刘志强，李志强，李志强，等。（2014）水稻直立穗3 （ep3）突变体的光合作用与气孔导度降低和保护细胞发育减弱有关。植物生理学报，（11）提交给JExpBot。3González-Carranza，张欣，peter J.

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.
