Essential Roles of Organic Nitrogen Transporters in Whole Plant Physiology

在未来几十年，植物研究必须应对全球对粮食和能源资源日益增长的需求，重点是开发可持续的实践来满足这些需求。一个主要目标是减少农业中合成氮肥的使用，因为这些氮化学品会造成严重的环境污染。该研究项目的重点是植物对氮的吸收和分配，特别是以氨基酸的形式，以了解这些过程如何影响植物生长和生物量产量。植物氨基酸运输的关键成分已经确定，它将确定是否运输过程中的修改可以促进植物适应低氮土壤。此外，通过使用遗传、分子、生物化学和生理学方法，预计将获得对养分分配和氮运输效率的机制的重要见解，这可能导致在不密集施氮的情况下改善植物生长、种子质量和产量。在学术层面，拟议的研究将通过促进学生在植物生物学方面的培训，将研究与科学教育结合起来。Wit预计，该项目的成果将为进一步研究植物运输过程和相互关联的代谢网络提供基础，其长期目标是制定战略，以确保植物生产力用于粮食和生物燃料生产，同时仍然保护环境。

Over the coming decades, plant research must respond to ever-increasing global demands for food and energy resources with a focus on developing sustainable practices to address these needs. One major aim is the reduction of synthetic nitrogen fertilizer usage in agriculture since these nitrogen chemicals cause serious pollution of the environment. the focus of this research project is on nitrogen uptake and partitioning within the plant, specifically in the form of amino acids, in order to understand how these processes affect plant growth and biomass yields. Key components in plant amino acid transport have already been identified and it will be determined whether modifications in transport processes can promote the acclimation of plants to low nitrogen soils. Additionally, by using genetic, molecular, biochemical, and physiological approaches it is anticipated that important insights into the mechanisms of nutrient partitioning and nitrogen transport efficiency will be gained that might lead to improvements in plant growth, seed quality and yields without intensive nitrogen fertilization. At the academic level, the proposed research will integrate research with science education by promoting student training in plant biology. Wit is anticipated that the outcomes of this project will provide a basis for further studies on plant transport processes and interrelated metabolic networks with long-term goals of developing strategies to secure plant productivity for food and biofuel production while still protecting the environment.
