Investigation into the roles of Arabidopsis calcium sensors in stress response and development

植物必须不断地监测它们的环境，并通过适当的细胞和生理适应来响应变化。当面临病原体侵袭、干旱或盐分等不利的环境胁迫时，植物会启动特定的、适应性的细胞反应，包括基因表达、酶活性和代谢调节的变化。这些反应是通过复杂的信号系统来调节的，这些信号系统有助于将细胞的机械协调成一种协调的反应，这种反应针对给定的应激反应是适当的和特定的。植物在对几乎所有类型的生物和非生物胁迫做出反应时，利用钙离子作为信号分子和调节器。我的研究重点是了解植物细胞使用钙离子和钙结合蛋白来调节胁迫反应和发育的独特方式。我的实验室在我们的研究项目中使用了各种分子、遗传和生化工具。这项工作将增进我们对植物细胞生物学和逆境生理学的了解。这项研究对学术界、生物技术和农业界都具有重要意义。它为未来旨在提高加拿大作物抗逆性的工程应用奠定了基础。

Plants must continually monitor their environment and respond to changes with appropriate cellular and physiological adaptations. When faced with adverse environmental stress such as pathogen attack, drought, or salinity, plants initiate specific, adaptive cellular responses which include changes in gene expression, enzyme activity, and metabolic adjustments. These responses are regulated through intricate signalling systems that help orchestrate the cell's machinery into a coordinated response that is appropriately timed and specific for the given stress. Plants use calcium ions as signalling molecules and regulators during responses to virtually all types of biotic and abiotic stress. My research focuses on understanding the unique ways in which plants cells use calcium ions and calcium binding proteins to regulate stress response and development. My lab uses a variety of molecular, genetic, and biochemical tools in our research program. This work will advance our knowledge of plant cell biology and stress physiology. This research is important to the academic, biotechnology, and agricultural communites. It provides the foundation for future applications aimed at engineering enhanced stress tolerance in Canadian crops.
