Liquid chromatography-mass spectroscopy (LC-MS) equipment for plant metabolism and host-pathogen interactions.

液相色谱-质谱（LC-MS）是一种能够分离和精确鉴定多种生物重要分子的技术。LC-MS将补充埃克塞特大学生物科学学院的气相色谱-质谱仪和核磁共振光谱仪，为生物分子提供分析设施。LC-MS将用于支持植物和微生物科学领域的广泛研究项目。需要支持和启用的项目包括以下项目。1.研究植物中维生素C的合成和功能以及新陈代谢的遗传控制。2.植物对真菌和细菌病原体的反应：抗病性中涉及哪些化学信号和防御化学物质。3.病原菌产生毒素。4.藻类代谢：藻类（浮游植物）对海洋中的光合作用和生产力很重要，是吸收大气中二氧化碳的关键。结合新的基因组序列信息对藻类代谢进行研究，将提供关于藻类对气候变化反应的新信息。

Liquid chromatography-mass spectroscopy (LC-MS) is a technique that allows separation and precise identification of a wide range of biologically-important molecules. The LC-MS will supplement gas chromatography-mass spectrometers and nuclear magnetic resonance spectrometers housed in the School of Biosciences at Exeter University, to provide an analytical facility for biomolecules. The LC-MS will be used to support a wide range of research projects in the area of plant and microbial sciences. The projects to be supported and enabled include the following. 1. Investigations of the synthesis and function of vitamin C in plants and of the genetic control of metabolism. 2. The response of plants to fungal and bacterial pathogens: what kinds of chemical signals and defensive chemicals are involved in disease resistance. 3. Toxin production by pathogenic bacteria. 4. Algal metabolism: algae (phytoplankton) are important for photosynthesis and productivity in the oceans and are key in absorbing carbon dioxide from the atmosphere. Studies of algal metabolism in conjunction with new genome sequence information will provide new information on their response to climate change.
