5th Annual Penn State Symposium in Plant Physiology; May l7-19, l990, University Park, PA.

本次研讨会提供了一个最新的评估我们的知识的生物合成，代谢和多胺和乙烯的分子生物学。该领域的杰出研究人员将对多胺和乙烯在植物生长、发育和应激反应中的作用进行批判性分析。这些分子在植物衰老、胁迫和发育中的拮抗作用，以及乙烯和多胺途径的可能调控机制将被研究。多胺和乙烯是第五届宾夕法尼亚州立大学植物生理学年度研讨会将讨论的两个重要主题。多胺是一种化合物，被认为是雄性生殖力和花发育的标志。证据还表明，多胺可以延缓衰老。乙烯已被证明在许多生理过程中起着重要的调节作用，包括性别表达、花的形成和促进衰老。本次研讨会的目的是讨论多胺的各种主题和研究这两个不同但重叠的主题的研究人员，并为未来的创新方法提供催化剂。研讨会将为学生和博士后提供一个不同寻常的机会，在小组环境中与该研究领域的领导者会面和互动。出版的论文集将提供这些快速发展领域的最新研究综述，对高校、政府和工业界的学生和科学家具有普遍价值。

This symposium provides an up-to-date assessment of our knowledge of the biosynthesis, metabolism and molecular biology of polyamines and ethylene. Presentations by outstanding researchers in the field will provide a critical analysis of the involvement of polyamines and ethylene in plant growth, development, and responses to stress. The antagonistic roles of these molecules in senescence, plant stress and development will be examined, as well as the possible regulatory mechanisms for the ethylene and polyamine pathways. Polyamines and ethylene are the two important topics that will be discussed during the 5th Annual Penn State Symposium in Plant Physiology. Polyamines are compounds that have been implicated as markers for male fertility and in flower development. Evidence also suggests that polyamines may retard senescence. Ethylene has been shown to play an important regulatory role in many physiological processes including sex expression, flower initiation and the promotion of senescence. The purpose of this symposium is to address a variety of topics on polyamine and researchers working on these two distinct yet overlapping subjects and provide a catalyst for innovative approaches in the future. The symposium will provide students and post doctoral fellows an unusual opportunity to meet and interact in a small group setting with the leaders in this research area. The published proceedings will provide an up-to-date review of research in these rapidly advancing fields which will be of general value to students and scientists in colleges and universities, government, and industry.
