Conference: Phosphoinositide Sources of Second Messengers inPlant Growth and Development on April 14-16, 1988 in West Lafayette, Indiana

请支持定于1988年春季举行的一次研究会议，主题是磷酸肌苷作为植物生长和发育中的第二信使的来源。第二信使领域是目前植物生物学研究的一个快速发展的领域。对于涉及多磷酸肌苷的研究尤其如此，在过去十年中，多磷酸肌苷作为动物细胞中主要的第二信使系统的作用已经出现。我们的目标是将植物第二信使领域的专家与专注于肌醇代谢的专家聚集在一起，批判性地讨论植物第二信使的概念，以及肌醇磷酸盐与蛋白激酶和钙一起在激素反应中发挥这种作用的可能性。虽然多磷酸肌苷已被清楚地证明存在于植物中，并在某些发育条件下受到调节，但这些物质在植物中的第二种信使作用仍有待证实，这一领域当然非常需要进行严格的评估。本次会议旨在促进与会者之间的互动，以期出现新的范式，以理解植物中第二信使信号的机制，以及第二信使在植物生长发育中的作用。

Support is requested for a research conference to be held in the spring of 1988 on the subject of phosphoinositides as sources of second messengers in plant growth and development. The area of second messengers currently is one of the rapid growth areas in plant biology. This is especially so for research involving the polyphosphoinositides where a role as a major second messenger system in animal cells has emerged during the last decade. Our goal is to bring a select group of experts in the area of plant second messengers together with those whose work has focused on inositol metabolism to discuss critically the second messenger concept in plants and the possibility that inositol phosphates together with protein kinases and calcium fulfill such a role in hormone responses. While polyphosphoinositides have quite clearly been shown to occur in plants and to be modulated under certain developmental conditions, a second messenger role remains to be proven for these substances in plants, and the field is certainly very much in need of critical evaluation. This conference will be designed to foster interaction among participants with a view toward the emergence of new paradigms for the understanding of the mechanisms of second messenger signalling in plants, and the role of second messengers in plant growth and development.
