Fertilization Symposium: Fifth International Invertebrate Reproduction Congress, July 23-28, 1989, Nagoya, Japan

这项提议的目的是为参加将于1989年7月23日至28日在日本名古屋举行的第五届国际无脊椎动物繁殖大会的一个专题讨论会的三名发言者提供旅费。本次会议的主讲人将介绍棘皮动物、棘皮类动物和海鞘类动物的最新研究成果，包括卵包膜形成的生物化学、精子-卵子结合的分子基础、卵子活化的受体、离子信号转化为代谢反应的转导以及精子通过卵包膜的酶学。这次大会在无脊椎动物门的繁殖方面是独一无二的，汇集了来自世界各地的研究人员。所提供的机会将导致重要的信息传播和进一步的研究见解，特别是在重要的无脊椎动物模型系统的施肥和一般的发展。

The objective of this proposal is to provide travel costs for three speakers to participate in a symposium on Fertilization to be held as a part of the 5th International Congress of Invertebrate Reproduction in Nagoya, Japan, July 23-28, 1989. The speakers in this session will describe current work on echinoderms, echiuroids and ascidians covering frontier research on biochemistry of egg envelope formation, molecular basis of sperm-egg binding, receptors for egg activation, transduction of ionic signals into metabolic responses and the enzymology of sperm passage through the egg coat. %%% This Congress is unique in looking at reproduction in the invertebrate phyla and brings together researchers from around the world. The opportunity provided will lead to important dissemination of information and to further research insights about fertilization in particular and development in general in important invertebrate model systems.
