0306765CartwrightThe symposium, "Patterning Along an Axis: Insights from Cnidarian Development," will be held at the 7th International Conference on Coelenterate Evolution, July 6-11, 2003, at the University of Kansas in Lawrence Kansas. Funding for this symposium will provide an opportunity for the sharing of information and ideas regarding axial patterning in cnidarians and its implications for metazoan evolution. Previous studies have revealed evidence for similar mechanisms controlling axial patterning in distantly related organisms, suggesting that the regulation of axial patterning is highly conserved across the Metazoa. Most of this information comes from model organisms in the Bilateria. The cnidarians, a probable sister group to bilaterians, require axial patterning mechanisms to specify the various developing axes represented in a typical life cycle; the anterior/posterior axis of the planula larva, the aboral/oral axis in polyp and medusoid forms, and the developing axes of stolons from which polyps bud in colonial forms. The extent to which these axes and axial patterning mechanisms are shared within bilaterians is largely unknown, but many genes have been characterized in cnidarians whose sequence and expression patterns suggest similarities with Bilateria axial patterning genes. The basal phlyogenetic position of the Cnidaria make this an ideal group for providing important clues for understanding how axial patterning mechanisms evolved. This symposium will bring together cnidarian biologists who study different cnidarian species and different aspects of cnidarians axial patterning, including larvae, polyps, medusae and colony-wide patterning. This provides a unique and timely opportunity to develop a greater understanding of how the developmental axes in the cnidarian body plan are regulated to generate the diverse forms found within the Cnidaria, and to assess the degree in which mechanisms of cnidarian development are shared with other metazoans.

0306765Cartwright 研讨会“沿轴图案化：刺胞动物发展的见解”将于 2003 年 7 月 6 日至 11 日在堪萨斯州劳伦斯市的堪萨斯大学举行的第七届腔肠动物进化国际会议上举行。 本次研讨会的资助将为分享有关刺胞动物轴向模式及其对后生动物进化的影响的信息和想法提供机会。先前的研究已经揭示了在远缘相关生物体中控制轴向模式的类似机制的证据，表明轴向模式的调节在后生动物中是高度保守的。 这些信息大部分来自两侧对称动物的模式生物。 刺胞动物可能是两侧对称动物的姐妹类群，它们需要轴向模式机制来指定典型生命周期中所代表的各种发展轴。浮浪幼虫的前/后轴，水螅体和水母形式的口轴/口轴，以及息肉以群体形式发芽的匍匐茎的发育轴。这些轴和轴向模式机制在两侧对称动物中共享的程度在很大程度上尚不清楚，但许多基因已在刺胞动物中得到表征，其序列和表达模式表明与两侧对称对称动物轴向图案基因相似。 刺胞动物的基础系统发育位置使其成为一个理想的类群，为理解轴向模式机制如何进化提供重要线索。本次研讨会将汇集刺胞动物生物学家，他们研究不同的刺胞动物物种和刺胞动物轴向模式的不同方面，包括幼虫、息肉、水母和群体范围的模式。 这提供了一个独特而及时的机会，可以更好地了解刺胞动物身体计划中的发育轴如何调节以产生刺胞动物内发现的多种形式，并评估刺胞动物发育机制与其他后生动物共享的程度。
