Abstract

Determinants of Spatial Organization documents the proceedings of the 35th symposium of the Society for Developmental Biology in 1978. The symposium brings together a diverse group of investigators who are engaged in the analysis of mechanisms involved in spatial organization.
The contributions made by researchers at the symposium are organized into three parts. Part I on the cytoplasmic localization of determinants includes studies on fine structure of cytoplasmic specializations of the polar lobe of molluscan embryos; the fine structure of the polar granules of Drosophila eggs; and the polarity of rhizoid formation in Fucus. Part II deals with maternal-effect mutants of developmental processes. It includes studies on temperature sensitive maternal effect mutants in the free-living nematode Caenorhabditis elegans; the nature of the control of gene action during development; and deviations from normal development observed in mutant embryos of Drosophila melanogaster. Part III examines pattern formation in developing systems. It includes studies on intracellular patterning in Tetrahymena; developmental properties of nerve-free hydra; and intercellular interactions and pattern formation in filamentous cyanobacteria.
