Since its beginnings in the latter half of the nineteenth century, the study of the developmental biology of invertebrates has seen a series of dramatic transformations. In the last two decades we have developed the tools necessary for studying the ontogenic process at the molecular level and are now beginning to link together the cytology of the egg and embryo with their biochemical and molecular organization. Collected in this fifteenth volume of the Belle W. Baruch Library in Marine Science are sixteen papers by authors from major universities that reflect both the breadth and unity of the developmental process of invertebrates. The papers range from studies of the cytological basis for the morphogenic process to the molecular organization of the egg. Of particular interest are considerations of the problems of cytoplasmic localization and the molecular basis for cell and tissue specific differentiation.
Sponsored by the Belle W. Baruch Institute for Marine Biology and Coastal Research and the Biology Department at the University of South Carolina, the Society for Developmental Biology and the American Society of Zoologists, this is the fifteenth in a series of ongoing symposia on marine science supported in part by the National Science Foundation. The papers in this volume were first delivered at a symposium held in honor of Ernest Everett Just at the Hobcaw Barony, Georgetown, South Carolina, in April, 1984. Each paper has received critical outside reviews.
Roger H. Sawyer received his B.A. from the University of Maine and his Ph.D. from the University of Massachusetts. Currently a professor in the Department of Biology at the University of South Carolina, his research interests center on mesenchyme/epithelial interactions during the developmental process, particularly the differential expression of keratin genes during skin morphogenesis.
Richard M. Showman received his B.A. from the University of Chicago and his Ph.D. from the University of Washington. He is currently an Assistant Professor of Biology and Marine Science at the University of South Carolina where he is studying the process of endoderm formation in marine invertebrate embryos.
