Mechanisms of Development is an international journal whose purpose is to communicate contemporary studies in developmental biology with special emphasis on the characterization of molecular mechanisms underlying development processes in either vertebrates, invertebrates or plants. Areas of particular interest include embryogenesis, pattern formation, cell determination and differentiation, specification of tissue type, targetted disruptions of developmental control genes, the roles of transcription factor in development, regulatory hierarchies of gene expression, cell-cell communication and signal transduction in development, as well as post-transcriptional controls of developmental processes such as regulated splicing and protein modification.Such a focus should provide a unique forum for comparing and contrasting strategies of development among a wide spectrum of organisms. The Editors are strongly committed to establishing the highest standards of quality and scientific merit, and guarantee rapid communication of important contributions.NOTE: A combined MOD subscription and ISDB membership is now available through Elsevier's Customer Service Department. The price for 1999 has been fixed at 125.00 US Dollars (plus VAT for residents of the European Union). Further information: please contact the nearest Regional Sales Office
