Summary

Current Topics in Developmental Biology, Volume 45 surveys the major issues at the forefront of developmental biology. This volume, like others in the serial, is valuable to researchers in the fields of animal and plant development, and to students and other professionals who want an introduction to current topics in cellular and molecular approaches to developmental biology. Chapters on the nervous system, reproductive system, and flowering introduce new models and concepts for understanding these processes.Key Features* Includes development of the nervous and reproductive systems* Covers flowering in plants* Highlights the roles of homeobox-related transcription factors and growth factors in axis and organ development
