Purification and partial characterization of haloperoxidase from fresh water algae Cladophora glomerata

Various historical eras in the distant as well as the recent past of amphibian embryology are briefly reviewed. The concepts which emerged from the early years matured, then were laid to rest for several decades. A resurgence, driven by key discoveries with peptide growth factors, and fueled by modern molecular biology methods, is underway. The future for several amphibian research projects should be promising since interest in basic concepts remains strong, and application of frontier methodologies is yielding novel findings.
