Differential synthesis of polypeptides during morphogenesis of Mucor.


The extent of differential gene expression during morphogenesis of Mucor racemosus was investigated by two-dimensional polyacrylamide gel electrophoresis of neutral and acidic polypeptides. Cellular proteins were labeled with [35S]methionine in cells growing in either the yeast or hyphal form, or in yeast cells undergoing the transition of hyphae. The results showed that of the 400 to 500 polypeptides resolved by electrophoresis, relatively few were specific to one or the other morphological form. The major change in the patterns of proteins synthesized during morphogenesis was a change in rates of synthesis of individual polypeptides. Experiments in which morphogenesis was affected under aerobic or anaerobic conditions showed that the majority of changes in the protein patterns were associated with morphogenesis and were not a specific response to O2.
