✦ Synopsis
Microscopic measurements of apical growth and primary branch elongation were compared with nuclear movements, septum synthesis and erosion in a growing ]~-mutant of Schizophyllum commune. Apical growth, mitosis, septum formation, and intercalary cell division were similar to wild-type hyphae. Nuclear replication and new cross-wall formation also occurred in either apical cells bounded by eroding septa or in subterminal cells adjoined by eroded septa. An anucleate subterminal unit of the B-mutant hypha was invaded by a migrant nucleus which subsequently replicated and laid down a new septum in this region. Septum erosion occurred as early as 1 h following synthesis. Cellular granules and filaments were implicated in both septum synthesis and erosion.
