The zygote nucleus remains a short time in a resting state, then passes over into the prophase. It migrates to the tip of the probasidium and begins synapsis.

( X 375; after Gaumann, 1922.) extramatrical part in Fig. 363. Their ends become clavate, the two nuclei approach and fuse (Fig. 364, 2 and 3). The zygote nucleus remains a short time in a resting state, then passes over into the prophase. It migrates to the tip of the probasidium and begins synapsis. Meanwhile a parallel branch is formed below the primary probasidium, the dicaryon of the uppermost hyphal cell, the subterminal cell, migrates to the top of the cell and divides conjugately. One-half the daughter nuclei slip into the branch which again swells to a probasidium and pushes aside the primary probasidium. The other half remain in the hyphal cell where the formation of new probasidia is repeated (Fig. 364, 3 to 5), finally resulting in the structure shown in Fig. 364, 1; thus the whole development of probasidia rests in the dicaryon of the subterminal Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Gäumann, Ernst Albert, 1893-1963; Dodge, Carroll William, 1895-.
