Table 1. Sporulation phenotypes of WT versus fmt mutant.

Scoring of different sporulation phenotypes (number of cells) of WT and fmt at 4 and 24 h after initiation of sporulation by resupension. Membrane migration associating with engulfment of the forespore to generate sporangia (a cell in the process of sporulation) was monitored by membrane staining. Polar septa (%) indicates the percentage of polar septa relative to total cells.

Phenotype	No. of cells
	WT 4 h	fmt 4 h	WT 24 h	fmt 24 h
Flat polar septa	177	240	0	89
Engulfing	400	76	0	0
Membrane migration complete	181	186	163	1078
Engulfment complete	89	0	857	76
Not sporulating	228	638	0	0
Total sporangia	847	502	1020	1243
Total cells	1075	1140	1020	1243
Polar septa (%)	12	16	0	7
Engulfing (%)	37	7	0	0
Complete migration (%)	17	16	16	87
Complete engulfment (%)	8	0	84	6
