^aExperiments were performed as described in Table 1 and Table 2.

^b+, Swarm diameters were 80 to 100% of that of the wild-type cells; −, swarm diameters were less than 80% of that of the wild-type cells.

^c+, Produced normal-looking fruiting bodies; −, failed to produce normal-looking fruiting bodies; +/−, produced normal-looking fruiting bodies but aggregation was delayed.

^d+, Sporulation was 50 to 100% of that of the wild-type cells; −, sporulation was less than 50% of that of the wild-type cells.

^ed, Insertion downstream of the indicated nla gene.
