Fig. 2. Terminal morphology and spore characteristics of a random integrant and an
Ax2/gskA clone developing on a bacterial lawn. (A) A random integrant
control is shown at same magnification as B, an Ax2/gskA fruiting body.
The beads on the stalk of the random integrant fruiting body are water
droplets. Scale bar: 100 µm. (C) The spore head of an Ax2/gskA clone
was squashed under a cover slip. (D) The temperature sensitivity of spores,
derived from fruiting bodies that were generated on KK2-agar, was determined
as described in the Materials and methods. The percentage of surviving spores,
relative to the total number of germinating untreated spores, was determined,
and means and standard deviations are shown.
