Fertility of the homeobox gene mutants.

<p>Repartition of fruiting bodies in homeobox mutants (top). Eight-centimeter M2 plates were inoculated in the center with mat+/mat− heterokaryotic cultures and incubated for seven days. Perithecia are visible as small black dots. Morphology of fruiting bodies in the Δ<i>pah</i> mutants (bottom). Images are from representative fruiting bodies from the plates in the top panel. For Δ<i>pah2</i>, arrows indicate perithecia with neck and arrowheads indicate perithecia without neck. WT, wild type.
