The affected genes
most likely operate in the same signalling pathway as PaNox1 and PaMpk1.
Interestingly, in P. anserina, this pathway controls the elaboration of fruiting bodies
(Jamet-Vierny et al. 2007). There appears thus to be a connection between encountering
a contestant and triggering of sexual reproduction, a fact well evidenced for
many fungi, which often fruit when in contact with a challenger
