Relevance of FFR1 for sexual development. a Strains were crossed under standard conditions and showed normal sexual development. b If ffr1 is lacking in both mating partners, fruiting body formation is delayed and fruiting bodies of this cross are not yet mature after 18 days. After 25 days, ascospore discharge commences as in the wildtype in the ∆ffr1 crosses. Microscopic pictures show 400x magnification
