    Abstract:
    The regulatory effect of two oxyderivatives of unsaturated fatty acids (oxylipins), 18-hydroxy-(9Z,12Z)-octadecadienoic acid (18-HODE) and 18-(9Z,12Z,15Z)-octadecatrienoic acid (18-HOTrE), on the sexual and asexual sporulation of wild-type Neurospora crassa strains and wc-1 and wc-1 mutants was studied. In the wild-type strain, 18-HODE, unlike 18-HOTrE, stimulated protoperithecia formation in the dark and in the light. In the same strain, the studied oxylipins influenced conidiagenesis only under illumination. 18-HODE stimulated and 18-HOTrE inhibited the conidia formation. Oxylipins had no effect on protoperithecia formation in photoreceptor complex mutants, which apparently indicated its involvement in signal transmission in N. crassa. The stimulating action of the studied oxylipins on conidiagenesis in wc-1 and the lack of action in wc-2 may indicate alternative signaling pathways of oxylipins in this process.
