Morphogenesis in sclerotium forming fungi part 1 effects of light on sclerotinia sclerotiorum sclerotium delphinii and sclerotium rolfsii



Morphogenesis in sclerotium forming fungi part 1 effects of light on sclerotinia sclerotiorum sclerotium delphinii and sclerotium rolfsii



New Phytologist 78(1): 171-180



Sclerotium production by Sclerotinia sclerotiorum (Lib.) de Bary, Sclerotium rolfsii Sacc. and S. delphinii Welch was enhanced by white light, the most effective wavelengths being in the blue and near-UV regions of the spectrum. Sensitivity of dark-grown cultures to light decreased with age. The effect of light appeared to be through the direct induction of sclerotium initials on undifferentiated hyphae. The relevance of these observations to the general study of sclerotium morphogenesis is discussed.
