Homothallism in Sclerotinia minor

Mycological Research, 2006
Sclerotinia species are sexually reproducing ascomycetes. In the past S. minor and S. sclerotiorum, have been assumed to be homothallic because of the self-fertility of colonies derived from single ascospores. S. trifoliorum has previously been shown to be bipolar heterothallic due to the presence of four self-fertile and four self-sterile ascospores ...

Identification of major proteins in sclerotia of Sclerotinia minor and Sclerotinia trifoliorum

Experimental Mycology, 1982
Abstract A major protein was isolated from sclerotia of Sclerotinia sclerotiorum, Sclerotinia trifoliorum , and Sclerotinia minor which comprised ca. 38, 27, and 31% of the total cellular protein, respectively. These proteins were not detected in vegetative cells. The three proteins were similar but not identical.

First Report of Sclerotinia minor on Lettuce in Serbia

Plant Disease, 2022
Lettuce (Lactuca sativa L.) is the world's most popular leafy salad vegetable. One of the major challenges facing lettuce producers are fungal diseases that could, under favorable conditions, devastate the harvest (Raid, 2004). During February 2021, poor growth, plant stunning and blanching of leaves of lettuce plants, cultivated in unheated plastic ...

Transmissible hypovirulence inSclerotinia minor

Canadian Journal of Plant Pathology, 1996
Thirty isolates of Sclerotinia minor were collected from a 4 ha commercial lettuce crop at Holland Marsh, Ontario, and examined for the presence of transmissible hypovirulence. Three slow-growing isolates with atypical colony morphology were less virulent (P = 0.05) on detached lettuce leaves than other isolates and were considered hypovirulent.

β-carotene production and sclerotial differentiation in Sclerotinia minor

Mycological Research, 2003
Sclerotinia minor accumulates beta-carotene at levels dependent upon oxidative growth conditions and differentiation. Beta-carotene accumulation is 2.5-fold higher in differentiated mycelia at high than at low oxidative stress, and approx. 3-fold higher in differentiated than in undifferentiated mycelia.

Production of cellulase and polygalacturonase by sclerotinia minor

Mycopathologia et Mycologia Applicata, 1974
The ability ofS. leroticia micor Jagger to synthesize polygalacturonase and cellulase was studiedin vitro on media containing various carbon sources and was related to fungal growth ability under cultural conditions. Enzymic activityin vivo was studied in inoculated lettuce leaves during disease process.
