Inhibition of sclerotium formation of Sclerotium rolfsii by compounds related to phenylthiourea
Transactions of the British Mycological Society, 1984The addition of nonpolar groups to thiourea enhanced the ability of compounds to inhibit growth and sclerotium formation of Sclerotium rolfsii. At comparable concentrations, oxygen analogues (urea derivatives) did not inhibit growth or sclerotium formation.

De Novo RNA Sequencing and Transcriptome Analysis of Sclerotium rolfsii Gene Expression during Sclerotium Development [PDF]
Genes, 2023 Sclerotium rolfsii is a destructive soil-borne fungal pathogen that causes stem rot in cultivated plants. However, little is known about the genetic basis of sclerotium development.

Sclerotium formation in an Aspergillus flavus wound infection
Mycopathologia, 1988A patient studied at autopsy was found to have a post-operative wound infection with Aspergillus flavus in which there was the formation of fungal structures resembling sclerotia. The ability of Aspergillus to form sclerotia in tissue appears to be rare and is related to the strain of Aspergillus flavus.

Formation and regeneration of protoplasts of Sclerotium glucanicum
Applied Microbiology and Biotechnology, 1989Protoplast yields from Sclerotium glucanicum using Novozym 234 as the lytic enzyme were affected by the osmotic stabilizers selected, the incubation conditions used for wall degradation, and culture age. Scanning electron microscopic observations revealed that protoplast release from all hyphal regions gradually followed random wall attack, and nuclear

Sterile medium staled by the growth of Sclerotinia sclerotiorum (Lib.) de Bary and Sclerotium rolfsii Sacc. enhanced sclerotium production when applied to test colonies, the active components being acidic and heat stable. In S. sclerotiorum, sclerotium production appeared to be associated with secretion of organic acids, and two unidentified acids with

Cultural Conditions Promoting Sclerotium Formation in Stilbothamnium Togoense
Mycologia, 1990ABSTRACf Stilbothamniumtogoense produced gram quantities ofsclerotia on autoclaved oat seeds and oatmeal. Stipitate sclerotia (2-6 mm diam) developed on oat seeds while sessile sclerotia (1-20 mm diam; ave. = 10 mm) or poorly defined, flat, stromata-like tissues were produced on oatmeal.

Behavior of phosphatase isoforms during sclerotium formation in Physarum polycephalum
Phytochemistry, 2002The behavior of phosphatase isoforms under dark-starvation from plasmodium of Physarum polycephalum were investigated to determine their possible roles in sclerotium formation. Two and a half days after dark-starvation, approximately 95% of plasmodia plates formed sclerotia. Specific phosphatase activity increased markedly up to ca. two-fold within the

Sclerotium formation in Sclerotium rolfsii was completely inhibited by 2-mercaptoethanol at a concentration of 2–4 mM without any adverse effect on mycelial growth. Concentrations lower than 2 mM had no effect on mycelial growth and sclerotium formation, whereas both were inhibited at concentrations higher than 4 mM.

Inhibition of sclerotium formation by Sclerotinia sclerotiorum with fluorophenylalanine
Transactions of the British Mycological Society, 1984Addition of fluorophenylalanine to liquid glucose-sodium nitrate medium affected growth and sclerotium formation of Sclerotinia sclerotiorum . One isolate failed to complete the maturation step in sclerotium formation and has maintained this feature after repeated subculture.

Formation, separation and characterization of three β-1,3-glucanases from Sclerotium glucanicum
Biochimica et Biophysica Acta (BBA) - General Subjects, 1992The appearance of beta-1,3-glucanases in supernatants of Sclerotium glucanicum cultures was followed by SDS-PAGE and shown to be dependent on cultivation time. Three beta-1,3-glucanases were isolated and purified. Glucanase I and III appeared homogeneous on SDS-PAGE with molecular masses of 85 and 33.5 kDa, respectively.
