Effects of cultivation, conditioning and isolate on sclerotium germination in Sclerotium cepivorum
Plant Pathology, 1992Sclerotium germination in various isolates of S. cepivorum was studied following different cultivation and conditioning treatments. A simple and rapid laboratory test was developed to trigger sclerotial germination under unsterile conditions. In most isolates, sclerotia produced under sterile

Sclerotium rot of sugarbeets in India
Mycopathologia et Mycologia Applicata, 1971Sclerotium rot of sugar beets incited byP. rolfsii is described for the first time from India. The disease has been found widely prevalent around Pantnagar. Observations on the susceptibility of crops grown in the affected areas and the relative susceptibility of different sugarbeets varieties are presented.

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.

Studies on sclerotium-forming fungi
Proceedings / Indian Academy of Sciences, 19471. Symptoms on the natural hosts and the modes of infection of S. cepivorum and S. tuliparum are described. While S. cepivorum appears to be able to penetrate the surface of uninjured roots, it does so relatively slowly and uncertainly whereas it freely enters at the stem base.

Carboxymethylcellulase from Sclerotium rolfsii
1988Publisher Summary Carboxymethylcellulases are predominantly endoglucanases able to catalyze the hydrolysis of glycosidic bonds in the soluble, substituted cellulose, carboxymethylcellulose (CMC). These enzymes, formerly called C x , are important components of the cellulase complex that catalyzes the degradation of crystalline cellulose. This chapter

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

Cellobiose dehydrogenase from Sclerotium rolfsii
1988Publisher Summary This chapter describes the assay method and purification procedure of cellobiose dehydrogenase from Sclerotium rolfsii. The chapter also describes the purity, stability, physical, chemical, and enzymatic properties the purified enzyme. The purified enzyme shows one protein band on polyacrylamide gel electrophoresis at pH 2.9 and 8.

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.
