Sclerotium Rolfsii Sacc. in Perfect Stage Vii. Germination of Basidiospores
In nature Sclerotium Rolfsii attacks the hosts usually at their foot. In a case was observed by the author a Hibiscus plant attacked at about a meter above the ground. By what means the pathogene reached at that height is still unknown. It may be possible that the infection has been caused by basidiospores transported by flow of air. It is therefore interesting to know the relation of germinati...
متن کاملStudies on the basidial Formation by Sclerotium rolfsii Sacc XII. A Discussion on the basidial Stage of Sclerotium Rolfsii Sacc. Isolates and its Identity
In the earlier papers (Series I to XI, 1965) the authors had already reported the success obtained in getting basidial stage of Sclerotium rolfsii Sacc. isolates from potato, Colocasia and groundnut (Arachis hypogea L.) and media as well as conditions under which these stages could be obtained. It is proposed to review these in this paper and discuss in detail the basidial stage of S. rolfsii a...
متن کاملIsolation and fusion of protoplasts from the phytopathogenic fungus sclerotium rolfsii(sacc.)
Sclerotium rolfsii (Sacc.) is a serious plant pathogenic fungus and lacks perfect (basidial) stage in production. Protoplast fusion technology was employed to reconstruct fusants from this fungus. Two strains designated as A and R were used. Maximum protoplast yields of 3.8x10(5)/g mycelia and 2.8x10(5)/g mycelia were formed in strains A and R respectively. Osmotic stabilizer sucrose 1M gave ma...
متن کاملThe crystal structure of the sclerotium rolfsii lectin
Lectins are non-enzymic carbohydrate binding proteins present in plants, bacteria, fungi, and animals, which preferentially bind reversibly to specific carbohydrate structures whether free in solution or on cell surfaces and play important role in cell recognition. Sclerotium rolfsii, a soil borne plant pathogenic fungus capable of forming fruiting bodies referred to as sclerotial bodies, secre...
متن کاملFirst Report of Sclerotium Rot on Cymbidium Orchids Caused by Sclerotium rolfsii in Korea
Sclerotium rot was found on Cymbidium orchids at Seosan-si, Chungcheongnam-do, Korea, in July, 2010. Symptoms occurred on low leaves, which turned yellowish, after which the entire plant wilted. Severely infected plants were blighted and eventually died. White mycelial mats and sclerotia appeared on pseudobulbs. Based on the mycological characteristics and pathogenicity, the causal fungus was i...
