Phylogenetic Placement and Morphological Characterization of Sclerotium rolfsii (Teleomorph: Athelia rolfsii) Associated with Blight Disease of Ipomoea batatas in Korea
In this study, we aimed to characterize fungal samples from necrotic lesions on collar regions observed in different sweetpotato growing regions during 2015 and 2016 in Korea. Sclerotia appeared on the root zone soil surface, and white dense mycelia were observed. At the later stages of infection, mother roots quickly rotted, and large areas of the plants were destroyed. The disease occurrence ...
متن کاملSclerotium 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 کاملHost Infection beyond the Traditional Range of Sclerotium (Athelia) rolfsii with Physalis minima
Physalis minima is an herbaceous plant and inhabitant of the porous and organic matter containing soil of bunds in crop fields, wastelands, around the houses, and on the roadsides. S. rolfsii is soil borne and it can infect over 500 plant species of different families. It is of interest to study the pathogenesis of S. rolfsii on P. minima. The S. rolfsii isolated from P. minima (physr1) was cha...
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...
