Assessing resistance to Crinipellis perniciosa using cocoa callus
Plant Pathology, 1990Callus cultures from cocoa clones reported to have different susceptibilities to Brazilian isolates of Crinipellis perniciosa , causal fungus of witches' broom disease, including Catongo (susceptible). Scavina‐6, CAB 64 and CAB 67 (resistant) were inoculated with basidiospores of

Characterization of microsatellites in the fungal plant pathogen Crinipellis perniciosa
Molecular Ecology Notes, 2006AbstractMicrosatellite markers of Crinipellis perniciosa, with three and four repeats, were developed from sequence database and evaluated for their usefulness in detecting genetic polymorphism. Thirty‐three primers produced unambiguous amplification products of 28 microsatellite‐containing loci and 14 microsatellite‐like polymorphic loci, with two to ...

Crinipellis perniciosa: A much investigated but little understood fungus
Mycologist, 1996The recent discovery of Crinipellis perniciosa (Stahel) Singer associated with witches' brooms on a new host plant, in a region far removed from its accepted natural range, raises fundamental questions about its origins and biology. In considering the past and present socio-economic importance of the pathogen in South America, it was felt that a semi-

Crinipellis perniciosa (Agaricales)
Kew Bulletin, 1978Crinipellis perniciosa (Stahel) Singer is one of the more serious plant pathogens, being the causal agent of witches' broom disease of cocoa. Distribution is confined to the cocoa areas of lowland tropical South America, with the disease often reaching epidemic levels in Ecuador, Guyana, Surinam, Trinidad and Tobago.

Analysis of molecular diversity in Crinipellis perniciosa with AFLP markers
European Journal of Plant Pathology, 2005Crinipellis perniciosa causes a serious disease of cacao known as witches’ broom (WB). Heritable resistance to witches’ broom has been used in cacao improvement programs. ‘SCA6’ and ‘SCA12’ are highly resistant and are the most commonly used parents in the breeding schemes.

Sensitivity of Crinipellis perniciosa to procyanidins from Theobroma cacao L.
Physiological and Molecular Plant Pathology, 1995Abstract Basidiospores from four geographic isolates of Crinipellis perniciosa (Stahel) Singer, the pathogen causing witches' broom disease in various members of the Sterculiaceae, Solanaceae and Bixaceae, were exposed to different concentrations of partially-purified oligomeric procyanidins (condensed tannins), (-)-epicatechin/(+)-catechin, and ...

Broken Hyphae of the Basidiomycete Crinipellis perniciosa Allow Quantitative Assay of Toxicity
Current Microbiology, 2006Breaking of hyphae derived from growth of the phytopathogenic fungus Crinipellis perniciosa in liquid media yielded cell aggregates that performed as "quasi single cell" in toxicity assays. When treated with the chemical mutagens 4-nitroquinoleine-1-oxide (4NQO), hydrogen peroxide (H2O2), or paraquat (PAQ) as well as with ultraviolet light (UVC ...
