Pleomorphism in Crinipellis perniciosa, causal agent of witches' broom disease of cocoa

Transactions of the British Mycological Society, 1980
Basidiospores of Crinipellis perniciosa (Stahel) Singer germinated rapidly in water and on standard agar media to produce a fine, hyaline, binucleate mycelium 1.5-3 μm diam, with clamp-connexions; the secondary or dikaryotic mycelium. White to cream, fast-growing, regular, cotton-like colonies were formed on agar. The primary mycelium was short-lived

Caracterização bioquimica e molecular de quitinases de Crinipellis perniciosa

2010
La chitine est un homopolymere de [béta] 1-4 N-acetylglucosamine et elle est le principal composant de la paroi cellulaire de diverses espèces de champignons, de l'exosquelette des arthropodes et de la cuticule des nématodes Beaucoup de ces organismes sont responsables de maladies sévères pour les cultures vivrières, et la chitine devient une bonne ...

Anti-fungal effects of cocoa tannin on the witches' broom pathogen Crinipellis perniciosa

Physiological and Molecular Plant Pathology, 1990
Abstract Methanol-extractable material from flush shoot tissue of cocoa (Theobroma cacao) inhibited the germination of basidiospores of the witches' broom pathogen Crinipellis perniciosa. In more dilute extracts, abnormally short, swollen germ-tubes emerged from the basidiospores.

Understanting the Theobroma cacao - Crinipellis perniciosa interaction using ESTs and proteomic analyses [PDF]

, 2004
Using the tert-Butanol RNA extraction protocol, we succeeded, for the first time, in isolating RNA from cocoa organs infected by C. perniciosa. These results have led to new perspectives regarding the understanding, through genomic studies, of the cellular mechanisms of the infection of the cocoa tree by destructive pathogens such as Crinipellis or ...

Análise molecular da interação entre frutos de cacau e Crinipellis perniciosa

2010
Pour identifier et caractériser les gènes associés moléculairement à la résistance à la maladie des balais de sorcière du cacaoyer (MBS), une bibliothèque d'ADNc a été construite en utilisant le Creator Smart cDNA Library Construction Kit de Clontech. #Crinipellis perniciosa# (Cp), l'agent causal de la MBS, a été inoculé dans des cabosses de cacaoyer ...

Development of microsatellite markers for the genetic analysis of Crinipellis perniciosa

2005
La maladie du balai de sorcière, causée par Crinipellis perniciosa (Stahel) Singer, est la plus importante maladie du cacaoyer (Theobroma cacao L.) dans les zones de culture cacaoyère d'Amérique du Sud et des Iles Caraïbes. On sait peu de choses de la biologie génétique de la population pathogène, et ces informations sont très importantes pour les ...

Occurrence, Anatomy, and Morphology of 'Blisters' on Cocoa Seedlings Inoculated with Crinipellis perniciosa

Plant Disease, 1989
The rupturing of blisters resulted in desiccation, necrosis, and brown discoloration of the exposed cells. The exudation was not associated with the disintegration of host tissue and was probably due to the high internal pressure generated by hyperplasia and hypertrophy of infected tissues.

An Inoculation Method for Evaluating Resistance of Cacao toCrinipellis perniciosa

Plant Disease, 1995
Methods are described to collect and store basidiospores of Crinipellis perniciosa and to inoculate seedlings of cacao (Theobroma cacao) for evaluation of resistance to witches'-broom disease. Basidiospores of C. perniciosa collected overnight in a 16% glycerol solution (containing buffer and Tween 20) remained viable but did not germinate until the ...

Estudos funcionais de genes envolvidos na interação Theobroma cacao: Crinipellis perniciosa

2004
O fungo Crinipellis perniciosa (Cp), agente causador da doença conhecida como vassoura-de-bruxa do cacaueiro, tem dizimado as plantações de Theobroma cacau L. (cacau) da região sul da Bahia gerando forte impacto econômico, social e ecológico. A ampliação do conhecimento da biologia do fungo e dos mecanismos da interação patógeno-hospedeiro poderá levar

Research Infection Biology ofCrinipellis perniciosaon Vegetative Flushes of Cacao

Plant Disease, 1991
Infection biology of Crinipellis perniciosa on vegetative flushes of cacao (Theobroma cacao) was studied by fluorescent microscopy. Basidiospores germinated only if they landed on wet tissue or were suspended in water and sprayed onto the plant parts; those landed on dry surfaces were no longer viable.
