A pathogenesis-related (PR) protein from Theobroma cacao (TcPR-10) was identified from a cacao-Moniliophthora perniciosa interaction cDNA library. Nucleotide and amino acid sequences showed homology with other PR-10 proteins having P loop motif and Betv1 domain. Recombinant TcPR-10 showed in vitro and in vivo ribonuclease activity, and antifungal activity against the basidiomycete cacao pathoge...
The basidiomycete fungus Crinipellis perniciosa (Stahel) Singer is the causal agent of Witches' Broom Disease of Cacao (Theobromacacao L.) which is the main factor limiting cacao production in the Americas. Pod losses of up to 90% are experienced in affected areas as evidenced by the 50% drop in production in Bahia province, Brazil following the arrival of the C. perniciosa in the area in 1989....
We report here the first analysis of chitinase regulation in Moniliophthora perniciosa, the causal agent of the witches' broom disease of cacao. A multivariate statistical approach was employed to evaluate the effect of several variables, including carbon and nitrogen sources and cultivation time, on M. perniciosa non-secreted (detected in mycelium, i.e. in symplasm and cell wall) and secreted ...
The hemibiotrophic basidiomycete Moniliophthora perniciosa causes witches' broom disease of Theobroma cacao. Analysis of the M. perniciosa draft genome led to the identification of three putative genes encoding necrosis and ethylene-inducing proteins (MpNEPs), which are apparently located on the same chromosome. MpNEP1 and 2 have highly similar sequences and are able to induce necrosis and ethy...
Moniliophthora perniciosa (Stahel) Aime and Phillips-Mora is a hemibiotrophic basidiomycete (Agaricales, Tricholomataceae) that causes witches' broom disease in cocoa (Theobroma cacao L.). This pathogen carries a stable integrated invertron-type linear plasmid in its mitochondrial genome that encodes viral-like DNA and RNA polymerases related to fungal senescence and longevity. After culturing ...
An isolate of Trichoderma harzianum Rifai from an infected cacao pod produces and secretes nonanoic (pelargonic) acid into a liquid culture medium. Nonanoic acid (NA) was very inhibitory to spore germination and mycelial growth of two cacao pathogens, Crinipellis perniciosa Stahel and Moniliophthora roreri Cif. H.C. Evans. It was highly active causing 75% inhibition of spore germination in an i...
Moniliophthora perniciosa is the causative agent of witches' broom disease, which devastates cacao cultures in South America. This pathogenic fungus infects meristematic tissues and derives nutrients from the plant apoplast during an unusually long-lasting biotrophic stage. To survive, the fungus produces proteins to suppress the plant immune response. Proteins of the PR-1 (pathogenesis-related...
بیماری های حباب خشک قارچ خوراکی دکمه ای با عامل lecanicillium fungicola (preuss)و حباب تر قارچ خوراکی دکمه ای با عامل mycogone perniciosa (magnus) ، از مهمترین بیماری ها در کشت و صنعت های آن در ایران و دنیا محسوب می شوند. این بیماری ها خسارت قابل توجهی به کشت های قارچ وارد کرده و قارچ کاران را تحت اثرات منفی خود قرار داده است. قارچ کش پروکلرز منگنز یکی از قدیمی ترین و تنها بازدارنده موجود برای ...
DNA isolation from some fungal organisms is difficult because they have cell walls or capsules that are relatively unsusceptible to lysis. Beginning with a yeast Saccharomyces cerevisiae genomic DNA isolation method, we developed a 30-min DNA isolation protocol for filamentous fungi by combining cell wall digestion with cell disruption by glass beads. High-quality DNA was isolated with good yie...
