DNA and RNA polymerase activity in a Moniliophthora perniciosa mitochondrial plasmid and self-defense against oxidative stress.
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 ...
متن کاملThe mitochondrial genome of the phytopathogenic basidiomycete Moniliophthora perniciosa is 109 kb in size and contains a stable integrated plasmid.
We present here the sequence of the mitochondrial genome of the basidiomycete phytopathogenic hemibiotrophic fungus Moniliophthora perniciosa, causal agent of the Witches' Broom Disease in Theobroma cacao. The DNA is a circular molecule of 109,103 base pairs, with 31.9% GC, and is the largest sequenced so far. This size is due essentially to the presence of numerous non-conserved hypothetical O...
متن کاملPhylogenetic analysis of HSP70 gene of Aspergillus fumigatus reveals conservation intra-species and divergence inter-species
Aspergillus fumigatus is a saprophyte fungus, widely spread in a variety of ecologicalniches and the most prevalent aspergilli responsible for human and animal invasiveaspergillosis. The first step to develop novel and efficient therapies is the identificationand understanding of the key tolerance and virulence factors of pathogens. The mainfocus of the present study is to perform the similarit...
متن کاملLateral gene transfer of family A DNA polymerases between thermophilic viruses, aquificae, and apicomplexa.
Bioinformatics and functional screens identified a group of Family A-type DNA Polymerase (polA) genes encoded by viruses inhabiting circumneutral and alkaline hot springs in Yellowstone National Park and the US Great Basin. The proteins encoded by these viral polA genes (PolAs) shared no significant sequence similarity with any known viral proteins but were remarkably similar to PolAs encoded b...
متن کاملThe hemibiotrophic cacao pathogen Moniliophthora perniciosa depends on a mitochondrial alternative oxidase for biotrophic development
The tropical pathogen Moniliophthora perniciosa causes witches' broom disease in cacao. As a hemibiotrophic fungus, it initially colonizes the living host tissues (biotrophic phase), and later grows over the dead plant (necrotrophic phase). Little is known about the mechanisms that promote these distinct fungal phases or mediate the transition between them. An alternative oxidase gene (Mp-aox) ...
