Fundamentals of fungal molecular population genetic analyses.
The last two decades have seen tremendous growth in the development and application of molecular methods in the analyses of fungal species and populations. In this paper, I provide an overview of the molecular techniques and the basic analytical tools used to address various fundamental population and evolutionary genetic questions in fungi. With increasing availability and decreasing cost, DNA...
متن کاملGenetic diversity of Neotyphodium fungal endophytes in three Iranian grass species using AFLP molecular markers
Genetic diversity of fungal endophytes, Neotyphodium species, was studied in grasses Festuca arundinacea, F. pratensis and Lolium perenne using AFLP markers. Fungi were isolated from the host leaf sheaths and Neotyphodium species were selected based on morphological characteristics. To confirm identity of selected fungi belonging to the genus Neotyphodium, polymerase chain reaction was perform...
متن کاملMolecular evolution: Please release me, genetic code
The genetic code is no longer universal, even in non-mitochondrial genomes. Recent studies have implicated the eukaryotic release factor eRF1 in mediating coding changes that are not as inconceivable as once thought. Specific residues in eRF1 proteins can be correlated with specific code changes in a wide variety of taxa.

متن کاملA Genetic Code Alteration Is a Phenotype Diversity Generator in the Human Pathogen Candida albicans
BACKGROUND The discovery of genetic code alterations and expansions in both prokaryotes and eukaryotes abolished the hypothesis of a frozen and universal genetic code and exposed unanticipated flexibility in codon and amino acid assignments. It is now clear that codon identity alterations involve sense and non-sense codons and can occur in organisms with complex genomes and proteomes. However, ...
