Abstract Sexual reproduction is the basic way to form high genetic diversity and it beneficial in evolution speciation of fungi. The global teleomorphic species Ascomycota has not been estimated. This paper estimates number for sexual ascomycetes based on five different estimation approaches, viz. by numbers described fungi, fungus:substrate ratio, ecological distribution, meta-DNA barcoding or...

During 2009–10, the presence of ascomycetous species in soil was studied in Fars province. Isolates were recovered from soil using modified Czapek (Raper et al. 1973), malt extract agar (MEA) and potato dextrose agar (PDA). Teleomorphic characteristics such as morphology of ascocarps, asci, ascospores and anamorphic characteristics such as conidiophores, phialides, conidia and chlamydospores we...

The historical and contemporary population genetic structure of the chickpea Ascochyta blight pathogen, Ascochyta rabiei (teleomorph: Didymella rabiei), was determined in the US Pacific Northwest (PNW) using 17 putative AFLP loci, four genetically characterized, sequence-tagged microsatellite loci (STMS) and the mating type locus (MAT). A single multilocus genotype of A. rabiei (MAT1-1) was det...

Previous phytopathological studies of the fungal pathogen Nectria cinnabarina have been focused on its distribution and host diversity but little is known about spread this defence responses forest trees to an infection inside tissues. Histopathological alterations bark, periderm, phloem woody tissues were investigated in sycamore maple (Acer pseudoplatanus) branches following their natural att...

For a sustainable environment, plant-growth-promoting rhizobacteria (PGPR) are natural resources considering as one of the most important fungicides’ alternatives inducing resistance to plant diseases. The aim present work is investigate synergistic promotion effect PGPR mixture composed Paenibacillus sp. strain B2 (PB2) and Arthrobacter spp. AA (AA), referred hereafter Mix-2, on wheat growth, ...

the sigatoka disease complex of banana involves three related ascomycetous fungi viz., mycosphaerella fijiensis, m. musicola, and m. eumusae. due to rather similar symptoms on banana, similar teleomorph morphology and problems associated with growth and sporulation in culture, species identification based on classical methods is troublesome. the exact distribution of these three species and the...
