Bakhshi. M. 2019. A revision on the taxonomy of the genus Pseudocercospora. Plant Pathology Science 8(1):1-14. DOI: 10.2982/PPS.8.1.1.    Pseudocercospora species are plant pathogenic fungi occurring on a wide range of herbaceous and woody plants. Since its early description of the genus, its taxonomy has always been challenging. In recent years, Multi-gene DNA sequence data have provided sig...

the form and morphology criteria are among  effective components in enhancement and improvement of urban environments and one of the features of successful urban spaces, is the way these criteria are arranged alongside each other especially at the visual landscape of an entrance space, because entrance of every place is the first and most important communication ring between the person and the ...

The Myco silver nanoparticles (AgNPs) are synthesized through bio-reduction reaction of silver nitrate by cell-free filtrate of endophytic fungi, which act as both reducing and capping agent. The synthesis of silver nanoparticles (AgNPs) was confirmed through UV-VIS spectroscopy, Fourier Transform Infrared (FTIR), Transmission Electron Microscope (TEM), Scanning Electron Microscope (SEM). Energ...

Fungi are primary agents of organic matter decomposition in forests. Although invertebrate grazing affects fungal biomass and morphology, the species-specific consequences of these interactions are little understood. Using three collembola species (Folsomia candida, Protaphorura armata, Proisotoma minuta) we employed a multi-trophic approach to investigate the individual effects of invertebrate...

The few studies that have been carried out on deep-sea fungi in recent years either by culturing or molecular signatures, have provided evidence about their presence. A majority of culture-dependent and culture-independent fungi recovered showed homology to species reported in the terrestrial environment indicating their possible arrival in deep sea either with wind or terrestrial runoffs. Howe...

Changing climate is expected to alter precipitation patterns in the Arctic, with consequences for subsurface temperature and moisture conditions, community structure, and nutrient mobilization through microbial belowground processes. Here, we address the effect of increased snow depth on the variation in species richness and community structure of ectomycorrhizal (ECM) and saprotrophic fungi. S...

Elucidating symbiotic relationships between arbuscular mycorrhizal fungi (AMF) and plants contributes to a better understanding of their reciprocally dependent coexistence and community assembly. However, the main drivers of plant and AMF community assembly remain unclear. In this study, we examined AMF communities from 166 root samples of 17 woody plant species from 10 quadrats in a Chinese su...

The intraradical portion of arbuscular mycorrhizal (AM) fungi comprises mycelium, vesicles, and special physiological interfaces termed arbuscules; sometimes mycorrhizal fungi also produce spores within their hosts. Arbuscules are ephemeral structures that collapse after a few days, while the hyphae and vesicles appear to remain intact for some time after arbuscule senescence (post-arbuscule st...

Manganese (Mn) oxides are environmentally abundant, highly reactive mineral phases that mediate the biogeochemical cycling of nutrients, contaminants, carbon, and numerous other elements. Despite the belief that microorganisms (specifically bacteria and fungi) are responsible for the majority of Mn oxide formation in the environment, the impact of microbial spe­ cies, physiology, and growth sta...
