Mycorrhiza is a mutualistic symbiosis between plants and fungi localized in roots or root like structures in which energy moves primarily from plants to fungi and inorganic resources move from fungi to plants. Mycorrhizal fungi may play important roles in nature. Findings of many researches are helpful in understanding the role of mycorrhizal fungi in the structure and functioning of ecosystems...
Fungi in soil play pivotal roles in nutrient cycling, pest controls, and plant community succession in terrestrial ecosystems. Despite the ecosystem functions provided by soil fungi, our knowledge of the assembly processes of belowground fungi has been limited. In particular, we still have limited knowledge of how diverse functional groups of fungi interact with each other in facilitative and c...
This paper reviews the potential of marine fungi in biotechnology. The unique physico-chemical properties of the marine environment are likely to have conferred marine fungi with special physiological adaptations that could be exploited in biotechnology. The emphasis of this review is on marine fungi from a few unique ecological habitats and their potential in biotechnological applications. The...
How soil fungi function in soil carbon and nutrient cycling is not well understood by using fungal enzymatic differences and their interactions with soil colloids. Eight extracellular enzymes, EEAs (chitinase, carboxymethyl cellulase, β-glucosidase, protease, acid phosphatase, polyphenol oxidase, laccase, and guaiacol oxidase) secreted by ten fungi were compared, and then the fungi that showed ...
Fungi are important components of every ecosystem. In nature, they play a significant role as decomposers, decomposing organic matter into simple compounds available for plants. They curious group organisms that attracts more and interest not only among mycologists phytopathologists, but also geneticists, biochemists physiologists. Metabolic products arboreal fungi show multidirectional action,...
The fungi are eukaryotic, unicellular, or multicellular organisms that, because they lack chlorophyll, are dependent upon external food sources. Fungi are ubiquitous in all environments and play a vital role in the Earth's ecology by decomposing organic matter. Familiar fungi include yeasts, rusts, smuts, mushrooms, puffballs, and bracket fungi. Many species of fungi live as commensal organisms...
Subtilases belong to a superfamily of serine proteases which are ubiquitous in fungi and are suspected to have developed distinct functional properties to help fungi adapt to different ecological niches. In this study, we conducted a large-scale phylogenomic survey of subtilase protease genes in 83 whole genome sequenced fungal species in order to identify the evolutionary patterns and subseque...
In recent years, marine fungi have become an important source of active marine natural products. Former researches are limited in habitats selection of fungi with bioactive compounds. In this paper were to measure antibacterial and antitumor cell activity for secondary metabolites of marine fungi, which were isolated from different habitats in coastal regions. 195 strains of marine fungi were i...
The infection structures, trophism, and ecological character of nematophagous fungi are reviewed in this article on the basis of data extracted from the literature and the most recent experiments conducted in this area. Traditionally, nematophagous fungi are classifi ed into four groups according to their modes of attacking nematodes: nematode-trapping fungi using adhesive or mechanical hyphal ...
Seeds of Haloxylon (H. pericae, H. aphyllum, and H. ammmodendron) were collected from Sabzevar and Gonabad regions. The seeds were kept in the refrigerator for isolation of the fungi after determining the germination rate and moisture content. The recommended methods by International Seed Testing Association (I.S.T.A.) for isolation of seedborne fungi were followed throughout this study. The fu...
