The characteristics of plant-mycorrhizae associations are known to vary in both time and space, but the ecological consequences of variation in the dynamics of plant-fungus interactions are poorly understood. For example, do plants associate with single fungi or multiple fungi simultaneously, and do the associations persist through a plant's lifetime or do plants support a succession of differe...

Plants accommodate a specific microbiota on and in their roots that, similar to the microbial communities in human or animal guts, supports the host in nutrient acquisition (1). Beneficial associations with fungi are widespread in the plant kingdom and probably best known are so-called mycorrhizal symbioses (Fig. 1), which are formed between soil fungi and ∼90% of land plants (2). In these part...

Mycorrhiza is a mutualistic association between zone surrounding the root [2]. Although a lack in growth fungi and higher plants [1]. Different types of mycorrhizae response to VA-fungi inoculation in unsterilized soil was occur, distinguished by their morphology and to a also recorded, this result has been attributed to the fact certain extent, in their physiology. These include the that nativ...

Fifteen fungi were obtained from arsenic-contaminated agricultural fields in West Bengal, India and examined for their arsenic tolerance and removal ability in our previous study. Of these, the four best arsenic-remediating isolates were tested for plant growth promotion effects on rice and pea in the present study. A greenhouse-based pot experiment was conducted using soil inocula of individua...

Members of the sooty blotch and flyspeck (SBFS) complex are epiphytic fungi in the Ascomycota that cause economically damaging blemishes of apples worldwide. SBFS fungi are polyphyletic, but approx. 96% of SBFS species are in the Capnodiales. Evolutionary origins of SBFS fungi remain unclear, so we attempted to infer their origins by means of ancestral state reconstruction on a phylogenetic tre...

Fungi depend heavily on their ability to exploit resources that may become available to them in their myriad of possible lifestyles. Whether this requires simple uptake of sugars as saprobes or competition for host-derived carbohydrates or peptides, fungi must rely on transporters that effectively allow the fungus to accumulate such nutrients from their environments. In other cases, fungi secre...

Nitrogen isotopes (N/N ratios, expressed as dN values) are useful markers of the mycorrhizal role in plant nitrogen supply because discrimination against N during creation of transfer compounds within mycorrhizal fungi decreases the N/N in plants (low dN) and increases the N/N of the fungi (high dN). Analytical models of N distribution would be helpful in interpreting dN patterns in fungi and p...

This research is concerned with the fungicidal properties of nano-size silver colloidal solution used as an agent for antifungal treatment of various plant pathogens. We used WA-CV-WA13B, WA-AT-WB13R, and WA-PR-WB13R silver nanoparticles (AgNPs) at concentrations of 10, 25, 50, and 100 ppm. Eighteen different plant pathogenic fungi were treated with these AgNPs on potato dextrose agar (PDA), ma...

Plants simultaneously interact with multiple organisms which can both positively and negatively affect their growth. Herbivores can reduce plant growth through loss of plant biomass and photosynthetic area, while plant mutualists, such as mycorrhizal fungi, can increase plant growth through uptake of essential nutrients. This is the first study examining whether species-specific associations wi...

In this study, 36 extracts derived from 29 plant species selected using an ethnobotanical approach were tested for antifungal activity against a taxonomically diverse group of 13 human pathogenic fungi. We compared the inhibitory characteristics of these plant extracts with those of the commonly used antifungals, amphotericin B and ketoconazole, and the plant-derived antifungal, berberine. Seve...
