“…We have no direct evidence, but the circumstantial probability does seem to exist. Structurally modified tolaasin peptides on the skin of mushrooms can be the result of co-colonisation by tolaasin detoxifying non-pseudomonads (Tsukamoto et al, 2002) and by either other mixed populations of Pseudomonas tolaasii variants or early colonisers such as Pseudomonas syringae species detected in cereal seeds used for mushroom spawn. Such activities are potentially capable of eliciting a differential response in interactive host A. bisporus cells.…”

New variants of pathogenic fungal viruses are emerging and they are enigmatic in revealing their molecular identity and of their origin. Double-stranded RNAs, some in non-encapsidated forms are increasingly becoming causal agents for sporadic diseases and are consistently associated with a complex profile of dsRNAs, presumably of (multiple) viral origin present in the host while the same are conspicuously absent in healthy (looking)

“…This highly specific strain (which does not infect the related P. ostreatus) forms an almost continuous layer of tightly aggregated cells around the hyphae. Toxic effects of the bacterial strain were evident by the swollen and vacuolated hyphal tips of the host, and the brown blotch symptoms appeared only when bacterial abundance exceeded 10 4 cfu g À1 d.w. Non-pseudomonads which detoxify tolaasin were identified by isolation techniques from fruitbodies of various wild mushrooms (Tsukamoto et al, 2002). The detoxifying bacteria are also attached to the surface of mycelia.…”

“…Some members of these two phyla are economically important sources of food and medicine for humans. Although mushrooms have one of the largest fruitbodies among fungi, potentially harboring highly diverse bacteria, evidence of their microbiome is limited and almost exclusively to taxa that grow in pure culture (Rangel-Castro et al, 2002a; Tsukamoto et al, 2002; Kumari et al, 2013). Only a few studies have analyzed mushrooms from different genera in this regard (Zagriadskaia et al, 2013; de Carvalho et al, 2015).…”

Bacterial Communities in Boreal Forest Mushrooms Are Shaped Both by Soil Parameters and Host Identity

Despite recent advances in understanding the microbiome of eukaryotes, little is known about microbial communities in fungi. Here we investigate the structure of bacterial communities in mushrooms, including common edible ones, with respect to biotic and abiotic factors in the boreal forest. Using a combination of culture-based and Illumina high-throughput sequencing, we characterized the bacterial communities in fruitbodies of fungi from eight genera spanning four orders of the class Agaricomycetes (Basidiomycota). Our results revealed that soil pH followed by fungal identity are the main determinants of the structure of bacterial communities in mushrooms. While almost half of fruitbody bacteria were also detected from soil, the abundance of several bacterial taxa differed considerably between the two environments. The effect of host identity was significant at the fungal genus and order level and could to some extent be ascribed to the distinct bacterial community of the chanterelle, representing Cantharellales—the earliest diverged group of mushroom-forming basidiomycetes. These data suggest that besides the substantial contribution of soil as a major taxa source of bacterial communities in mushrooms, the structure of these communities is also affected by the identity of the host. Thus, bacteria inhabiting fungal fruitbodies may be non-randomly selected from environment based on their symbiotic functions and/or habitat requirements.
