“…Further analyses verified that Pseudomonas , Geobacter and Rhodoplanes were the main bacteria in Proteobacteria . We know that some strains of Pseudomonas had bio-control properties, such as killing parasitic fungi and some phytophagous nematodes [28], as well as stimulating hyphal growth, reducing ethylene production and inducing primordium formation of Agaricus bisporus [29]. However, Pseudomonas was the most common bacteria (5.52%) in the Zn∙Fe group (primordial differentiation stage), and this group also harvested the highest yield of ascocarps.…”

This study described the effects of elements (including Fe, Zn, Mn and their complexes) on the following factors in artificial morel cultivation: the characteristics of mycelia and sclerotia, soil bacterial community structures, yields and contents of microelements. The results indicated that the groups containing Mn significantly promoted mycelia growth rates, and all the experimental groups resulted in higher yields than the control (P<0.01), although their mycelia and sclerotia did not show obvious differences. It was also found that Proteobacteria, Chloroflexi, Bacteroides, Firmicutes, Actinobacteria, Acidobacteria and Nitrospirae were the dominated bacterial phyla. The Zn·Fe group had an unexpectedly high proportion (75.49%) of Proteobacteria during the primordial differentiation stage, while Pseudomonas also occupied a high proportion (5.52%) in this group. These results suggested that different trace elements clearly affected morel yields and soil bacterial community structures, particularly due to the high proportions of Pseudomonas during the primordial differentiation stage.

“…A model of synergism between bacteria and fungi has been postulated to occur within the casing material, in which native bacteria consume VOCs, and, therefore, stimulate fructification ( Fig. 1D; Noble et al, 2009;Chen et al 2013;Zang et al, 2016c).…”

“…As noted earlier, a decrease in the VOC concentration (primarily 1-octen-3-ol and ethylene) is considered as one of the environmental signals for induction of fruiting (Kuës et al, 2018). Native casing bacteria, such as P. putida, have been described to attach to the fungal hyphae and consume produced VOCs, and therefore stimulate and promote hyphal growth and primordium formation (Rainey et al, 1990;Rainey, 1991;Noble et al, 2009;Zarenejad et al, 2012;Chen et al, 2013;Colauto et al, 2016;Zang et al, 2016c). In support of this, the application of 1-octen-3-ol was shown to stimulate bacterial populations in the casing and of Pseudomonas spp.…”

“…specifically (Berendsen et al, 2013), with pseudomonads shown to increase their relative abundance in peat-based casing layer along the crop cycle (Carrasco et al, 2019). In addition, 1-aminocyclopropane-1-carboxylic acid (ACC) deaminase-producing bacteria within the casing layer have been reported to cleave ACC produced by the hyphae of A. bisporus, reducing the ethylene level surrounding mushroom hyphae, and relieving the inhibition of primordium initiation by ethylene (Chen et al, 2013;Zhang et al, 2016c). Hence, bacteria strains consuming VOCs could be suitable to be applied artificially in order to enhance fructification.…”

Growing edible mushrooms: a conversation between bacteria and fungi

Summary Mushroom cropping consists of the development and fructification of different fungal species in soil or selective substrates that provide nutrients and support for the crop. The microorganisms present in these environments strongly influence, and in some cases are required for the growth and fructification of cultivated mushrooms. Some fungi such as truffles and morels form ectomycorrhizal associations with host plants. For these fungi, helper bacteria play an important role in the establishment of plant‐fungal symbioses. Selective processes acting on the microbiota present in substrates and soils determine the composition of the microbiota inhabiting the fruit bodies or interacting with fungal hyphae, and both configure the mushroom holobiont, understood as the fungus plus associated microorganisms. Here, we review current knowledge regarding the cross‐talk between bacteria and fungi during mushroom cultivation. We highlight the potential use of bioinoculants as agronomical amendments to increase mushroom productivity through growth promotion or as biocontrol agents to control pests and diseases.

“…A few studies on fungal fruiting‐bodies suggest that bacteria may have important ecological roles in fungal spore dispersal (Splivallo et al ., ), gene expression (Riedlinger et al ., ; Deveau et al ., ) and mycotoxin production (Lackner et al ., ). In addition, bacteria may affect fungal growth (Chen et al ., ) and mycorrhization (Frey‐Klett et al ., ; Aspray et al ., ), yet we know little about the associated bacterial taxa and functions in epigeous fruiting‐bodies.…”

Recent advances in molecular methods have increased our understanding of various fungal symbioses. However, little is known about genomic and microbiome features of most uncultured symbiotic fungal clades. Here, we analysed the genome and microbiome of Inocybaceae (Agaricales, Basidiomycota), a largely uncultured ectomycorrhizal clade known to form symbiotic associations with a wide variety of plant species. We used metagenomic sequencing and assembly of dikaryotic fruiting-body tissues from Inocybe terrigena (Fr.) Kuyper, to classify fungal and bacterial genomic sequences, and obtained a nearly complete fungal genome containing 93% of core eukaryotic genes. Comparative genomics reveals that I. terrigena is more similar to ectomycorrhizal and brown rot fungi than to white rot fungi. The reduction in lignin degradation capacity has been independent from and significantly faster than in closely related ectomycorrhizal clades supporting that ectomycorrhizal symbiosis evolved independently in Inocybe. The microbiome of I. terrigena fruiting-bodies includes bacteria with known symbiotic functions in other fungal and non-fungal host environments, suggesting potential symbiotic functions of these bacteria in fungal tissues regardless of habitat conditions. Our study demonstrates the usefulness of direct metagenomics analysis of fruiting-body tissues for characterizing fungal genomes and microbiome.
