“…1‐Octen‐3‐ol and ethylene have been described as VOCs secreted by the A. bisporus mycelium (Zang et al ., ; Meng et al ., ), which act to suppress the initiation of fructification (Noble et al ., ; Berendsen et al ., ; Eastwood et al ., , Meng et al ., ; Kües et al ., ). 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.…”

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.

“…The other ascomycetes: Aspergillus terreus [ 16 ], Botrytis cinerea [ 17 , 18 ], and Fusarium oxysporum [ 19 ], have the KMBA pathway for synthesizing ethylene. Similar to seed plants, the basidiomycetes Agaricus bisporus [ 20 , 21 ] and slime mold Dictyostelium mucoroides [ 22 ] synthesize ethylene via the ACC pathway.…”

The 1-aminocyclopropane-1-carboxylic acid (ACC) pathway that synthesizes ethylene is shared in seed plants, fungi and probably other organisms. However, the evolutionary relationship of the key enzyme ACC oxidase (ACO) in the pathway among organisms remains unknown. Herein, we cloned, expressed and characterized five ACOs from the straw mushroom (Volvariella volvacea) and the oyster mushroom (Pleurotus ostreatus): VvACO1-4 and PoACO. The five mushroom ACOs and the previously identified AbACO of the button mushroom contained all three conserved residues that bound to Fe(II) in plant ACOs. They also had variable residues that were conserved and bound to ascorbate and bicarbonate in plant ACOs and harbored only 1–2 of the five conserved ACO motifs in plant ACOs. Particularly, VvACO2 and AbACO had only one ACO motif 2. Additionally, VvACO4 shared 44.23% sequence identity with the cyanobacterium Hapalosiphon putative functional ACO. Phylogenetic analysis showed that the functional ACOs of monocotyledonous and dicotyledonous plants co-occurred in Type I, Type II and Type III, while putative functional gymnosperm ACOs also appeared in Type III. The putative functional bacterial ACO, functional fungi and slime mold ACOs were clustered in ancestral Type IV. These results indicate that ACO motif 2, ACC and Fe(II) are essential for ACO activity. The ACOs of the other organisms may come from the horizontal transfer of fungal ACOs, which were found ordinarily in basidiomycetes. It is mostly the first case for the horizontal gene transfers from fungi to seed plants. The horizontal transfer of ACOs from fungi to plants probably facilitates the fungal-plant symbioses, plant–land colonization and further evolution to form seeds.

“…How ethylene signaling plays a role in the senescence of mushrooms is unknown. Meng, Shen, Yang, Zhang, and Sheng () identified the gene encoding 1‐aminocyclopropane‐1 carboxylate oxidase, a key enzyme for ethylene synthesis, in A. bisporus , which indicated that similar to plants, ethylene in mushrooms is synthesized via the methionine cycle. Our unpublished data showed that ethephon treatment could accelerate the ripening and senescence of Chinese mushrooms.…”

The effects of paper containing different concentrations of 1‐methylcyclopropene (1‐MCP) on the quality of Chinese mushrooms were investigated. Mushrooms were first stored with paper containing 0, 0.25, 0.50, 0.75, 1.00, or 1.25 μl L−1 1‐MCP at 15 ± 1°C for 12 hr and then continued for up to 8 days. 1‐MCP reduced the respiratory peak, weight loss, degree of cap browning, relative leakage rate, and soluble solid content, and delayed the change in the surface hue angle. Mushrooms exposed to paper containing 1‐MCP maintained firmness and sensory attributes. The storage time of Chinese mushrooms treated with 1‐MCP at the best concentration (0.75 μl L−1) was 8 days, which was 4 days longer than that of the control. Browning in mushrooms was related to the vitamin C content, total phenol content, and polyphenol oxidase activity. The results would be very useful to the mushroom industry and provide a theoretical basis for the potential researches of the mechanisms maturation and senescence in Chinese mushrooms.
