“…Pleurotus eryngii is a very important edible and medical mushroom that was an agaric basidiomycetes fungus of the genus Pleurotus (El Enshasy & Hatti‐Kaul, ). Pleurotus eryngii has become attractive as a functional food and source of drugs and nutraceuticals because it was rich in nutrients, including all amino acid required by the human body, and it was low in fat (Sheikh et al , ). Additionally, metabolites such as acids, terpenoids, polyphenols, sesquiterpenes, alkaloids, lactones, sterols, metal‐chelating agents, nucleotide analogues, vitamins and polysaccharide were essential bioactive substances present in this fungus (Kalogeropoulos et al , ; Kumar, ).…”

Pleurotus eryngii polysaccharide (PEP) was obtained using hot water extraction and ethanol precipitation. Three purified polysaccharide fractions (namely PEP1-A, PEP2-A and PEP3-A) were obtained from PEP using DEAE-cellulose-52 chromatography and a gel permeation Sephadex G-100 column. Firstly, this paper examined the characterisation of PEP1-A, PEP2-A and PEP3-A. The corresponding molecular weights were 5.378 9 10 5 , 9.506 9 10 6 and 4.975 9 10 5 Da, respectively. PEP1-A, PEP2-A and PEP3-A had similar monosaccharide compositions. PEP1-A was b-configuration, and PEP2-A and PEP3-A were a-configuration. PEP1-A, PEP2-A and PEP3-A had pyran-type rings, (1 ? 3) glucose and (1 ? 6) galactose linkages. Secondly, PEP, PEP1-A, PEP2-A and PEP3-A possessed antioxidant activities, and PEP was best. Therefore, only PEP was used to study its anti-fatigue activity in vivo. The result proved that PEP had anti-fatigue activity. PEP could be used as a valuable natural food supplement for preventing anti-fatigue or functional food.

“…Morels are rich in nutrition, contain a variety of active and flavor substances, and are the most famous edible fungus in the world (Sheikh et al, 2015 ; Sambyal and Singh, 2021 ). However, the unstable yield of morels has seriously hindered the healthy development of the morels industry.…”

Morels (Morchella) are one of the most popular edible fungi in the world, especially known for their rich nutrition and delicious taste. Earlier research indicates that the production of fruiting bodies can be affected by the growth of mycelium. To investigate the molecular mechanisms underlying mycelium growth in Morchella importuna, we performed transcriptome analysis and metabolomics analysis of three growth stages of the hypha of M. importuna. As a result, 24 differentially expressed genes, such as transketolase (tktA), glucose-6-phosphate dehydrogenase (G6PDH), fructose-diphosphate aldolase (Fba), and ribose-5-phosphate isomerase (rpiA), as well as 15 differentially accumulated metabolites, including succinate and oxaloacetate, were identified and considered as the key genes and metabolites to mycelium growth in M. importuna. In addition, guanosine 3′,5′-cyclic monophosphate (cGMP), guanosine-5′-monophosphate (GMP), and several small peptides were found to differentially accumulate in different growth stages. Furthermore, five pathways, namely, starch and sucrose metabolism, pentose and glucuronate interconversions, fructose and mannose metabolism, tyrosine metabolism, and purine nucleotides, enriched by most DEGs, existed in the three compared groups and were also recognized as important pathways for the development of mycelium in morels. The comprehensive transcriptomics and metabolomics data generated in our study provided valuable information for understanding the mycelium growth of M. importuna, and these data also unveiled the key genes, metabolites, and pathways involved in mycelium growth. This research provides a great theoretical basis for the stable production and breeding of morels.

“…Thus, V. bohemica was eventually recognized as an inedible mushroom [6]. Meanwhile, many studies have indicated that V. bohemica presents quite impressive antibacterial and antifungal activities [5], as well as strong antioxidant activities [7,8]. Furthermore, high contents of lovastatin, γ-aminobutyric acid (GABA), and ergothioneine have been found in mycelial and single-cell biomasses of V. bohemica, implying that the fungus possesses effective anti-inflammatory, antioxidant, profibrinolytic, and antihypertensive effects [9].…”

Verpa spp. are potentially important economic fungi within Morchellaceae. However, fundamental research on their mating systems, the key aspects of their life cycle, remains scarce. Fungal sexual reproduction is chiefly governed by mating-type genes, where the configuration of these genes plays a pivotal role in facilitating the reproductive process. For this study, de novo assembly methodologies based on genomic data from Verpa spp. were employed to extract precise information on the mating-type genes, which were then precisely identified in silico and by amplifying their single-ascospore populations using MAT-specific primers. The results suggest that the MAT loci of the three tested strains of V. bohemica encompassed both the MAT1-1-1 and MAT1-2-1 genes, implying homothallism. On the other hand, amongst the three V. conica isolates, only the MAT1-1-1 or MAT1-2-1 genes were present in their MAT loci, suggesting that V. conica is heterothallic. Moreover, bioinformatic analysis reveals that the three tested V. bohemica strains and one V. conica No. 21110 strain include a MAT1-1-10 gene in their MAT loci, while the other two V. conica strains contained MAT1-1-11, exhibiting high amino acid identities with those from corresponding Morchella species. In addition, MEME analysis shows that a total of 17 conserved protein motifs are present among the MAT1-1-10 encoded protein, while the MAT1-1-11 protein contained 10. Finally, the mating type genes were successfully amplified in corresponding single-ascospore populations of V. bohemica and V. conica, further confirming their life-cycle type. This is the first report on the mating-type genes and mating systems of Verpa spp., and the presented results are expected to benefit further exploitation of these potentially important economic fungi.
