“…The results revealed that programmed cell death in M. sextelata was triggered by P. penicillatus infection via the upregulation of a chitin recognition protein, a caffeine-induced death protein, a putative apoptosis-inducing protein, and cyclin downregulation. Moreover, 1-octen-3-ol, a volatile mushroom compound with broad-spectrum antimicrobial activities, was shown to control the disease caused by P. penicillatus [ 41 ]. However, limited studies have focused on the mechanisms underlying red-stipe symptom occurrence.…”

The cultivation of true morels (Morchella spp., Morchellaceae, Ascomycota) has rapidly expanded in recent years, especially in China. Red stipe is a symptom wherein the stipe of morel fruiting bodies becomes red–gray, resulting in the gradual death of the affected fruiting bodies. The impact of red-stipe symptom occurrence on the development and nutritional quality of morel fruiting bodies remains unclear. Herein, morel ascocarps with the red-stipe symptom (R) and normal (N), artificially cultivated in the Fujian Province of China, were selected for the transcriptome and metabolome analysis to study the physiological and biochemical responses of morel fruiting bodies to the red-stipe symptom. Transcriptome data revealed several differentially expressed genes between the R and N groups significantly enriched in the tyrosine, riboflavin, and glycerophospholipid metabolism pathways. Similarly, the differentially accumulated metabolites were mainly assigned to metabolic pathways, including tyrosine, the biosynthesis of plant secondary metabolites, and the biosynthesis of amino acids. Moreover, the transcriptome and metabolome data combination revealed that tyrosine metabolism was the most enriched pathway, which was followed by ATP-binding cassette (ABC) transport, alanine, aspartate, and glutamate metabolism. Overall, the integration of transcriptomic and metabolomic data of M. sextelata affected by red-stipe symptoms identified several important genes, metabolites, and pathways. These findings further improve our understanding of the mechanisms underlying the red-stipe symptom development of M. sextelata and provide new insights into how to optimize its cultivation methods.

“…Moreover, in P. penicillatus, several CAZymes involved in the host cell wall degradation were upregulated. Furthermore, 1-octen-3-ol was found to reduce the severity of white mold disease by suppressing P. penicillatus in the soil and improving morel yields [ 41 ].…”

“…In addition, palmitic acid inhibits the activity of thyroglobulin, sodium iodide transporter, and thyroid peroxidase by reducing their expression, which indicates damage to thyroid hormone synthesis [ 24 ]. A higher essential oil component of T. triquetrum (L.) Ohashi, 1-octen-3-ol, showed broad-spectrum antibacterial activity in its previous volatile compound detection in mushrooms, in which 1-octen-3-ol exhibited effective inhibition of penicillium in soil, and could change the diversity of the soil bacterial community [ 25 ]. It is worth noting that 1-octen-3-ol can show strong antioxidant activity in plant extracts [ 26 ].…”

The present study aimed to determine the chemical compositions of essential oils (EOs) from Tadehagi triquetrum (L.) Ohashi and evaluate their antioxidant and anti-cholinesterase activity under the comprehensive influence of chemical components. The essential oils were extracted from T. triquetrum (L.) Ohashi by hydrodistillation. A total of 58 organic compounds were identified by GC-FID and GC-MS analysis. The major components of T. triquetrum (L.) Ohashi EOs were identified as palmitic acid (22.46%), 1-Octen-3-ol (14.07%), Caryophyllene (7.20%), (Z)-18-Octadec-9-enolide (6.04%), and 3-Hexen-1-ol (4.55%). The antioxidant activity of the essential oils was determined by using ABTS assay, DPPH assay, and FRAP assay, with IC50 values of 2.12 ± 0.05 mg/mL, 4.73 ± 0.91 mg/mL against the ABTS, DPPH, and FRAP value 117.42 ± 8.10 mM/g. The result showed that it had moderate antioxidant activities in the experiment, which why it is likely that it will be used as an antioxidant. At the same time, the EOs also showed moderate anti-acetylcholinesterase activity. This study expands the chemical and biological knowledge of the EOs of T. triquetrum.

“…Long-term continuous cropping affects soil microbial diversity and community composition, thereby leading to negative impacts on soil productivity and health [1,7]. Unlike most edible fungi, grown in pre-sterilized substrate packages, M. sextelata is cultivated directly into soil beds, hence its mycelial growth and fruiting are impacted by the interacting soil resident fungal community [1,2,8,9]. Previous studies have reported that morel yield was positively correlated with the alpha-diversity of the soil fungal community [8], and several prominent species act as soil-borne pathogens for black morels [1].…”

Decline in Morel Production upon Continuous Cropping Is Related to Changes in Soil Mycobiome

The black morel Morchella sextelata (Morchellaceae, Pezizales) is a valuable edible mushroom that can be cultivated on a large scale, but a severe yield decline is observed during continuous cropping. The effect of long-term cropping on soil-borne diseases and the dysbiosis of the microbiome and how these biotic factors affect the morel yield are not well understood. To help fill this knowledge gap, we designed an indoor experiment to investigate the influence of black morel cropping regimes on soil physicochemical properties, richness and distribution of fungal community, and morel primordial production. In this study, we employed rDNA metabarcoding and microbial network analysis to evaluate the effect of non-continuous and continuous cropping regimes on the fungal community during three developmental stages of black morel production, namely, the bare soil mycelium, mushroom conidial, and primordial stages. The results showed that during the first year, M. sextelata mycelium overwhelmed the resident soil fungal community by reducing the alpha diversity and niche breadth of soil fungal patterns by a greater amount compared to the continuous cropping regime, leading to high crop yield of 12.39 ± 6.09/quadrat but less complex soil mycobiome. To sustain continuous cropping, exogenous nutrition bags and morel mycelial spawn were consecutively added to the soil. The additional nutrient input stimulated the growth of fungal saprotrophic decomposers. The degrading activity of soil saprotrophs, including M.sextelata, caused a significant increase in soil nutrient content. This led to an inhibitory effect on the formation of morel primordia, resulting in a sharp decline to 0.29 ± 0.25/quadrat and 0.17 ± 0.24/quadrat, respectively, in the final morel cropping. Our findings provided a dynamic overview of the soil fungal community during morel mushroom production, allowing us to identify beneficial and detrimental fungal taxa in the soil mycobiome involved in morel cultivation. The information acquired from this study can be applied to mitigate the adverse impact of continuous cropping on the yield of black morel.
