The fungus was originally isolated from the roots of Epidendrum nocturnum, a rupicolous orchid to the Brazilian Cerrado. In vitro assays demonstrated that W. circinata parasitized nematode eggs, with parasitism rates of 13-15% and characteristic emergence of septate hyphae with right-angle branching. Microscopy revealed eggshell degradation, arrested embryogenesis, and juvenile deformation. A mycelial suspension (MSF) of the fungus increased juvenile (J2) mortality in a dose-dependent manner, suggesting the action of nematicidal metabolites. In greenhouse experiments, W. circinata significantly reduced the nematode reproduction factor (RF), with values dropping from above 5 in the control to below 1 at the highest concentrations. In addition, MSF application promoted plant growth, increasing root length, root mass, and shoot height. No phytotoxic effects were observed at any dose. Principal component analysis confirmed a negative correlation between nematode-related variables and plant development, reinforcing the dual action of W. circinata in nematode suppression and plant stimulation. These effects are likely mediated by a combination of mechanisms, including parasitism, enzyme activity, antibiosis, and the production of phytohormones. The results highlight W. circinata as a promising candidate for the sustainable management of plant-parasitic nematodes and the enhancement of crop performance.","PeriodicalId":18965,"journal":{"name":"Mycorrhiza","volume":"35 6","pages":"60"},"PeriodicalIF":3.8,"publicationDate":"2025-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145308545","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By collecting lodgepole and ponderosa pine seedlings during their first growing season in recent clearcuts and burned areas, we were able to identify when colonization of pine roots first began, the rate at which ectomycorrhizal fungi colonized new germinants, and how this related to nitrogen nutrition and growth. Pine seedlings were first colonized in July, a month after germination was first observed. As the first seedlings became mycorrhizal, ectomycorrhizal lodgepole pine seedlings contained approximately 40% more nitrogen and > 60% greater biomass compared to uncolonized seedlings collected at the same time. Nitrogen content was 47% higher in mycorrhizal than nonmycorrhizal naturally-regenerating ponderosa pine seedlings. Ascomycetes, with a Pustularia sp. and Wilcoxina spp. most abundant, formed 80% of the ectomycorrhizae. Because all collected seedlings had ectomycorrhizae present on their roots by the end of the season, we concluded that inoculum of ectomycorrhizal fungi, especially of ruderal ascomycetes, was not limiting colonization of seedlings on these severely burned or recently clearcut sites. Our results are consistent with a role for ectomycorrhizal fungi in nitrogen acquisition, even within the first weeks after mycorrhiza formation; however, it is also possible that larger, more nitrogen-replete seedlings became colonized earlier than smaller seedlings.

Common mycorrhizal networks (CMNs), formed by arbuscular mycorrhizal fungi, facilitate inter-plant defense signal transmission. However, little is known about interspecies signal transmission through CMNs. This study aimed to investigate whether defense signals can be transferred from pathogen-infected white clover (Trifolium repens) to neighboring healthy perennial ryegrass (Lolium perenne) via CMNs and to assess the subsequent activation of disease-resistance responses in ryegrass at the transcriptional level. A dual-chamber experimental setup was used, in which white clover served as the donor plant and perennial ryegrass was the receiver plant. The results showed that pathogen-induced defense signals can be transferred from infected donor clover to healthy ryegrass plants through CMNs, inducing the expression of resistance genes in the neighboring plants, especially TRINITY_DN52759_c0_g1 (disease resistance protein RGA2). Importantly, the upregulated expression of defense genes was closely related to CAT activity. These factors enhance the defense response of neighboring healthy plants against potential pathogens. Although the pathogenic microbe evaluated is non-pathogenic to ryegrass, the signal transmission mechanism may apply to scenarios with shared threats. In addition, we identified gene modules significantly associated with CAT through weighted gene co-expression network analysis and screened key network genes (TRINITY_DN29267_c0_g1, TRINITY_DN37961_c0_g1, TRINITY_DN74958_c0_g2, TRINITY_DN7515_c0_g1, TRINITY_DN7587_c0_g6) in co-expression networks, which potentially play critical roles in defense responses. The findings suggest that CMNs serve as vital conduits for interplant defense signal transfer, facilitating early warning and defense activation against potential pathogens.","PeriodicalId":18965,"journal":{"name":"Mycorrhiza","volume":"35 5","pages":"55"},"PeriodicalIF":3.8,"publicationDate":"2025-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145137519","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Some proteins as such as flotilins or involved in the translational machinery were less-ubiquitinated, suggesting the facilitation of the de novo synthesis of proteins required to the establishment of arbuscular mycorrhizal symbiosis. In contrast, other proteins as transporters involved in plant nutrition through the direct pathway (i.e., MtPT5) and some enzymes involved in the lipid biosynthesis pathways were more-ubiquitinated, highlighting their putative degradation. In addition, Cdc48 protein accumulates in roots from 9 to 24 h post-inoculation, suggesting a role of Cdc48 in the transitory immune response during plant-fungal interactions.

Beta diversity analysis of the AM fungal community composition revealed that the factor species (agave/plantago) was significant (p = 0.0001), whereas the inoculum location was not (p = 0.29). The association of A. tequilana with AM fungi from the family Acaulosporaceae, as found in Mexican studies, could not be confirmed.

Therefore, the degree to which other ericaceous plants and ErMF form functional associations, and corresponding benefits for plant growth, are not well understood. As such, we lack a clear understanding of how changes in fungal partners may influence plant fitness. To address this gap, we conducted a greenhouse experiment with nine ericaceous plant species and eight ErMF isolates to expand baseline knowledge regarding the effects of the ErM symbiosis on host plant growth. By analyzing ErM root colonization and host plant growth response, we observed that the mycorrhizal growth response (MGR) was variable and depended on plant and fungal identity. Moreover, overall inoculation effects on plant growth were independent from colonization levels. Finally, we found evidence that MGR was influenced by plant phylogeny.

Here we investigated the influence of hyphal exploration and interaction with neighbouring mycorrhizal plants, plants that are weakly mycorrhizal, and a lack of neighbouring plants on the performance of Plantago lanceolata, a mycotrophic perennial herb common to many European grasslands, using mesh cores and the manipulation of neighbouring plant communities. Allowing growth of hyphae beyond the mesh core increased carbon capture above-ground and release below-ground as root exudates and resulted in the greater accumulation of elements relevant to plant health in P. lanceolata. However, contrary to expectations, the presence of mycorrhizal, or weakly mycorrhizal neighbours as well as an absence of neighbours did not significantly alter the benefits of hyphal networks to P. lanceolata. Our findings demonstrate that enabling the development of a fungal network beyond the immediate host rhizosphere significantly influences plant leaf elemental stoichiometry, enhances plant carbon capture, and increases the amount of carbon they release via their roots as exudates. Our experimental design also provides a simple set of controls to prevent attributing positive mycorrhizal effects to neighbouring plant connections.","PeriodicalId":18965,"journal":{"name":"Mycorrhiza","volume":"35 4","pages":"48"},"PeriodicalIF":3.8,"publicationDate":"2025-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12317909/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144768798","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
