They allocate photosynthates to AM fungi in exchange for nutrients, thereby influencing plant fitness. Although plant phenotypes result from multiple traits constrained by trade-offs, the effects of AM fungi on plants are often studied using one trait. Plant response to AM fungi therefore needs to be analysed using multiple traits. Four Asteraceae species were inoculated with ten AM fungal strains using a factorial design in the greenhouse. The effect of AM fungal inoculation and their taxonomic identity on plants vegetative and reproductive traits were assessed. The predictability of the effects was evaluated based on AM fungal phylogenetic relatedness. The effect of the inoculation depended on the trait considered. Compared with the non-inoculated control, biomass allocation to roots decreased, while allocations to shoots or reproduction increased depending on the AM fungi or the plant. Significant differences were observed among AM fungi inoculates used, whether looking at separate traits, trade-offs between vegetative or reproductive growth, and the trait syndrome. In Centaurea cyanus, changes in plant phenotype were associated with the phylogenetic distance between AM fungi. These results underline the importance of using multi-trait approaches to understand AM fungal effects on plant phenotype. In accordance with the holobiont concept, the outcomes of this interaction depended on both the host plant and the AM fungus involved. It contributes to a better understanding of the biological effectors shaping the reaction norm (i.e., the range of phenotypic variation of a given host genotype) within the plant holobiont.","PeriodicalId":18965,"journal":{"name":"Mycorrhiza","volume":"35 3","pages":"40"},"PeriodicalIF":3.3,"publicationDate":"2025-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144226015","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}

Grapevine (Vitis vinifera), one of the most economically important crops worldwide, relies heavily on AM symbiosis for its growth and development. Since the phylloxera crisis, cultivated grapevines are obtained by grafting a Vitis vinifera scion onto a rootstock. In this study, we investigated the responses of the rootstock \"Riparia Gloire de Montpellier\" to mycorrhizal root colonization under three distinct phosphate (P) levels. We explored regulatory aspects of plant P nutrition by comparing the transcriptome profiling of non-colonized roots and roots colonized by the AM fungus Rhizophagus irregularis DAOM197198. We have shown that P availability significantly influences gene expression in both the AM fungus and the grapevine. Our transcriptomic study shed light on the molecular mechanisms that prevail during the AM symbiosis of a perennial woody plant species, with available P affecting several functional classes of proteins. The nine genes coding for Pht1 transporters in the R. irregularis genome were either down-regulated (RiPT1 and RiPT2) or up-regulated by the high-P treatment (RiPT8 and RiPT11), up-regulated by the low-P treatment (RiPT5), and regulated in a P-dose-dependent manner (RiPT9 and RiPT10). Expression of two of the three identified AM-induced Pht1, VvPT4 and VvPT8, was enhanced under mycorrhizal conditions, but finely tuned by the P treatment. To immunolocalize VvPT4 and VvPT8, we developed an innovative root-clearing protocol specifically designed for woody plants. This technological advancement has made it possible to visualize only VvPT4 at the periarbuscular membrane of mature arbuscules, its expression being strongly influenced by differences in P availability.","PeriodicalId":18965,"journal":{"name":"Mycorrhiza","volume":"35 3","pages":"39"},"PeriodicalIF":3.3,"publicationDate":"2025-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144160157","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}

However, they can affect non-target soil microorganisms, including arbuscular mycorrhizal (AM) fungi, that are potential indicators of the toxicity of pesticides on the soil microbiota. Here, we developed a fast-track high-throughput spore germination test, for AM fungi produced in vitro. This test allows the determination of EC50 values and the nature of the effects of pesticides on AM fungal spores (fungicidal or fungistatic). First, 19 active ingredients were tested on Rhizophagus intraradices MUCL 49410. Secondly, five of these compounds, varying in their toxicity to R. intraradices, were tested on three additional AM fungi (Rhizophagus irregularis MUCL 41833, Rhizophagus clarus MUCL 46238 and Rhizophagus aggregatus MUCL 49408). Our results showed that the toxicity of pesticides varied according to their chemical nature, concentration and AM fungal species tested. With the exception of 3,5,6-trichloro-2-pyridinol (TCP, a transformation product of chlorpyrifos), insecticides and herbicides had no detrimental effect on spore germination at the concentration expected in soil upon application of the recommended dose, unlike most fungicides, which had an impact on one or more AM fungi. Fludioxonil and pyraclostrobin were by far the most problematic fungicide and R. aggregatus the most sensitive strain to pesticides. This AM fungus could thus be a good indicator to be used in standard ecotoxicity testing. In conclusion, we present a fast-track, high-throughput testing system for assessing the toxicity of pesticides on AM fungi, using spore germination as a relevant endpoint, that could be used as a first-tier screening tool in pesticide risk assessment.","PeriodicalId":18965,"journal":{"name":"Mycorrhiza","volume":"35 3","pages":"38"},"PeriodicalIF":3.3,"publicationDate":"2025-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144079231","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}

We collected soil and rodent scat samples at five paired sites (i.e., disturbed vs. undisturbed) in Michoacan, Mexico. We identified 112 putative mycorrhizal fungi species using DNA barcoding based on partial internal transcribed region 1 (ITS) sequences. We found a higher richness of EMF in undisturbed soil samples compared to disturbed soil samples and a higher AMF diversity in rodent scat samples from disturbed than undisturbed sites. Scat samples had a high incidence of both AMF (75%) and EMF (100%). We found significant differences in the diversity of both AMF and EMF depending on the rodent species associated with them. We also found a higher diversity of EMF in scats in the wet season than in the dry season. We also report, for the first time, associations between Sigmodon hispidus and numerous AMF and EMF species.

Here, we report the first comprehensive morphological comparison of ectomycorrhizae among these four Tricholoma species. Several cultured strains of these species were inoculated onto Pinus densiflora in vitro. The resulting ectomycorrhizal pine seedlings were subsequently used as mother plants to establish an ectomycorrhizal system on Fagaceae plants. Although all tested fungal strains formed ectomycorrhizae on pine, mycorrhizal colonization by T. kakishimejioides was limited. On Quercus hosts, T. matsushimeji exhibited discontinuous Hartig net development, whereas T. kakishimeji and T. stans produced distinct Hartig nets. Additionally, ectomycorrhizal biomass development on oak hosts was limited in T. stans and T. matsushimeji. These findings correspond to the habitat characteristics of these fungal species. Ectomycorrhizae of these Tricholoma species sampled from natural forests showed morphological and anatomical characteristics similar to their in vitro ectomycorrhizae, including species-specific hyphal arrangements of the mantle and rhizomorphs.

Consequently, enhancing the salt tolerance of sugar beet is of paramount importance. Arbuscular mycorrhizal (AM) fungi form symbiotic associations with approximately 80% of vascular plants, thereby improving the adaptability of host plants to adverse conditions. However, the mechanisms by which the AM symbiosis assists sugar beet in coping with salt stress remain poorly understood. To investigate the adaptation strategies employed by AM symbiotic sugar beet under salt stress, we examined physiological and transcriptomic changes in sugar beet seedlings subjected to various treatments, using the KWS1176 variety as the experimental material. The results indicated that AM symbiotic sugar beet demonstrated superior performance under salt stress, characterized by improved seedling growth, alterations in antioxidant enzyme activities, modifications in osmoregulatory substance levels, reduced Na+ uptake, and enhanced K+ influx within the root system. Notably, most of the differentially expressed genes were implicated in pathways related to reactive oxygen species scavenging, phenylpropanoid biosynthesis, and phytohormone signal transduction. Furthermore, pivotal genes identified through weighted gene co-expression network analysis were validated via reverse transcription-quantitative PCR, revealing that the salt tolerance of AM symbiotic sugar beet may be associated with its ionic homeostasis, antioxidant enzyme activities, and regulation of photosynthesis at both transcriptional and physiological levels.","PeriodicalId":18965,"journal":{"name":"Mycorrhiza","volume":"35 3","pages":"35"},"PeriodicalIF":3.3,"publicationDate":"2025-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144010262","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}

Although mycorrhizal associations of its sister genus Gastrodia have been relatively well-studied, those of Didymoplexis remain largely unexplored. Here, we used molecular barcoding to analyze fungal associations and stable isotope analysis to elucidate the nutritional strategies of Didymoplexis micradenia, Didymoplexis pallens, and Didymoplexis siamensis in subtropical and tropical forests across Taiwan. In Didymoplexis pallens and Didymoplexis micradenia, most fungal partners were litter-decaying fungi (Mycena, Clitocybula, Marasmius, Gymnopus) with smaller contributions from ectomycorrhizal and rhizoctonia fungi. In Didymoplexis siamensis, ectomycorrhizal fungi dominated, particularly Sebacinales, however, with additional associations with wood-decaying Delicatula. The pattern of carbon and nitrogen isotope enrichments found for the three Didymoplexis species was in the typical range known for fully mycoheterotrophic orchids associated with litter- or wood-decaying fungi. 15N enrichments of all investigated Didymoplexis species distinguished from fully mycoheterotrophic orchids associated with ectomycorrhizal fungi. Despite its ectomycorrhizal association, Didymoplexis siamensis was weakly enriched in 15N and more enriched in 13C than found for exclusively ectomycorrhizal fully mycoheterotrophic orchids. Thus, Didymoplexis siamensis covered its carbon and nitrogen demand obviously through the additional association with wood-decaying Delicatula.
