“…Without ectomycorrhizal (ECM) fungi, such as the widespread and species-rich genus Cortinarius [1], terrestrial ecosystems as we know them would not be able to exist. ECM fungi, which form complex structures within the roots of their symbiotic partner plants (= Hartig net) as well as an external multi-layered hyphal structure (= mantle/ sheath) [2], are the backbone of carbon and nutrient cycles in forests, as they are directly involved in the mobilization, absorption, and translocation of soil nutrients and water [3]. Some species, e.g., Tuber borchii and Lactarius bicolor, are even able to control root morphology via the formation of 2-(1H-indol-3-yl)-acetic acid and ethylene [4,5].…”

Mushrooms such as the dermocyboid Cortinarius rubrophyllus are characterized by strikingly colorful fruiting bodies. The molecular dyes responsible for such colors recently experienced a comeback as photoactive compounds with remarkable photophysical and photobiological properties. One of them—7,7′-biphyscion—is a dimeric anthraquinone that showed promising anticancer effects in the low nanomolar range under blue-light irradiation. Compared to acidic anthraquinones, 7,7′-biphyscion was more efficiently taken up by cells and induced apoptosis after photoactivation. However, seasonal collection of mushrooms producing this compound, low extraction yields, and tricky fungal identification hamper further developments to the clinics. To bypass these limitations, we demonstrate here an alternative approach utilizing a precursor of 7,7′-biphyscion, i.e., the pre-anthraquinone flavomannin-6,6′-dimethyl ether, which is abundant in many species of the subgenus Dermocybe. Controlled oxidation of the crude extract significantly increased the yield of 7,7′-biphyscion by 100%, which eased the isolation process. We also present the mycochemical and photobiological characterization of the yet chemically undescribed species, i.e. C. rubrophyllus. In total, eight pigments (1–8) were isolated, including two new glycosylated anthraquinones (1 and 2). Light-dependent generation of singlet oxygen was detected for the first time for emodin-1-O-β-d-glucopyranoside (3) [photophysical measurement: Φ∆ = 0.11 (CD3OD)]. Furthermore, emodin (7) was characterized as promising compound in the photocytotoxicity assay with EC50-values in the low micromolar range under irradiation against cells of the cancer cell lines AGS, A549, and T24.

“…Plants benefit from the symbiotic association also upon drought stress: AM fungi have been shown to modulate water loss in different crops [13, 14]. Similarly, ECM colonization of the root increases the plant water and nutrient supply [15], providing protection against soil pathogens [16].…”

Proteomics as a tool to decipher plant responses in arbuscular mycorrhizal interactions: a meta‐analysis

et al. 2023

The beneficial symbiosis between plants and arbuscular mycorrhizal (AM) fungi leads to a deep reprogramming of plant metabolism, involving the regulation of several molecular mechanisms, many of which are poorly characterized. In this regard, proteomics is a powerful tool to explore changes related to plant–microbe interactions. This study provides a comprehensive proteomic meta‐analysis conducted on AM‐modulated proteins at local (roots) and systemic (shoots/leaves) level. The analysis was implemented by an in‐depth study of root membrane‐associated proteins and by a comparison with a transcriptome meta‐analysis. A total of 4262 differentially abundant proteins were retrieved and, to identify the most relevant AM‐regulated processes, a range of bioinformatic studies were conducted, including functional enrichment and protein‐protein interaction network analysis. In addition to several protein transporters which are present in higher amounts in AM plants, and which are expected due to the well‐known enhancement of AM‐induced mineral uptake, our analysis revealed some novel traits. We detected a massive systemic reprogramming of translation with a central role played by the ribosomal translational apparatus. On one hand, these new protein‐synthesis efforts well support the root cellular re‐organization required by the fungal penetration, and on the other they have a systemic impact on primary metabolism.
