The occurrence and amount of soluble and insoluble phenolics in mycorrhizal and non-mycorrhizal roots of Picea abies (L.) Karst, were investigated, p-Hydroxybenzoic acid glucoside, picein, piceatannol and its glucoside, isorhapontin, catechin and ferulic acid could be identified by high-performance liquid chromatography in mycorrhizas of Picea abies-Lactarius deterrimus and Picea abies-Laccaria amethystea. Both types were collected from axenic cultures and the latter also from a spruce stand… 

NOTAS CIENT˝FICAS MYCORRHIZAL COLONIZATION AND PHENOLIC COMPOUNDS ACCUMULATION ON ROOTS OF EUCALYPTUS DUNNII MAIDEN INOCULATED WITH ECTOMYCORRHIZAL FUNGI 1

The isolates from Eucalyptus seem to be more compatible towards E.†dunnii than those from Pinus, and the mechanisms involved could be related, at least in the cases of Pisolithus and Suillus, to the concentration of phenolics in roots.

The effect of the fungicide phosphite on ectomycorrhizal fungi

To determine if phosphite could have a direct inhibitory effect on the hyphae of ECM fungi, three isolates of Laccaria, Scleroderma and Pisolithus were grown in pure culture, on media containing a range of phosphite and phosphate concentrations.

Phenolic compounds in ectomycorrhizal interaction of lignin modified silver birch

The down-regulation of BpCOMT in the 35S-PtCOMT lines caused a reduction in the syringyl/guaiacyl ratio of lignin, but no significant effect was seen in the composition or quantity of phenolic compounds that would have been caused by the expression of PtCOMT under the35S or UbB1 promoter.

Mycorrhizal induction of phenolic compounds and antioxidant properties of fungi and seedlings during the early steps of symbiosis

The development of the ECM fungi, Paxillus involutus and Pisolithus arhizus, in the presence and the absence of the symbiont—Pinus pinaster—was evaluated as well as their antioxidant properties and phenolic compounds composition in response to the symbiotic association.

Effect of AM fungal association with normal and micropropagated plants of Andrographis paniculata Nees on biomass, primary and secondary metabolites

HPLC analysis of andrographolide revealed that Glomus fasciculatum treated micropropagated plants could synthesis higher percent of the active principle followed by normal plants inoculated with the same species of GlomUS.

Bioactive phenolic compounds, metabolism and properties: a review on valuable chemical compounds in Scots pine and Norway spruce

Phenolics and extracted phenolic compounds of Scots pine (Pinus sylvestris) and Norway spruce (Picea abies) show antibacterial activity against several bacteria. The majority of phenolic compounds

Detoxification of ferulic acid by ectomycorrhizal fungi

It is revealed that vanillic acid was less toxic than ferulic acid for Laccaria amethystina but that both phenolic acids were toxic for Lactarius deterrimus.

Early developmental stages of in vitro mycorrhization of Laccaria amethystea onPicea abies after short periods of incubation in growth chambers under elevated CO2 concentrations were studied and findings are discussed in respect to hydrophobins, which have recently been found to be expressed during early steps in ectomycorrhizal development.

This paper presents the results of literature studies conducted to systematise the knowledge on phenolic compounds found in trees and shrubs native to central Europe, and indicates gaps in the present knowledge.

It is suggested that accumulation of phenols in the epidermal cells of mycorrhizas is a response to the presence of the fungal symbiont, and features are discussed from the viewpoint that the outer cortical layer acts as a barrier to further hyphal penetration in E. fastigata.

Phenolics induced by L. laccata in the primary root are associated with resistance and may be the chemical basis for root protection and antibiosis was judged unimportant in root protection.
