“…spices). AMF influence the concentrations of several groups of plant metabolites such as alkaloids (Abu-Zeyad et al, 1999;Rojas-Andrade et al, 2003), terpenoids (Akiyama and Hayashi, 2002;Kapoor et al, 2002aKapoor et al, ,b, 2007Copetta et al, 2006;Jurkiewicz et al, 2010), carotenoids (Fester et al, 2002), flavonoids (Larose et al, 2002), glucosinolates (Vierheilig et al, 2000), and phenolic acids Jurkiewicz et al, 2010).…”

Arbuscular mycorrhizal (AM) are symbiotic systems in nature and have great significance in promoting the growth and stress resistance of medicinal plants. During our literature searchfrom the Chinese Scientific Information Database (Chinese National Knowledge Infrastructure, CNKI) we obtained 65 articles with "AM fungi" and "medicinal plant" as the key words, which indicates that in China, research efforts on these topics have been increasing. The main purposes of this review are to discuss the effects of mycorrhiza on the active ingredients of Chinese medicinal plants in comparison with results obtained in other plants in studies conducted by the international research community, and to introduce works published in Chinese journals to international colleagues.

“…Mycorrhizal colonization may induce quantitative and/or qualitative changes in plant secondary metabolite contents such as alkaloids (Abu-Zeyad et al 1999; Rojas-Andrade et al 2003); terpenoids (Maier et al 1997, 1999; Fester et al 1999; Akiyama and Hayashi 2002; Kapoor et al 2002a, b, 2007; Copetta et al 2006; Jurkiewicz et al 2010), including carotenoids (Fester et al 2002) and thymol derivatives (Zubek et al 2010); glucosinolates (Vierheilig et al 2000); phenolic compounds such as flavonoids (Morandi et al 1984; Larose et al 2002) and phenolic acids (Toussaint et al 2007, 2008; Ceccarelli et al 2010; Jurkiewicz et al 2010).

“…The mechanism of AMF-induced alterations in the phytochemical concentration in roots and/or shoots can be multidirectional (Toussaint 2007). Firstly, the modification of compound concentrations such as flavonoids and alkaloids in roots may be the consequence of signalling mechanisms between the host plant and fungi (Larose et al 2002; Rojas-Andrade et al 2003). Secondly, the alterations in the secondary metabolite balance can also result from plant response to AMF colonization.…”

Hypericin and pseudohypericin concentrations of a valuable medicinal plant Hypericum perforatum L. are enhanced by arbuscular mycorrhizal fungi

2011

Hypericum perforatum L. (St. John’s-wort, Hypericaceae) is a valuable medicinal plant species cultivated for pharmaceutical purposes. Although the chemical composition and pharmacological activities of H. perforatum have been well studied, no data are available concerning the influence of arbuscular mycorrhizal fungi (AMF) on this important herb. A laboratory experiment was therefore conducted in order to test three AMF inocula on H. perforatum with a view to show whether AMF could influence plant vitality (biomass and photosynthetic activity) and the production of the most valuable secondary metabolites, namely anthraquinone derivatives (hypericin and pseudohypericin) as well as the prenylated phloroglucinol—hyperforin. The following treatments were prepared: (1) control—sterile soil without AMF inoculation, (2) Rhizophagus intraradices (syn. Glomus intraradices), (3) Funneliformis mosseae (syn. Glomus mosseae), and (4) an AMF Mix which contained: Funneliformis constrictum (syn. Glomus constrictum), Funneliformis geosporum (syn. Glomus geosporum), F. mosseae, and R. intraradices. The application of R. intraradices inoculum resulted in the highest mycorrhizal colonization, whereas the lowest values of mycorrhizal parameters were detected in the AMF Mix. There were no statistically significant differences in H. perforatum shoot mass in any of the treatments. However, we found AMF species specificity in the stimulation of H. perforatum photosynthetic activity and the production of secondary metabolites. Inoculation with the AMF Mix resulted in higher photosynthetic performance index (PItotal) values in comparison to all the other treatments. The plants inoculated with R. intraradices and the AMF Mix were characterized by a higher concentration of hypericin and pseudohypericin in the shoots. However, no differences in the content of these metabolites were detected after the application of F. mosseae. In the case of hyperforin, no significant differences were found between the control plants and those inoculated with any of the AMF applied. The enhanced content of anthraquinone derivatives and, at the same time, better plant vitality suggest that the improved production of these metabolites was a result of the positive effect of the applied AMF strains on H. perforatum. This could be due to improved mineral nutrition or to AMF-induced changes in the phytohormonal balance. Our results are promising from the biotechnological point of view, i.e. the future inoculation of H. perforatum with AMF in order to improve the quality of medicinal plant raw material obtained from cultivation.

“…Among them the most important are arbuscular mycorrhizal fungi (AMF) and dark septate endophytes (DSE). In several stu dies, AMF and DSE have been found to enhance plant growth, photosynthetic activity, phosphorus content, act antagonistically towards soilborne fungal pathogens, and modify the concentration of plant metabolites [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17]. For this reason, the recognition of mycorrhizal status, monitoring of soil fungi and selection of beneficial microbial consortia to inoculate cultivated medicinal plants could be of particular value.…”

The material was collected from the section of medicinal plants of the Jagiellonian University Botanical Garden in Kraków. The garden holds a collection of approximately 200 medicinal plant taxa (E. Nowotarska personal communication, 2010). The selection of plant species was done mainly on the basis of their presence in Polish Pharmacopoeia [23], the importance of species for herbal industry (based on the amount Abstract Arbuscular mycorrhizal fungi (AMF) and dark septate endophyte (DSE) associations were studied in 36 medicinal plant species from 33 genera and 17 families, collected from the Botanical Garden of the Jagiellonian University in Kraków. Arbuscular mycorrhiza (AM) was found in 34 species (94%); 26 were of the Arum-type, 4 -Paris and 4 taxa revealed intermediate morphology. The abundance of AMF hyphae in roots varied with particular species, ranging from 2.5% (Helianthus tuberosus) to 77.9% (Convallaria majalis). The mycelium of DSE was observed in 13 plant species (36%), however, the percentage of root colonization by these fungi was low. Spores of 7 AMF species (Glomeromycota) were isolated from trap cultures established from rhizosphere soils of the investigated plants: Archaeospora trappei (Archaeosporaceae), Glomus aureum, Glomus caledonium, Glomus claroideum, Glomus constrictum, Glomus mosseae, Glomus versiforme (Glomeraceae). Our results are the first detailed report of root endophyte associations of the plant species under study. Moreover, the mycorrhizal status of 14 plant species is reported for the first time.
