“…Accordingly, plasticity in the expression of a core set of plant genes has been detected in the interaction with different AMF taxa from Glomeraceae, Acaulosporaceae, Gigasporaceae and Diversisporaceae (Massoumou et al 2007;Feddermann et al 2008). Moreover, during plant/fungus interactions preceding the establishment of the symbiosis, chemical signals released by plant roots may differentially affect recognition process and colonization by different AMF symbionts (Giovannetti et al 1993;Akiyama et al 2005;Scervino et al 2005).…”

Arbuscular mycorrhizal fungi (AMF) establish mutualistic associations with the most important agricultural food and feed crops, sustaining plant growth, nutrient uptake and tolerance of biotic and abiotic stresses. Scanty information is available on the role played by crop identity and diversity as a driving force shaping AMF species communities in the field, in particular in low-input and organic farming, where crop rotation and the use of cover crops are common practices. Here, using a molecular approach, we investigated whether plant communities established in low and high diversity cover crop treatments affect the composition of native AMF root communities of subsequent maize in a Mediterranean organic agroecosystem. A total of 16 AMF sequence types were detected, with Acaulospora cavernata as the most abundant phylotype, accounting for 37.4 % of the sequences, followed by Funneliformis mosseae, Claroideoglomus lamellosum and Rhizoglomus intraradices. Sequences matching to Funneliformis caledonium, Diversispora aurantia, Diversispora epigaea and Archaeospora schenckii corresponded to less than 2.0 % of the total. The most abundant sequences retrieved in plants from cover crop treatments were represented by A. cavernata, while sequences in maize roots were related to F. mosseae, R. intraradices and Glomus sp. Such data show for the first time a change in the composition of native AMF communities colonizing maize roots, which was independent of the identity and diversity of the preceding crop. Our findings suggest that host preference may represent a strong driver of AMF community dynamics in agroecosystems, differentially boosting or depressing AMF species, possibly in relation to their functional significance.

“…95,97 This may be explained by specific effects of each flavonoid, as recently reported. 100,101 Therefore it is likely that the role of flavonoids is limited to a stimulatory effect on AM fungal growth 102 thereby facilitating encounters by the fungus with host roots as has been suggested for the role of stimulating microorganisms. A comparative study of flavonoids in Trifolium repens has shown that infection with a mycorrhizal symbiont (Glomus intraradices) can significantly alter the composition of flavonoids accumulated in roots.…”

“…Flavonoids were shown to stimulate spore germination, hyphal branching and root colonization (Kikuchi et al 2007;Scervino et al 2005Scervino et al , 2007Siqueira et al 1991;Steinkellner et al 2007). Among flavonoids in tomato root exudates, chrysin, luteolin and morin increased the number of entry points and the root colonization of Gigaspora rosea, Gigaspora margarita, Glomus mosseae, and Glomus intraradices, whereas kaempferol, isorhamnetin, and rutin showed no effect (Scervino et al 2007).…”

Flavonoids, one of the most-described group of plant "specialized metabolites", consist of more than 10,000 structurally diverse compounds. Most flavonoids accumulate in plant vacuoles as glycosides, with some released by the roots into rhizospheres. These flavonoids are involved in biological communications with rhizobia, arbuscular mycorrhizal fungi, plant growth promoting rhizobacteria, pathogens, nematodes, and other plant species. Both aglycones and glycosides of flavonoids are found in root exudates and in soils. This review describes researches on the mechanisms of flavonoid secretion and the fate of flavonoids released into rhizospheres. This review also discusses the direction of future research that may elucidate the specific roles of flavonoids in biological communications in rhizospheres, enabling the utilization of flavonoid activities and functions in agricultural practice.
