“…The accumulation of formononetin (an isoflavone) was significantly upregulated under the low phosphate treatment (Table S2), which supports the findings of Nair et al [20]. This compound has been shown to stimulate spore germination, hyphal growth and root colonization [20,71,72]. Genistein, another low phosphate-induced isoflavone, has also been shown to play an important role in promoting AM symbiosis development in tobacco roots [73].…”

A simulation of the environment inhabited by arbuscular mycorrhizal (AM) fungi could provide clues as to how to cultivate these obligate biotrophs axenically. Host intraradical and rhizospheric environments, root extracts and exudates in particular, would be crucial for AM fungi to complete their life cycles. In this study, we analyzed and compared the effects of root exudates (RE) and root extracts (RET) of white clover (Trifolium repens) on the asymbiotic growth of the AM fungus Funneliformis mosseae in vitro, and furtherly analyzed the chemical components of different RET with the LC-MS/MS technique in order to establish an asymbiotic cultivation system for this important and hardly domesticated AM fungus. RET is superior to RE in stimulating spore germination, hyphal elongation and branching, and secondary spore formation (p < 0.05). RET-induced effects were dependent on phosphate supplement levels, and the RET obtained following the treatment with low levels of phosphorus significantly promoted hyphal growth and sporulation (p < 0.05). A few newly formed secondary spores showed limited colonization of white clover roots. The low phosphorus-induced effects could be ascribed to the metabolic adjustment (mainly lipids and organic acids) of white clover roots under low phosphate conditions. Our findings demonstrate that the low phosphate-induced RET boosts the asymbiotic growth of AM fungus, and thus offers an alternative way to fulfill the life cycle of AM fungi asymbiotically.

“…The positive effects of the isoflavonoid formononetin on AMF colonization agrees with several studies that confirmed its potential to stimulate mycorrhization (Silva-Júnior and Siqueira, 1997;Siqueira et al, 1999;Soares and Martins, 2000;Catford et al, 2006;Cordeiro et al, 2015;Castillo et al, 2014;Ribeiro et al, 2016;Salgado et al, 2017;Savana da Silva et al, 2017). Some phenolic compounds are known to have an effect on different types of symbiosis in plants, such as formononetin of mycorrhiza (Siqueira, Safir and Nair, 1991).…”

“…The relationship between mineral P supply and mycorrhiza is extensively studied and frequently used as a classical example of antagonism (Bolan, 1991;Moreira and Siqueira, 2006;Smith et al, 2011;Liu et al, 2016;Motta et al, 2016;Savana da Silva et al, 2017). In this experiment, the inverse correlation between AMF root colonization to increased rates of P in the soil occurred as expected.…”

“…The level of root colonization found in this experiment can be considered adequate or comparable to field level results. As examples of AMF root colonization levels in soybean, Ferreira (2012) found a range between 63.3% and 69.5%; Cordeiro et al (2015) between 39% and 54%; Ribeiro et al (2016) and Savana da Silva et al (2017) between 55% and 66%.…”
