“…Other works reported either consistent findings (Mathimaran et al 2007) or contrasting results, showing that winter cover crops and subsequent crops shared similar AMF communities (Higo et al 2014(Higo et al , 2015. Possible explanations of changes in AMF species abundance found in our work may entail either host preference or seasonal variations.…”

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.

“…Especially the extra-radical hyphal length determination would be a good option to measure the AMF abundance in the soil, due to the fact that not all AMF produce spores (Morton and Redecker, 2001) and that would result in a limitation to the methods of spore count. Compared with fallow conditions, CC increased the root colonization of the subsequent crop in a temperate climate, for example, in maize Koide, 2000, 2002;Lehman et al, 2012;White and Weil, 2010), leeks (Sorensen et al, 2005) and soybean (Higo et al, 2014). However, other crops, such as sunflower, that are typical in rotations in Mediterranean areas have received no attention.…”

“…Thus, the climatic and environmental factors could be more important than winter cover cropping on AMF development (Higo et al, 2014). The effect of CC on AMF has been evaluated in various temperate areas in the USA (Galvez et al, 1995;Kabir and Koide, 2002;White and Weil, 2010) northwestern Europe (Sorensen et al, 2005) and Asia (Deguchi et al, 2007;Higo et al, 2014). Limited information about CC and AMF is available from Mediterranean areas and semiarid conditions.…”

“…However, in semiarid climates, the drier conditions generated by CC with respect to fallow (Gabriel et al, 2012) might be a limitation for the maintenance of potential AMF inoculum, affecting the process of colonization in the subsequent crop. Thus, the climatic and environmental factors could be more important than winter cover cropping on AMF development (Higo et al, 2014). The effect of CC on AMF has been evaluated in various temperate areas in the USA (Galvez et al, 1995;Kabir and Koide, 2002;White and Weil, 2010) northwestern Europe (Sorensen et al, 2005) and Asia (Deguchi et al, 2007;Higo et al, 2014).…”
