“…Elevated CO 2 can promote mycorrhizal colonization of plant roots as a consequence of the enhanced carbon allocation to roots ( Zhu et al, 2016 ; Asha et al, 2017 ), which may result in an increased mineral uptake from soil but not necessarily correlated with nutrient transfer to the host plant ( Smith and Read, 2008 ). Regarding the community composition of AMF, elevated CO 2 increased the ratio of Glomeraceae to Gigasporaceae but this effect may be masked by the natural changes through time ( Cotton et al, 2015 ) and also by the dependency of different fungi on water availability and precipitation ( Veresoglou et al, 2016 ).…”

Climate change and their resulting impacts are becoming a concern for winegrowers due to the high socioeconomic relevance of the winemaking sector worldwide. In fact, the projected climate change is expected to have detrimental impacts on the yield of grapevines, as well as on the quality and properties of grapes and wine. It is well known that arbuscular mycorrhizal fungi (AMF) can improve the nutritional quality of edible parts of crops and play essential roles in the maintenance of host plant fitness under stressed environments, including grapevines. The future scenarios of climate change may also modify the diversity and the growth of AMF in soils as well as the functionality of the mycorrhizal symbiosis. In this review, we summarize recent research progress on the effects of climate change on grapevine metabolism, paying special attention to the secondary compounds involved in the organoleptic properties of grapes and wines and to the levels of the phytohormones implied in the control of berry development and fruit ripening. In this context, the potential role of AMF for maintaining fruit quality in future climate change scenarios is discussed.

“…Nevertheless, this effect may be masked by the natural changes through time [45] and, also, by the dependency of different fungi on water availability and precipitation [46]. Elevated CO 2 can also indirectly promote the mycorrhizal colonisation of plant roots as a consequence of the enhanced carbon allocation to roots [47,48], but the positive effect of elevated CO 2 on root colonisation and the growth of extra-radical fungal hyphae has been mainly found in studies carried out in greenhouses rather than in the field [49]. Another indirect effect of climate change on AMF is due to changes in the soil properties and in the communities of other neighbouring microorganisms.…”

The association that many crops can establish with the arbuscular mycorrhizal fungi (AMF) present in soils can enhance the resistance of the host plants against several pathogens, including Verticillium spp. The increased resistance of mycorrhizal plants is mainly due to the improved nutritional and water status of crops and to enhanced antioxidant metabolism and/or increased production of secondary metabolites in the plant tissues. However, the effectiveness of AMF in protecting their host plants against Verticillium spp. may vary depending on the environmental factors. Some environmental factors, such as the concentration of carbon dioxide in the atmosphere, the availability of soil water and the air and soil temperatures, are predicted to change drastically by the end of the century. The present paper discusses to what extent the climate change may influence the role of AMF in protecting crops against Verticillium-induced wilt, taking into account the current knowledge about the direct and indirect effects that the changing environment can exert on AMF communities in soils and on the symbiosis between crops and AMF, as well as on the development, incidence and impact of diseases caused by soil-borne pathogens.

“…Changes in climate factors such as increasing CO2 concentration, increased temperature and changed precipitation pattern may have significant impacts on plant development and metabolism. The concentration of atmospheric CO2 has been progressively increasing from 280 ppm (pre-industrial era) in the year 1850 to 407 ppm in 2017 [2]. This created an attention towards the crop responses to enhanced CO2 levels and also to identify the responsive high yielding genotypes in order to enhance the productivity and production.…”
