Rootstock–scion combination contributes to shape diversity and composition of microbial communities associated with grapevine root system

“…Such variability in the relative abundance possibly occurs because such OTUs are differentially supported by specific combination of scion/rootstock genotypes. As suggested by Semchenko et al (2022), the identification of the factors that promote the plant association with microbial specialists and/or generalists will advance our understanding of the mechanisms regulating plant-soil feedback and of the ways plant-microbiome contributes to plant performances.…”

“…For example: Semchenko et al . (2022) convincingly challenge the assumption that microbially‐mediated plant–soil feedback is driven by specialism in plant–microbial interactions; and Weigelt et al . (2021) use belowground plant traits to assess aboveground–belowground trait coordination and identify an orthogonal ‘collaboration’ gradient, that is, the capability of outsourcing nutrient acquisition to collaborative fungal partners, within the range of global plant form and function.…”

Long-Term Fertilization Alters Mycorrhizal Colonization Strategy in the Roots of Agrostis capillaris

“…These, in exchange for a number of products assimilated by photosynthesis [14], protects against pathogens [15][16][17], limits abiotic stresses [18][19][20][21][22] and restricts the heavy metals of the host species [23][24][25]. In addition, mycorrhizal fungi interconnect with the grassland species through a network of hyphae [26], thus intervening in the dynamics of the plant community [27,28]. It has been shown that the involvement of plants in a symbiotic partnership with mycorrhizal fungi can lead to the dominance of some species, as well as to the exclusion of other plants [29][30][31].…”
