P7C: Mycorrhizal and endophytic fungal communities of TSPs (TreeDì_P7C Root fungi)

Tree species identity, plant successional stage, plant diversity level, and mycorrhizal type affect the soil microbial community composition. Plant genus diversity was also found to be an important predictor of ectomycorrhizal fungal community composition in subtropical forests. Both arbuscular and ectomycorrhizal fungal diversity and identity are known to influence tree species diversity and composition. Plant diversity level influences fungal community composition and the plant beta-diversity predicts the beta-diversity of fungal functional groups including mycorrhizal fungi. Despite the number of recent advances in the rhizosphere and endosphere microbiome research, there is a limited knowledge on the inter- and intra-kingdom variation in community composition, co-occurrence network patterns, the functional gene profiles, and the drivers of these network patterns and functional gene profiles in the interaction zones of mono- and hetero-specific tree species pairs. Objectives: Analyze how root associated bacterial and fungal community composition of mono- and hetero-specific TSPs change within and across diversity levels and environmental conditions Assess the link between root associated microbial communities with root traits, nitrogen acquisition and exudation profiles
