“…First, common anthropogenic modifications can interactively control fungal community assembly ( 44 ), In this case, the phyllosphere habitat is more susceptible to anthropogenic influences compared to the root and soil habitats. Second, when the environmental conditions are spatially heterogeneous, increased stochasticity can reduce the importance of deterministic filters ( 44 ), and local environmental filtering (i.e., climate and/or plant traits) could have an important role in structuring fungal communities ( 45 ). Therefore, stochastic factors, such as random airborne dispersal, random disturbances, the priority effect, and atmospheric environmental conditions, such as solar radiation, humidity, and temperature, are critical for shaping the fungal communities that inhabit plant leaves ( 46 ).…”

“…We further found that warming influenced the fungal community composition, with a particularly strong effect towards the end of the growing season. In line with this finding, several observational studies have reported shifts in the composition of foliar fungal communities along altitudinal and elevational gradients, which are often used as proxies for changes in climate (Hashizume et al ., 2010; Cordier et al ., 2012; Davey et al ., 2013; Coince et al ., 2014; Whitaker et al ., 2018; Abrego et al ., 2020a,b; Cai et al ., 2020). However, findings along such gradients are often confounded by concurrent changes in abiotic and biotic environmental conditions.…”

Leaves interact with a wealth of microorganisms. Among these, fungi are highly diverse and are known to contribute to plant health, leaf senescence and early decomposition. However, patterns and drivers of the seasonal dynamics of foliar fungal communities are poorly understood.We used a multifactorial experiment to investigate the influence of warming and tree genotype on the foliar fungal community on the pedunculate oak Quercus robur across one growing season.Fungal species richness increased, evenness tended to decrease, and community composition strongly shifted during the growing season. Yeasts increased in relative abundance as the season progressed, while putative fungal pathogens decreased. Warming decreased species richness, reduced evenness and changed community composition, especially at the end of the growing season. Warming also negatively affected putative fungal pathogens. We only detected a minor imprint of tree genotype and warming × genotype interactions on species richness and community composition.Overall, our findings demonstrate that warming plays a larger role than plant genotype in shaping the seasonal dynamics of the foliar fungal community on oak. These warminginduced shifts in the foliar fungal community may have a pronounced impact on plant health, plant-fungal interactions and ecosystem functions.

“…Environmental parameters are also key factors that cause changes in the endophytic community ( Carper et al, 2018 ; Bei et al, 2019 ; Chen et al, 2019 ). Climate characteristics, soil nutrients and vegetation composition change along altitude gradients may cause variations in the endophytic community ( Cai et al, 2020 ; Zarraonaindia et al, 2015 ). Plant species and altitude significantly affected the root endophytic bacterial and fungal community composition in the present study.…”

Plant adaptation under climate changes is critical to the maintenance of terrestrial ecosystem structure and function. Studying the response of the endophytic community to climate warming is a novel way to reveal the mechanism of host environmental adaptability because of the prominent role endophytes play in host nutrient acquisition and stress tolerance. However, host performance was generally neglected in previous relevant research, which limits our understanding of the relationships between the endophytic community and host responses to climate warming. The present study selected two plants with different responses to climate warming. Elymus nutans is more suitable for growing in warm environments at low altitude compared to Kobresia pygmaea. K. pygmaea and E. nutans were sampled along an altitude gradient in the natural grassland of Qinghai-Tibet Plateau, China. Root endophytic bacterial and fungal communities were analyzed using high throughput sequencing. The results revealed that hosts growing in more suitable habitats held higher endophytic fungal diversity. Elevation and host identity significantly affected the composition of the root endophytic bacterial and fungal community. 16S rRNA functional prediction demonstrated that hosts that adapted to lower temperatures recruited endophytic communities with higher abundance of genes related to cold resistance. Hosts that were more suitable for warmer and drier environments recruited endophytes with higher abundance of genes associated with nutrient absorption and oxidation resistance. We associated changes in the endophytic community with hosts adaptability to climate warming and suggested a synchronism of endophytic communities and hosts in environmental adaptation.
