“…Presumably, once the inhibition effect is over, bacterial cells may recover the ability to reproduce and infect plant tissues. Further studies are scheduled in order to better clarify the span of the inhibition effect on leaves since the phyllosphere is a very complex environment where organic substances interact with a large number of biological and climatic variables, which could influence even their composition during time [97,98].…”

Hazelnut represents a relevant agro-food supply chain in many countries worldwide. Several biological adversities threaten hazelnut cultivation, but among them bacterial blight is one of the most feared and pernicious since its control can be achieved only by prevention through the observation of good agricultural practices and the use of cupric salts. The aim of this work was to evaluate the lignocellulosic biomasses obtained from hazelnut pruning and shelling residues as a renewable source of cellulose nanocrystals and lignin nanoparticles and to investigate their antimicrobial properties against hazelnut bacterial blight. Cellulose nanocrystals were obtained through an acid hydrolysis after a chemical bleaching, while lignin nanoparticles were synthesized by a solvent–antisolvent method after an enzymatic digestion. Both collected nanomaterials were chemically and morphologically characterized before being tested for their in vitro and in vivo antibacterial activity and biocompatibility on hazelnut plants. Results indicated the selected biomasses as a promising starting material for lignocellulosic nanocarriers synthesis, confirming at the same time the potential of cellulose nanocrystals and lignin nanoparticles as innovative tools to control hazelnut bacterial blight infections without showing any detrimental effects on the biological development of treated hazelnut plants.

“…secondary metabolites, anatomical structures) are contributing to the assembly of the studied communities (Parker et al 2015, Lajoie andKembel 2021). On the other hand, it is also possible that the evolution of fungal lineages has occurred in concert with the diversification of plant lineages (Arya andHarel 2019, Rutten et al 2021). The phyllosphere is a heterogeneous environment (Massoni et al 2020) and a key support for microbial diversity (Vorholt 2012), which constitutes a well-suited model system for the study of ecological concepts and theories (Meyer and Leveau 2012).…”

“…Research on phyllosphere microbial communities focuses mainly on taxonomic descriptions (Laforest‐Lapointe et al 2016), physiological processes (Carvalho and Castillo 2018), crop productivity (Arya and Harel 2019) and species ecology (Osono 2008, Qian et al 2020). The availability of massive sequencing techniques has opened the possibility to test ecological concepts and theories in this environment (Meyer and Leveau 2012).…”

The phyllosphere is a wide and complex ecosystem that provides a key support for microbial diversity. Fungal communities inhabiting the leaf are functionally variable and play important roles on plant performance. Factors conditioning the arrival and colonization of fungal communities will determine the phyllosphere fungal composition. Plant identity, leaf functional traits and host plant phylogeny have been shown to be regulators of the microbial colonization of the leaves, and can be considered as biotic filters determining the assembly of phyllosphere fungal communities. By high‐throughput sequencing we analysed the phyllosphere fungal communities from 38 Mediterranean woody plant species in two forests of south‐eastern Iberian Peninsula. We analysed the effect of plant species and site on fungal community composition. We also tested the effect of leaf functional traits and plant phylogeny on plant species differences in their fungal communities, and on the structure of the plant–fungus interaction network. Plant species account for a larger proportion than site in the variability of the composition of phyllosphere fungal communities. Leaf traits and host phylogeny influence the arrival and colonization of phyllosphere fungal communities across plant species. Plants with pubescent leaves and phylogenetically closer harbour more similar communities of decomposers, pathogens and epiphytes. Leaf habit (i.e. evergreen versus deciduous) also influences the community composition of decomposer and epiphytic fungi. Leaf carbon, leaf water content and leaf mass per area affect differentially each functional guild. Plant–fungus interaction networks present a modular structure in which plants belonging to the same module share more fungal species and are phylogenetically closer. We provide evidence that even though phyllosphere fungal communities are complex ecosystems, fungi with contrasting relationships with the plant (decomposers, epiphytes and pathogens) respond similarly to a common subset of leaf traits that impose physical limitations to the assembly of phyllosphere fungal communities.
