摘要
Plant immunity networks maintain microbial homeostasis in the phyllosphere, which in turn affects the plant health. Plant exudation and volatiles significantly shape the microbiome structure and composition. Various environmental stresses shape the complex interaction between phyllosphere microbiome and plant immunity. Understanding the molecular basis of plant–microbe and microbe–microbe interactions will help elucidate their impact on plant fitness. Recent advances utilizing synthetic microbial community combined with omics tools (such as metagenomics and metabolomics) provide important insights into the physiology and functionality of the phyllosphere microbiome. An integrated knowledge of multiomics combined with synthetic community approach can help determine the individual as well as community level contribution of phyllosphere microbiome in the host fitness. Microbiome engineering can reshape the microbial composition in the phyllosphere, and holds potential for large-scale microbiome research and reconfiguration of phyllosphere microbiome with desired traits to fight plant stresses. Phyllosphere microbial communities inhabit the aerial plant parts, such as leaves and flowers, where they form complex molecular interactions with the host plant. Contrary to the relatively well-studied rhizosphere microbiome, scientists are just starting to understand, and potentially utilize, the phyllosphere microbiome. In this article, we summarize the recent studies that have provided novel insights into the mechanism of the host genotype shaping the phyllosphere microbiome and the possibility to select a stable and well-adapted microbiome. We also discuss the most pressing gaps in our knowledge and identify the most promising research directions and tools for understanding the assembly and function of phyllosphere microbiomes – this understanding is necessary if we are to harness phyllosphere microbiomes for improving plant growth and health in managed systems.

Its mode of action does not depend on direct killing or inhibition of the invading pathogen, but rather on increasing physical or chemical barrier of the host plant. relating to or denoting an environment for rearing or culturing organisms in which all the microorganisms are either known or excluded. the study of microbes in their natural living environment, which involves the complex microbial communities in which they usually exist. the large-scale study of small molecules, commonly known as metabolites, within cells, biofluids, tissues or organisms. Collectively, these small molecules and their interactions within a biological system are known as the metabolome. the combination of metagenomics and metaproteomics that studies the whole genome and proteome; in this article this refers to studying the microbial community in order to understand their physiology. plants immediate defense response that recognizes pathogen-associated molecules and activates physical, chemical and cellular defenses against pathogens. the 0.5–4 mm soil zone surrounding plant roots that is strongly affected by root activities.
