“…In a free air CO 2 enrichment experiment, Ren et al (2014) have also demonstrated important changes of phyllosphere bacterial communities in rice subjected to various combinations of elevated CO 2 and different levels of nitrogen fertilization. Conversely, enzymatic activities of phyllospheric microorganisms appear to act on important plant metabolites ( Huang et al, 2014 ), thus raising the possibility of complex feedback metabolic loops between plant tissues and phyllospheric microorganisms.…”

The phyllosphere, which lato sensu consists of the aerial parts of plants, and therefore primarily, of the set of photosynthetic leaves, is one of the most prevalent microbial habitats on earth. Phyllosphere microbiota are related to original and specific processes at the interface between plants, microorganisms and the atmosphere. Recent –omics studies have opened fascinating opportunities for characterizing the spatio-temporal structure of phyllosphere microbial communities in relation with structural, functional, and ecological properties of host plants, and with physico-chemical properties of the environment, such as climate dynamics and trace gas composition of the surrounding atmosphere. This review will analyze recent advances, especially those resulting from environmental genomics, and how this novel knowledge has revealed the extent of the ecosystemic impact of the phyllosphere at the interface between plants and atmosphere.Highlights• The phyllosphere is one of the most prevalent microbial habitats on earth.• Phyllosphere microbiota colonize extreme, stressful, and changing environments.• Plants, phyllosphere microbiota and the atmosphere present a dynamic continuum.• Phyllosphere microbiota interact with the dynamics of volatile organic compounds and atmospheric trace gasses.

“…Bacteria and fungi are the two most important microbiota groups that closely or loosely interact with plants in a beneficial or adverse manner. Plants and their associated plethora of microbes nurture multifactorial interactive relationships where specific microorganisms including bacteria and fungi can stimulate the biosynthetic and signaling pathways of the host plants for the production of pharmaceutically or agronomically important metabolic compounds (Scherling, et al, 2009 , van de Mortel, et al, 2012 , Huang, et al, 2014 , Ryffel, et al, 2016 , Pascale, et al, 2019 ). Recent literature has shown that root-associated microbes stimulate the systematically induced root exudation of metabolites (SIREM) process and affect levels of root transcriptomes and metabolomes (Korenblum, et al, 2020 ).…”

Background Cannabis growing practices and particularly indoor cultivation conditions have a great influence on the production of cannabinoids. Plant-associated microbes may affect nutrient acquisition by the plant. However, beneficial microbes influencing cannabinoid biosynthesis remain largely unexplored and unexploited in cannabis production. Objective To summarize study outcomes on bacterial and fungal communities associated with cannabis using high-throughput sequencing technologies and to uncover microbial interactions, species diversity, and microbial network connections that potentially influence secondary metabolite production in cannabis. Materials and method A mini review was conducted including recent publications on cannabis and their associated microbiota and secondary metabolite production. Results In this review, we provide an overview of the potential role of the soil microbiome in production of cannabinoids, and discussed that manipulation of cannabis-associated microbiome obtained through soil amendment interventions of diversified microbial communities sourced from natural forest soil could potentially help producers of cannabis to improve yields of cannabinoids and enhance the balance of cannabidiol (CBD) and tetrahydrocannabinol (THC) proportions. Conclusion Cannabis is one of the oldest cultivated crops in history, grown for food, fiber, and drugs for thousands of years. Extension of genetic variation in cannabis has developed into wide-ranging varieties with various complementary phenotypes and secondary metabolites. For medical or pharmaceutical purposes, the ratio of CBD to THC is key. Therefore, studying soil microbiota associated with cannabis and its potential impact on secondary metabolites production could be useful when selecting microorganisms as bioinoculant agents for enhanced organic cannabinoid production.

“…(2014) revealed significant changes in phyllosphere bacterial populations in rice treated to various combinations of high CO 2 and variable amounts of nitrogen fertilisation in a free air CO 2 enrichment experiment. In contrast, phyllospheric microorganisms' enzymatic activities appear to act on essential plant metabolites (Huang et al ., 2014), highlighting the prospect of complicated metabolic feedback loops between plant tissues and phyllospheric bacteria.…”

The complete aerial plant surfaces (above-ground sections) were referred to as the phyllosphere, which served as a microorganism home. On the leaf surface, microorganisms form compositionally complex communities. Bacteria, fungus, Actinomycetes, Cyanobacteria, and viruses abound in the phyllosphere's microbiome. The physiochemistry, habitat, and immunity of the host plant all influence the variety, dispersal, and community growth on the leaf surface. A colonisation process is a significant occurrence that benefits both the microorganism and the host plant. On the phyllosphere, microbes often establish either an epiphytic or an endophytic life cycle, which aids the host plant's functional communication with the surrounding environment. These communities regulate plant fitness, mediate foliar functional features, and contribute to a variety of ecological activities, including nutrient and water cycling. Beneficial microbes, can be used in agriculture to improve plant growth, health, and production. Growth-promoting bacteria and biocontrol agents isolated from the phyllosphere of various plant species have thus far been underutilised compared to those isolated from the soil or rhizosphere. Successful examples include the treatment of plant diseases, pathogen reduction, and nitrogen fixation in natural and agricultural systems. Based on existing research, this review gives a fundamental overview of the microbiome in leaf structure and it's physiology, microbial interactions, particularly among bacteria, fungus, and actinomycetes, and their adaptability in the phyllosphere environment. The work is the compilation of the importance of microbiome in the phyllosphere to the host plant and its surroundings which has been collected in detail and put together here.
