Plants lack genetic resistance to most necrotrophic pathogens. To compensate for this disadvantage, plants recruit antagonistic members of microbiota to defend themselves against pathogens and other pests. Pseudomonas, Bacillus, and Trichoderma are well-known plant probiotic agents, which can protect plants against various biotic and abiotic stresses. In 2015, the Phytobiome initiative was launched by the White House. Phytobiomes consist of crops, the environment, and associated communities of microbes. Interkingdom interaction within the microbiome is dynamic and critical affecting crops and agroecosystem healthiness. In this presentation, a new probiotic strain Streptomyces, plant and environment factorial interaction, and the impact of the microbe in the agroecosystem will be introduced. Streptomyces is a gram-positive bacterium and more than two third of antibiotic compounds, currently used in the human clinic, are originated from the bacterium. However, in interaction with plant and agrosystem, the role and weight of Streptomyces is undervalued. Therefore, we recently start “STreptomyce in Agriculture Research” project with various cropping systems. Of special interest is that rhizosphere and anthosphere microbial community structures and shifting have been analyzed using massive pyrosequencing platforms. Based on the results, three putative probiotic Streptomyces strains have been isolated and characterized. The strains were well colonized in the rhizosphere, anthosphere, and phyllosphere. Unexpectedly, the three independent stains were revealed they had identical genome sequences. The following questions arise why the identical stains exist in totally different habitats and what is the function of the strains in such a system? In conclusion, Streptomyces is ubiquitous and unique in the system to provide a beneficial effect to both plant and it phytobiome communities. The STAR project will provide more opportunities and possibilities in agriculture.
