The study on the design and regulatory effects of synthetic communities of endophytic actinomycetes of Salvia miltiorrhiza Bunge
Background
Microorganisms can confer or enhance various ecological adaptation functions of host plants, offering wide-ranging applications in the cultivation and production of medicinal plants. While root-associated beneficial actinomycetes are commonly used in biological control, their effects on plant growth and development have been rarely reported. This study focuses on a total of 13 beneficial endophytic actinomycetes in the roots of Salvia miltiorrhiza Bunge. Under different synthetic community (SynCom) construction principles, we constructed five synthetic communities based on functions and relationships to investigate their effects on growth, nitrogen metabolism, phosphorus metabolism, iron metabolism, resistance, and active components of S. miltiorrhiza.
Results
Synthetic communities 3 and 4 composed of functionally complementary strains promoted growth more effectively, synthetic communities 1 and 3 composed of distantly related strains increased total phenolic acid content, and synthetic community 5 that composed solely of indole-3-acetic acid (IAA)-producing strains not only promoted growth but also enhanced the active component content. Genome analysis revealed that synthetic communities with terpenes biosynthetic gene clusters promoted S. miltiorrhiza growth.
Conclusions
Our results suggested synthetic community design should consider strain relationships, plant growth-promoting (PGP) traits, and functional genes. This study introduces novel insights into synthetic community design.
期刊介绍：
Chemical and Biological Technologies in Agriculture is an international, interdisciplinary, peer-reviewed forum for the advancement and application to all fields of agriculture of modern chemical, biochemical and molecular technologies. The scope of this journal includes chemical and biochemical processes aimed to increase sustainable agricultural and food production, the evaluation of quality and origin of raw primary products and their transformation into foods and chemicals, as well as environmental monitoring and remediation. Of special interest are the effects of chemical and biochemical technologies, also at the nano and supramolecular scale, on the relationships between soil, plants, microorganisms and their environment, with the help of modern bioinformatics. Another special focus is the use of modern bioorganic and biological chemistry to develop new technologies for plant nutrition and bio-stimulation, advancement of biorefineries from biomasses, safe and traceable food products, carbon storage in soil and plants and restoration of contaminated soils to agriculture.
This journal presents the first opportunity to bring together researchers from a wide number of disciplines within the agricultural chemical and biological sciences, from both industry and academia. The principle aim of Chemical and Biological Technologies in Agriculture is to allow the exchange of the most advanced chemical and biochemical knowledge to develop technologies which address one of the most pressing challenges of our times - sustaining a growing world population.
Chemical and Biological Technologies in Agriculture publishes original research articles, short letters and invited reviews. Articles from scientists in industry, academia as well as private research institutes, non-governmental and environmental organizations are encouraged.
