Abstract
Fire blight disease caused by Erwinia amylovora has resulted in extreme economic losses to industrial plants of the Rosaceae family, including apples and pears, since the 1870s. Many countries have used pesticides and bactericides to manage the fire blight disease. However, chemical management leads to the emergence of a pesticide-resistant pathogen population. Therefore, attempts at managing the fire blight disease have been developed and applied using selected microorganisms as a biological control. However, a single strain of the biological control agent showed limited effect in reducing the disease. Here, we designed synthetic microbial communities (SynCom), which involve reconstituting multi-strains rather than relying on a single strain to enhance the disease control efficiency. We constructed the SynCom based on three categorized functions: i) anti-EA strain, ii) keystone taxa in healthy apples, iii) abundant metabolite strain in healthy apples than the fire blight infected apples. SynCom was significantly efficient in suppressing fire blight, achieving 0% disease severity in apple fruits, 1.67% in roses, and 5.4% in apple plants. Our finding presented that the well-designed SynCom showed significant effects in controlling the fire blight disease. Additionally, SynCom members should be selected based on multiple functions to maximize the impact on crop management.
期刊介绍:
The Journal of Microbiology and Biotechnology (JMB) is a monthly international journal devoted to the advancement and dissemination of scientific knowledge pertaining to microbiology, biotechnology, and related academic disciplines. It covers various scientific and technological aspects of Molecular and Cellular Microbiology, Environmental Microbiology and Biotechnology, Food Biotechnology, and Biotechnology and Bioengineering (subcategories are listed below). Launched in March 1991, the JMB is published by the Korean Society for Microbiology and Biotechnology (KMB) and distributed worldwide.
