Climate change is a natural disaster that leads to fluctuations in the ecosystem and an increase in temperature and UV radiation on the Earth's surface. Greenhouse gases, such as chlorofluorocarbons, methane, nitrogen oxide, and carbon dioxide, hinder sustainable agriculture. Using microorganisms to overcome environmental stress and enhance plant growth is a viable option. Methylobacterium, a pink-pigmented facultative methylotroph, produces secondary metabolites that improve plant metabolism and promote growth under stress conditions.
Climate change is considered a natural disaster that causes the ecosystem to fluctuate and increase temperature, as well as the amount of UV radiation (UV-A and UV-B) on the Earth's surface. Consequently, greenhouse gases such as chlorofluorocarbons, methane, nitrogen oxide, and carbon dioxide have become obstacles to the development of sustainable agriculture. To overcome environmental stress such as phytopathogens, drought, salinity, heavy metals, and high-low temperatures, the utilization of microorganisms is a viable option. The synthesis of secondary metabolites by methylotrophic bacteria improves plant metabolism, enhances tolerance, and facilitates growth. The genus Methylobacterium is a pink-pigmented facultative methylotrophs which abundantly colonizes plants, especially young leaves, owing to the availability of methanol. Secondary metabolites such as amino acids, carotenoids, hormones, antimicrobial compounds, and other compounds produced by methylotrophic bacteria enhance plant metabolism under stress conditions. Therefore, in this review, we discuss the role of secondary metabolites produced by methylotrophic bacteria and their role in promoting plant growth under stress.
