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.
气候变化被视为一种自然灾害，它会导致生态系统波动、气温上升以及地球表面紫外线辐射（UV-A和UV-B）量增加。因此，诸如氯氟烃、甲烷、氮氧化物和二氧化碳等温室气体已成为可持续农业发展的障碍。为了克服诸如植物病原体、干旱、盐度、重金属以及高低温等环境压力，利用微生物是一个可行的选择。甲基营养型细菌合成的次生代谢产物可改善植物代谢、增强耐受性并促进生长。甲基杆菌属是一类粉红色色素的兼性甲基营养菌，由于甲醇的存在，它们大量定殖于植物，尤其是幼叶上。甲基营养型细菌产生的诸如氨基酸、类胡萝卜素、激素、抗菌化合物和其他化合物等次生代谢产物可在胁迫条件下增强植物代谢。因此，在本综述中，我们讨论了甲基营养型细菌产生的次生代谢产物的作用及其在胁迫条件下促进植物生长的作用。
