Apparently, climate change is observed in form of increased greenhouse gases (CH , CO , N O, CFC), temperature (0.5-1°C), and UV radiations (UV B and UV C). It is affecting every aspect of ecosystem functioning; however, terrestrial crops are the most vulnerable group and crop productivity largely remains a challenge. Due to climate change, seed yield and nutrient depletion are inevitable in future scenarios. To overcome this problem microbial groups that exhibit plant growth promoting attributes and provide protection against environmental stress should be studied. One such group is the pink pigmented facultative methylotrophs (PPFMs) that can induce overall fitness to plants. PPFMs are involved in phosphorous mineralization, siderophore, ACC deaminase, phytohormone production, and assimilation of greenhouse gases. Additionally, these organisms can also resist harmful UV radiations effectively as they possess polyketide synthases that could serve as source of novel bioactives that can protect plant from abiotic stress. The review article comprehensively highlights the multifunctional traits of PPFMs and their role in mitigating climate change with an aim to use this important organism as microbial inoculants for sustainable agriculture under climate-changing scenarios.
显然，气候变化表现为温室气体（CH、CO、NO、CFC）、温度（0.5-1°C）和紫外线辐射（UV B 和 UV C）的增加。它影响到生态系统功能的各个方面；然而，陆地作物是最脆弱的群体，作物生产力仍然是一个挑战。由于气候变化，未来的情景下种子产量和养分枯竭是不可避免的。为了克服这个问题，应该研究表现出促进植物生长特性并提供对环境胁迫保护的微生物群体。粉红着色兼性甲基营养菌（PPFM）就是这样一个群体，它可以提高植物的整体适应性。PPFM 参与磷矿化、铁载体、ACC 脱氨酶、植物激素的产生和温室气体的同化。此外，这些生物还可以有效地抵抗有害的紫外线辐射，因为它们拥有聚酮合酶，这些酶可以作为新型生物活性物质的来源，这些物质可以保护植物免受非生物胁迫。本文综述了 PPFMs 的多功能特性及其在缓解气候变化方面的作用，旨在将这一重要生物作为在气候变化情景下可持续农业的微生物接种剂加以利用。
