With extraordinary global climate changes, increased episodes of extreme conditions result in continuous but complex interaction of environmental variables with plant life. Exploring natural phytomicrobiome species can provide a crucial resource of beneficial microbes that can improve plant growth and productivity through nutrient uptake, secondary metabolite production, and resistance against pathogenicity and abiotic stresses. The phytomicrobiome composition, diversity, and function strongly depend on the plant's genotype and climatic conditions. Currently, most studies have focused on elucidating microbial community abundance and diversity in the phytomicrobiome, covering bacterial communities. However, least is known about understanding the holistic phytomicrobiome composition and how they interact and function in stress conditions. This review identifies several gaps and essential questions that could enhance understanding of the complex interaction of microbiome, plant, and climate change. Utilizing eco-friendly approaches of naturally occurring synthetic microbial communities that enhance plant stress tolerance and leave fewer carbon-foot prints has been emphasized. However, understanding the mechanisms involved in stress signaling and responses by phytomicrobiome species under spatial and temporal climate changes is extremely important. Furthermore, the bacterial and fungal biome have been studied extensively, but the holistic interactome with archaea, viruses, oomycetes, protozoa, algae, and nematodes has seldom been studied. The inter-kingdom diversity, function, and potential role in improving environmental stress responses of plants are considerably important. In addition, much remains to be understood across organismal and ecosystem-level responses under dynamic and complex climate change conditions.
随着全球气候变化异常，极端天气事件增多，导致环境变量与植物生命持续但复杂的相互作用。探索天然植物微生物群落物种可以提供重要的有益微生物资源，这些微生物可以通过养分吸收、次生代谢产物产生以及对致病性和非生物胁迫的抗性来改善植物生长和生产力。植物微生物群落的组成、多样性和功能在很大程度上取决于植物的基因型和气候条件。目前，大多数研究都集中在阐明植物微生物群落中微生物群落的丰度和多样性，涵盖细菌群落。然而，对于了解整个植物微生物群落组成以及它们在胁迫条件下如何相互作用和发挥功能知之甚少。本综述确定了几个差距和关键问题，这些问题可以增进对微生物群落、植物和气候变化之间复杂相互作用的理解。强调利用天然存在的合成微生物群落的环保方法来增强植物的胁迫耐受性并减少碳足迹。然而，了解植物微生物群落物种在时空气候变化下参与胁迫信号传导和反应的机制极其重要。此外，细菌和真菌生物群落已被广泛研究，但与古菌、病毒、卵菌、原生动物、藻类和线虫的整体相互作用组很少被研究。跨王国的多样性、功能以及在改善植物环境胁迫反应中的潜在作用非常重要。此外，在动态和复杂的气候变化条件下，在生物个体和生态系统水平的反应方面仍有许多有待了解之处。
