Climatic factors and pathogenic fungi threaten global banana production. Moreover, bananas are being cultivated using excessive amendments of nitrogen and pesticides, which shift the microbial diversity in plants and soil. Advances in high-throughput sequencing (HTS) technologies and culture-dependent methods have provided valuable information about microbial diversity and functionality of plant-associated endophytic communities. Under stressful (biotic or abiotic) conditions, plants can recruit sets of microorganisms to alleviate specific potentially detrimental effects, a phenomenon known as "cry for help". This mechanism is likely initiated in banana plants infected by wilt pathogen. Recently, reports demonstrated the synergistic and cumulative effects of synthetic microbial communities (SynComs) on naturally occurring plant microbiomes. Indeed, probiotic SynComs have been shown to increase plant resilience against biotic and abiotic stresses and promote growth. This review focuses on endophytic bacterial diversity and keystone taxa of banana plants. We also discuss the prospects of creating SynComs composed of endophytic bacteria that could enhance the production and sustainability of Cavendish bananas ( AAA), the fourth most important crop for maintaining global food security.
气候因素和致病真菌威胁着全球香蕉生产。此外，香蕉种植过程中使用了过量的氮肥和农药，这改变了植物和土壤中的微生物多样性。高通量测序（HTS）技术和基于培养的方法的进展，为植物相关内生群落的微生物多样性和功能提供了有价值的信息。在胁迫（生物或非生物）条件下，植物可以招募一组微生物来减轻特定的潜在有害影响，这种现象被称为“呼救”。这种机制可能在感染枯萎病原体的香蕉植株中启动。最近，有报道证明了合成微生物群落（SynComs）对自然存在的植物微生物群的协同和累积效应。事实上，益生菌SynComs已被证明可以提高植物对生物和非生物胁迫的恢复力并促进生长。本综述重点关注香蕉植株的内生细菌多样性和关键类群。我们还讨论了创建由内生细菌组成的SynComs的前景，这些SynComs可以提高香牙蕉（AAA）的产量和可持续性，香牙蕉是维持全球粮食安全的第四大重要作物。
