Gut microbiota mediating insect–plant interactions have many manifestations, either by provisioning missing nutrients, or by overcoming plant defensive reactions. However, the mechanism by which gut microbiota empower insects to survive by overcoming a variety of plant secondary metabolites remains largely unknown. Bactrocera minax larvae develop in immature citrus fruits, which present numerous phenolic compounds that challenge the larvae. To explore the role of gut microbes in host use and adaptability, we uncovered the mechanisms of phenol degradation by gut microbes using metagenomic and metatranscriptomic analyses, and verified the degradation ability of isolated and cultured bacteria. Research on this subject can help develop potential strain for the environmental friendly pest management operations.

肠道菌群宏基因组学和 Bactrocera minax（双翅目、实蝇科）苯酚降解的介导

肠道微生物群介导昆虫与植物的相互作用有多种表现形式，要么通过提供缺失的营养物质，要么通过克服植物的防御反应。然而，肠道微生物群通过克服多种植物次生代谢物使昆虫得以生存的机制仍然很大程度上未知。米纳克斯小实蝇幼虫在未成熟的柑橘类水果中发育，这些水果中含有大量的酚类化合物，对幼虫构成挑战。为了探讨肠道微生物在宿主利用和适应性中的作用，我们利用宏基因组和宏转录组分析揭示了肠道微生物降解苯酚的机制，并验证了分离和培养细菌的降解能力。该主题的研究有助于开发环境友好型害虫管理操​​作的潜在菌株。
