Abstract

While the gut microbiome largely benefits host physiology, the impact of symbiosis on bacterial fitness has not been rigorously investigated. In this issue, Storelli et al. (2018) provide evidence that Drosophila actively cultivate a relationship with the growth-promoting bacterium Lactobacillus plantarum, delivering mutual benefits under nutrient-poor conditions.

摘要

虽然肠道微生物组在很大程度上有益于宿主生理学，但共生对细菌适应性的影响尚未得到严格研究。在本期杂志中，Storelli 等人（2018 年）提供了证据，表明果蝇主动与促进生长的细菌植物乳杆菌建立关系，在营养匮乏的条件下互利互惠。
