Moreover, the corresponding enrichment or depletion patterns for 10 bacterial genera (59% of the 17 tested) to which the metabolite sensitive bacterial isolates belong were detected in the microbiota of at least one pathway mutant included in our microbiota analysis; the genera of bacteria for which growth is either promoted or inhibited by the triterpene cocktail mixture are depleted or enriched, respectively, in the pathway mutants compared with the wild type.

这段讲的是三萜在拟南芥根系微生物群中的影响做的是体外实验，分离了野生型拟南芥根系菌群，变量是加不加三萜

此外，我们在微生物群分析中发现了在代谢物敏感菌群中有10属的细菌（共17种，占比59%）至少存在一个通路产生了相应的增多/减少模式。相比于野生型细菌，这些突变体的生长会随着三萜混合物的增多/减少而受到抑制/促进。
