Figure 2.

Bacterial community composition in (A) glands of L. villosa beetles and (B) plant tissue that was exposed to the corresponding beetles, excluding samples that did not meet the threshold after chloroplast sequence removal. The relative abundance of bacterial amplicon sequence variants (ASVs) assessed at genus level by DADA2 analysis on the V4 region of the 16S rRNA gene is represented. Only the 30 most abundant bacterial ASVs for each corresponding sample type (glands or plants) are shown, and the remaining ASVs are grouped as “OTHER.” Beetle-associated ASVs are highlighted in color, and ASVs only associated to plants are depicted in grey. Genera names highlighted in bold correspond to identical ASVs in both gland and plant samples. NC = Negative control pools from plants that were not exposed to beetles.
