Extended Data Fig. 10: Summary of motor structures imaged by cryo-ET and mapped to bacterial species tree.

The phylogenetic tree in the center is derived from Fig. 6c. The motor structures investigated by cryo-ET are displayed on the periphery, with one representative species from each genus and taxon group labeled at the top of the image. Species names highlighted in blue indicate that their stator complexes are dynamic and invisible, while those marked in red represent that their stator complexes are visible. Potential E-ring is indicated by pink arrow and question marks in the image of Acetonema longum and Arcobacter butzleri mean that the position of E-ring is uncertain. Information of motor structure for species (follow a clockwise order) were taken from references: Acetonema longum¹, Leptospira interrogans⁸⁹, Borrelia burgdorferi^49,90, Treponema pallidum^91,92, Arcobacter butzleri⁹³, Campylobacter jejuni (this study), Wolinella succinogenes⁹³, Helicobacter pylori⁵⁰, Bdellovibrio bacteriovorus⁹³, Hyphomonas neptunium¹, Caulobacter crescentus⁹⁴, Bordetella bronchiseptica⁴⁷, Hylemonella gracilis¹, Legionella pneumophila², Pseudomonas aeruginosa², Shewanella oneidensis², Vibrio alginolyticus⁹⁵, Plesiomonas shigelloides⁹⁶, Salmonella enterica³, Escherichia coli⁹⁷.
