Extended Data Fig. 9. Gliding motility and T9SS phenotypes of mutant strains.

Footnotes for table:¹ Data from Fig. 4a.

² Activity of the major T9SS substrate chitinase in the extracellular medium. Includes data shown in Fig. 4b.

³ +++, spreads as well as the parental strain; ++ spreads less well than the parental strain; + residual spreading; - does not spread. Includes data shown in Fig. 4c.

⁴ Includes data from Supplementary Movie 1. Note that only strains possessing cell surface adhesins are able to adhere to glass slides, and that adhesin export to the cell surface requires the T9SS which in turn depends on functional GldLM.

⁵ Data from Fig. 4d.
