  1. * The ssrA::mTn5 mutation [111] was transduced to SL1344 from strain P3F4 (12023 ssrA::mTn5).
  2. $ It should be noted that the polar mutation in STM0341 could affect expression of the downstream STM0342 gene; both of these genes are highly down-regulated during biofilm growth. Therefore, the putative periplasmic protein encoded by STM0342 may play a role in the phenotypes associated with strain JH3187.
