1: Genes up-regulated in tendril tip vs. NS and up-regulated in tendril tip vs. center.

2: Genes up-regulated in tendril tip vs. NS and up-regulated in swarm center vs. NS.

3: putA was significantly up-regulated in tip cells vs. swarm center, but not tip cells vs. NS.

*: Genes up-regulated in tendril tip vs. NS only and expressed more than 1.3 log2-fold). Genes kept in our analysis since they are part of an operon or in certain cases, a pertinent cluster.
