  • To communicate with its brethren, it uses a molecule called acyl-homoserine lactone, or AHL.

  • N-acyl homoserine lactones (AHLs) for the coordination of gene expression.

  • N-acyl homoserine lactones (ALHs) to coordinate this behaviour - an early hint that bacteria are a talkative bunch.

  • In their system, a promoter DNA sequence (P luxI) drives the production of LuxI, an enzyme that synthesizes the quorum-sensing signal acyl-homoserine lactone (AHL).

  • Quorum sensing (via signals such as acyl-homoserine lactones) to act cooperatively. this would be group selection I'd say.
