2 Figure 1 Self-poisoning leads to biofilm formation.
(A, B) Pseudomonas aeruginosa (green ovals) secretes the quorum-sensing molecule HQNO upon reaching high densities. (C) After HQNO accumulates, it inhibits bacterial respiration, causing bacterial death (dark gray ovals) and autolysis, releasing bacterial DNA. (D) The released DNA (shown as helical lines between bacteria) contributes to the biofilm matrix. Current Biology  , R80-R82DOI: ( /j.cub ) Copyright © 2016 Elsevier Ltd Terms and Conditions
