The paper quantifies the energetic cost of type IV pili (T4P) construction and operation across bacterial species, finding significant variation in energy investment.

The paper identifies how the Pil-Chp system regulates type IV pilus dynamics in Pseudomonas aeruginosa by modulating cAMP levels and affecting fiber length, count, and extension rate.

This study shows Pseudomonas aeruginosa uses energy-dependent T4P idling to balance dispersal and infection in fluctuating nutrient environments.

This study shows that pilus length in Pseudomonas aeruginosa determines virulence by revealing a hidden subpopulation of non-contributing filaments and shows extension dynamics, not retraction force, as the key constraint.

The paper identifies a prophage protein that modulates pilus dynamics to prevent phage progeny destruction, enhancing survival through quorum sensing.
