Web1 jun. 2024 · The paper L. Talà et al., “ Pseudomonas aeruginosa orchestrates twitching motility by sequential control of type IV pili movements,” Nat Microbiol, 4:774–80, 2024. Bacteria use long, threadlike attachments known as pili to interact with their environments. WebIn bacteria, reproduction can be very fast, with a generation taking little more than a few minutes for some species. This short generation time, together with random mutations and the mechanisms of genetic recombination we saw in this article, allow bacteria (and other prokaryotes) to evolve very quickly. Is that a good thing?
