An exciting future for microbial molecular biology and physiology | mBio
The first two bacterial genomes were sequenced nearly 30 years ago (1, 2). The cost of one of those sequences, that of Haemophilus influenzae, was over 1,000,000 U.S. dollars and took multiple years (...

We determine that additional pathogenic organisms also exhibit multicellular community formation in response to lysis. Given the pervasiveness of lysis in the environment, we propose that lysis sensing is a threat-agnostic mechanism by which bacteria can gauge endangerment. (4/4)

We identify the cell lysis signal as an abundant cytoplasmic polyamine, norspermidine, which is detected by an inner-membrane receptor, MbaA, that in turn drives biofilm formation. (3/4)

We find that the mechanism underlying this observation is a process we refer to as "lysis sensing"...whereby surviving cells sense a signal released by the death of their kin. (2/4)

Had a blast writing a commentary #msphere on “Biogeography of a human oral microbiome at the micron scale” by @jmarkwelch.bsky.social et al. The work in this paper made me want to be a microbiologist. I vividly remember an MBL lecture by Gary Borisy on the topic when I was a grad student.
