The Role of torS and torT Transcription in Driving a Bet‐Hedging Strategy for Trimethylamine N‐Oxide Reductase Expression in Escherichia coli

open access: yesMolecular Microbiology, EarlyView.
Low basal activity of divergent promoters driving transcription of the trimethylamine N‐oxide (TMAO) sensor TorT and kinase TorS is integral to an O2‐regulated bet‐hedging strategy for continued E. coli growth upon the onset of anaerobiosis. This, along with repression by IscR, promotes noise in the TorS to TorT ratio, which is critical for adaptation ...

A Spontaneous Mutation in tfoX Impairs Bioluminescence in Photobacterium kishitanii ANT‐2200

open access: yesMolecular Microbiology, EarlyView.
A frameshift mutation in tfoX generates a truncated regulator associated with reduced lux–rib expression and low luminescence. Complementation with wild‐type tfoX restores transcription and light production, supporting a role for TfoX in regulating bioluminescence independently of quorum sensing.

Characterization of Sec14 Domain–Containing Proteins in the Malaria Parasite Plasmodium falciparum

open access: yesMolecular Microbiology, EarlyView.
During asexual blood‐stage development, P. falciparum Sec14 proteins display distinct localizations suggesting specialized roles in lipid exchange. PfSec14‐1 initially localizes to the nucleus before moving to the ER and Golgi alongside PfSec14‐4 during schizogony.

Plasmodium Actin‐Like Proteins 3 and 5a Are Required for Subsequent Steps of Mosquito Infection

open access: yesMolecular Microbiology, EarlyView.
Actin‐like proteins (Alps) are highly conserved, apicomplexan‐specific members of the actin superfamily. Using reverse genetics, we have identified that Alp3 and Alp5a are required at separate steps of transmission of the malaria parasite to its mosquito host.
