DOI: 10.1038/s42003-020-01300-w
Abstract: Active dispersal of microorganisms is often attributed to the cells’ motile organelles. However, much less is known about whether sessile cells can access such motility through aggregation with motile counterparts. Here, we show that the… read more here.

DOI: 10.1093/nar/gky141
Abstract: Abstract High-resolution three-dimensional models of Caulobacter crescentus nucleoid structures were generated via a multi-scale modeling protocol. Models were built as a plectonemically supercoiled circular DNA and by incorporating chromosome conformation capture based data to generate… read more here.

DOI: 10.1099/mic.0.000753
Abstract: Vitamin B12 is one of the most complex biomolecules in nature. Since few organisms can synthesize B12de novo, most bacteria utilize highly sensitive and specialized transporters to scavenge B12 and its precursors. In Gram-negative bacteria,… read more here.

Methylation‐dependent transcriptional regulation of crescentin gene (creS) by GcrA in Caulobacter crescentus
Sign Up to like & getrecommendations! Published in 2020 at "Molecular Microbiology"
DOI: 10.1111/mmi.14500
Abstract: In Caulobacter crescentus the combined action of chromosome replication and the expression of DNA methyl‐transferase CcrM at the end of S‐phase maintains a cyclic alternation between a full‐ to hemi‐methylated chromosome. This transition of the… read more here.
