Asymmetric division and polar growth define a non-canonical cell cycle in Bradyrhizobium.

This study describes the asymmetric cell division and polar growth in Bradyrhizobium, revealing a unique cell cycle program with distinct nucleoid dynamics and chromosome organization.

Conserved lifestyle-associated chromosome architectures across mammalian symbionts

This study investigates chromosome organization in obligate mammalian symbionts, revealing conserved architectures linked to their lifestyle and growth conditions.

Bacterial chromatin remodeling associated with transcription-induced domains at pathogenicity islands

The paper investigates how SPI-1 activation in Salmonella remodels chromatin structure and regulates gene expression through H-NS and HilD interactions.

Stable chromosome configuration and loop-based polarization in animal symbionts

The paper studies chromosome organization in longitudinally dividing Neisseriaceae bacteria, finding that the origin of replication is at the host-attached pole and that loop-based folding occurs in specific contexts.

Ribosomal RNA operons define a central functional compartment in the Streptomyces chromosome

The paper shows that ribosomal RNA operons in Streptomyces define a central functional compartment in the chromosome, with dense core genes and high expression levels.
