Widespread purine bias in bacterial genes driven by runaway transcription

The paper shows that purine bias in bacterial genes prevents premature transcription termination by evading Rho-dependent termination, leading to biased codon usage in species with runaway transcription.

Cell-scale gene-expression measurements in Vibrio cholerae biofilms reveal spatiotemporal patterns underlying development

This study uses smFISH to analyze gene expression in V. cholerae biofilms, revealing spatiotemporal patterns and the role of quorum sensing and c-di-GMP signaling in matrix gene expression.
