OmniSegger is an updated image analysis pipeline for bacterial cells that improves robustness to cell morphology and supports multiple imaging modalities, providing quantitative cellular analyses.

The paper develops a mathematical model to show that fitness maximization leads to protein overabundance, a transcriptional floor, and balanced transcription-translation load.

The paper investigates protein overabundance in Acinetobacter baylyi by analyzing proliferation dynamics of essential-gene knockouts, finding that most essential proteins are overabundant and that overabundance increases as expression levels decrease.

The paper identifies a conserved minimum transcription level of one message per cell cycle for essential genes across E. coli, yeast, and human, linking it to noise robustness.
