Incoherent feedback from coupled amino acids and ribosome pools generates damped oscillations in growing E. coli

The paper develops a mechanistic model of bacterial growth that incorporates amino acid pools, ppGpp sensing, and transcriptional regulation, showing oscillatory dynamics during environmental changes.

Insulation of ribosomal promoter activity by Fis, H-NS or a divergent promoter within the packed E. coli genome.

The paper shows that Fis and H-NS insulation mechanisms and divergent promoters help regulate ribosomal promoter activity in E. coli, allowing gene duplication without local genomic effects.

Early fate of exogenous promoters in E. coli

The paper investigates the early expression dynamics of horizontally transferred genes in E. coli, finding that H-NS binding correlates with silencing while some promoters exhibit high noise due to transcriptional interference.

Genome size variation and species diversity in salamanders

This study examines genome size variation in salamanders, finding negative correlations between genome size and species richness at the family level, and associations with clade age and geographical/climatic factors.
