Escherichia coli σ38 promoters use two UP elements instead of a -35 element: resolution of a paradoxand discovery that σ38 transcribes ribosomal promoters

The paper resolves a long-standing paradox about σ38 promoters in E. coli by showing they use two UP elements instead of a -35 element and transcribe ribosomal promoters.

RNA polymerase organizes into distinct spatial clusters independent of ribosomal RNA transcription in E. coli

This study shows that RNA polymerase forms distinct spatial clusters in E. coli independent of rRNA transcription, with cluster organization influenced by nucleoid structure.
