Northwestern Medicine scientists have discovered how molecular "traffic controllers" in cells influence aging and cellular senescence—a state where cells stop dividing but remain metabolically active.

Mitochondrial transcription elongation factor maintains the balance between transcription and replication of mitochondrial DNA offering insights into potential treatments for mitochondrial disease and ...

According to this model, sigma (σ) factors bind to RNA polymerase to initiate transcription—the process by which genetic information is copied from DNA to RNA—and then detach after initiation to allow ...

Schematic model of PagKNAT5a-mediated xylem cell elongation and secondary cell wall formation. PagKNAT5a enhances longitudinal cell elongation in vascular tissues by modulating auxin accumulation.

New study reveals a key melon gene that controls fruit length, unlocking smarter breeding and potential nutritional gains.
