The general transcription elongation factor NusG functions as an intrinsic termination factor in Bacillus subtilis and together with NusA coordinates global gene expression including the motility regulon.
Temperature-dependent fasciation mutants of Arabidopsis unexpectedly connect mitochondrial RNA processing to the control of cell proliferation during lateral root morphogenesis via electron transport chain activity and reactive oxygen species production.
Yeast promoters can harbor multiple natural DNA variants that influence gene expression, interact genetically, evolve under negative selection, alter transcription factor motifs, and remain challenging to predict.
Human plasma contains protein-protected mRNA fragments, myriad repeat RNAs, and novel intron RNAs, including a family of structured full-length excised introns, some corresponding to mirtron pre-miRNAs and agotrons.
Unique 'true' S-cone and S-cone bipolar cell distribution patterns in the mouse retina are previously unappreciated anatomical features that support enhanced short-wavelength signaling for color detection above horizon.
