Evolutionary and diagnostic implications of intragenomic heterogeneity in the 16S rRNA gene in Aeromonas strains.

abstract：:Archaeal transcriptional machinery is similar to that of eukaryotes. We studied the fates of various components of the Sulfolobus solfataricus transcriptional apparatus under different stresses and found that in cells incubated at 90 degrees C for 1 h, transcription factor E (TFE) is selectively depleted, but its mRNA...
