Measuring transcriptional differences between Caulobacter crescentus cultured in nitrate versus ammonium as the sole nitrogen source

ABSTRACT: This study is measuring the steady-state levels of mRNA in wild-type Caulobacter crescentus grown in M2 defined medium containing either ammonium or nitrate as the sole nitrogen source. Four independent cultures of Caulobacter crecentus were grown in each of two medium conditions: M2(nitrate)glucose and M2(ammonium)glucose. Cultures in each medium type were grown to OD660=0.3 and RNA was isolated from each.

Toxin-antitoxin (TA) gene cassettes are widely distributed across bacteria, archaea and bacteriophage. The chromosome of the alpha-proteobacterium, Caulobacter crescentus, encodes eight ParE/RelE-superfamily toxins that are organized into operons with their cognate antitoxins. A systematic genetic analysis of these parDE and relBE TA operons demonstrates that seven encode functional toxins. The one exception highlights an example of a non-functional toxin pseudogene. Chromosomally encoded ParD a  ...[more]
