MetabolomicsLipid biomarkers for algal resistance to viral infection in the ocean

Marine viruses play a key role in regulating phytoplankton populations, greatly affecting the biogeochemical cycling of major nutrients in the ocean. Resistance to viral infection has been reported for various phytoplankton species under laboratory conditions. Nevertheless, the occurrence of resi...

TranscriptomicsNascent elongating transcript sequencing (NET-seq) for Escherichia coli and Bacillus subtilis reveals a consensus pause sequence enriched at translation start sites.
Transcription by RNA polymerase (RNAP) is interrupted by pauses that play diverse regulatory roles. Although individual pauses have been studied in vitro, the determinants of pauses in vivo and their distribution throughout the bacterial genome remain unknown. Using nascent transcript sequencing we ...

TranscriptomicsTranscription profiling of E. coli K-12 W3110 strain grown at Ph5.7, 7.0, 8.5 reveals pH and anaerobiosis coregulate metabolism, multidrug transporters, and envelope composition
In Escherichia coli, pH-dependent gene expression varies with oxygen level. Anaerobic pH-dependent expression ratios were analyzed and compared to the published analysis of aerated cultures (Maurer et al, 2005). E. coli K-12 strain W3110 was cultured in closed tubes containing LBK broth buffered a...
