E. coli cultures were exposed to tellurite 0.5 µg/ml during 15 min. Total RNA was extracted and cDNA labeled probes were generated by reverse transcription using Alexa 555 and Alexa 647 fluorophores.
We applied metagenomics and metatranscriptomics to paddy soils with different As levels to investigate As resistance genes (ars) as well as respiratory oxidation (aioA) and reduction (arrA) genes to a
