Amphioxus is exposed to 2 antibiotic treatments: chloramphenicol, and chloramphenicol + ampicillin. Tissues of the amphioxus digestive system from the pharyngeal gill slits to the intestine are collected after 0, 1, and 4 days, respectively. Total RNA is extracted, and the libraries are prepared and sequenced by Genome Analyzer IIx (Illumina).
