Transcription profiling of juvenile Daphnia manga following exposure to various doses of Lufenuron, a benzoylphenylurea growth inhibitor (no RNA amplification)
Juvenile (<24hr old) Daphnia magna populations (n=250) were exposed (24hr) to Benzoylphenylurea growth inhibitor (14C labeled) lufenuron. Treatments were 0.15 ug/L, 0.33 ug/L, 0.65 ug/L lufenuron solvent control was 100 ul/L acetone carrier . Transcriptomic responses were screened using a D.magna cDNA microarray and the regulation of gene expression via log fold-change in transcript abundance, assessed. Genes involved in the synthesis of chitin were expected to respond to lufenuron, given the mode of action
