Insights into the genetic basis of predator-induced response in Daphnia galeata.

ABSTRACT: Phenotypic plastic responses allow organisms to rapidly adjust when facing environmental challenges-these responses comprise morphological, behavioral but also life-history changes. Alteration of life-history traits when exposed to predation risk have been reported often in the ecological and genomic model organism Daphnia. However, the molecular basis of this response is not well understood, especially in the context of fish predation. Here, we characterized the transcriptional profiles of two Daphnia galeata clonal lines with opposed life histories when exposed to fish kairomones. First, we conducted a differential gene expression, identifying a total of 125 candidate transcripts involved in the predator-induced response, uncovering substantial intraspecific variation. Seco
