Using gene expression to test for mother-offspring interactions influencing development in Daphnia pulex
Ontology highlight
ABSTRACT: Understanding how maternal effects evolve requires a mechanistic understanding of how mothers influence the development of their offspring in different environments and over time, and how offspring respond to these effects, if at all. Here, we used functional genomics and a manipulation of mother and offspring food environments to assess to what extent the transcriptome of 3rd instar offspring is attributable to parental environment, offspring environment, or both in two Daphnia pulex clones isolated from the same natural population. Both clones demonstrated differential transcription in 3rd instar offspring in response to food availability, but the genes involved varied between clones. Maternal food environment had no effect on the transcriptome of offspring for either clone, irrespective of whether maternal and offspring environments were matched or mismatched. We discuss possible explanations for this finding and compare our results with those of similar studies using other systems.
