Variability analyses of mitochondrial cytochrome oxidase I gene and of one nuclear microsatellite were performed for ten populations from the Ebro River and one from the Mijares River. Comparison of these results with those from five additional European populations indicated that the Spanish populations constitute a homogeneous gene pool. Transcriptome analyses of gill samples from a subset of the Spanish populations showed changes on expression levels that correlated with variations in general fitness and loads of heavy metals. The less polluted upstream Ebro populations showed overexpression of mitochondrial and cell proliferation-related genes compared to the more polluted, downstream Ebro populations. Our data indicate that heavy metals were the main factors explaining these transcriptomic patterns, and that zebra mussel is resilient to pollutants (like mercury and organochlorine compounds) proved to be extremely toxic to vertebrates. We propose that zebra mussel populations sharing a common gene pool may acclimate to different levels and forms of pollution through modulations in their transcriptomic profile, although direct selection on genes showing differential expression patterns cannot be ruled out. © 2013 Springer Science+Business Media New York This work was funded by Grants from the Spanish Ministry of Environment (042/RN08/03.4) and from the Spanish Ministry of Science and Innovation (CTM2011-30471-C02-01) Peer Reviewed 2014-01-21T11:01:20Z 2014-01-21T11:01:20Z 2013-07 2014-01-21T11:01:20Z artículo http://purl.org/coar/resource_type/c_6501 doi: 10.1007/s10646-013-1084-7 issn: 0963-9292 e-issn: 1573-3017 Ecotoxicology 22(5): 915-928 (2013) http://hdl.handle.net/10261/89666 10.1007/s10646-013-1084-7 en https://doi.org/10.1007/s10646-013-1084-7 none Springer
