When confronted with a selective challenge, theoretical and empirical results reveal that closely related taxa often evolve similar phenotypes from the same genes. However, evolutionary convergence on the genetic level is thought to be less likely in more distantly related species, because of differences in genetic background and a lack of shared standing variation, although this has not been tested at the genome scale. Here, we provide the first population genomic study of convergent local adaptation to the same climatic gradients between two species diverged for more than 140 million years, lodgepole pine (Pinus contorta) and interior spruce (Picea glauca, Picea engelmannii and their hybrids). Using sequence capture approach that targeted the exome of both species, we used environment allele associations, and phenotype allele associations to identify candidate regions of the genome associated with local adaptation to climate. Our comparative analysis of these regions finds that adaptation to temperature shows polygenic signatures of convergence at the phenotypic and genomic level. This suggests that adaptation to climate is somewhat genetically constrained, with key genes, particularly transcription factors, playing non-redundant roles.
