  • False discovery rate Q < 0.05.

  • a nc, noncoding; ns, nonsynonymous; syn, synonymous; utr, untranslated region.

  • b “At locus” refers to the locus tag for Arabidopsis thaliana.

  • c E-values from tBLASTx analysis of the loblolly pine EST contigs against the NCBI refseq RNA database for Arabidopsis.

  • d AI, aridity index.

  • e r2 is that from a general linear model with environment as the dependent variable and corrected genotypic values as explanatory variables.

  • f P-values listed in boldface type are also significant using a Bonferroni correction. Significance refers to the (Nk − 1)r2 statistic of Price et al. (2006).
