Scatter plot of nucleotide diversity (θ)in Ae. umbellulata (n = 12) and Ae. tauschii (n = 10) when 7666 transcripts derived from Ae. umbellulata KU-4017 were used as the references (a) and when 6622 transcripts derived from Ae. tauschii KU-2075 were used as the references (b). For both sets of transcripts, at least one of the species had polymorphisms. Scatter plot of gene expression (FPKM) in the 6062 orthologous pairs of Ae. umbellulata KU-4017 and Ae. tauschii KU-2075 retrieved by reciprocal best hits of BLAST analyses (c). Scatter plot of θ in the 3354 orthologous pairs of Ae. umbellulata KU-4017 and Ae. tauschii KU-2075 that had polymorphisms in one of the species (d). Kendall’s rank correlation (τ) for (a), (b), (c), and (d) was − 0.026 (p = 0.0033), 0.043 (p = 5.3e-6), 0.577 (p < 2.2e-16) and 0.049 (p = 0.0002), respectively
