  1. Distances are shown for NSPs and ESPs which were identified as paralogous pairs. Note that of the A. thaliana NSP sequences, only AtNSP3 is included (see Tab. S4 for all comparisons). Amino acid distances are shown on the right, nucleotide distances on the left as determined by MEGA Vers. 5.05 [39] using the Equal-input + G model (daa) and the Kimura-Two-Parameter model + G + I (dna). Alignment gaps (e.g. JAL domains that are present only in NSPs) are regarded as non-informative posititions in this analysis. The very left column indicates the Brassicaceae lineage according to [33]. Protein abbreviations are as given in Table 1.
