Figure 3.

Sequence similarities between algal PIPs and MIPEs in loop E. Figure showing iceLogos of part of Loop E for MIPEs, algal PIPs and P. patens PIPs. For each of the three groups compared, the iceLogo shows the position specific over- and under representations of amino acids compared to an alignment of all MIPs included in the phylogenetic analysis. Only amino acids significantly different in the test- and reference set (P < 0.05) are shown and the size of the character reflect the difference in frequency (positive values are overrepresented whereas negative values are underrepresented in the test set). At the bottom the amino acid sequence and numbering of SoPIP2;1 is shown to ease orientation.
