Note.—(A) Diploids A. halleri subsp. gemmifera genotype (Tada mine) and A. lyrata subsp. petraea genotype w1178. Allopolyploid genes significantly up- or down-regulated in A. halleri-derived (H-origin) and A. lyrata-derived (L-origin) homeologs for A. kamchatica genotypes (B) MUR (Murodo, Japan) and (C) PAK (Potter, Alaska). The significance threshold is set to a FDR-adjusted P < 0.05 and expression between control to zinc-treated conditions must add up to RPKM ≥ 0.2.
