From: Natural variation in stress response gene activity in the allopolyploid Arabidopsis suecica
Sister lines derived from the same allopolyploidization event display differential gene expression. Among the 148 (68Â +Â 38+ 2*21) differentially expressed genes (DEGs), 89 (68Â +Â 21) came from the A. thaliana subgenome, 59 (21Â +Â 38) came from the A. arenosa subgenome. Of these DEGs, 21 gene were differentially regulated in both subgenomes (homoeologous pairs). Interestingly, in all 21 cases both genes in homoeologous pairs were differentially regulated in the same direction (i.e. up or down)
