Fig. 5From: Expression and regulatory asymmetry of retained Arabidopsis thaliana transcription factor genes derived from whole genome duplicationExpression partitioning between duplicate pairs with high regulatory asymmetry. Expression partitioning of three duplicate pairs KNAT3/4 (a), DAG1/2 (b), BCP2/3 (c) where the non-ancestral duplicate (blue arrow) exhibits differential function from the ancestral duplicate (red arrow). Expression quartile is indicated by color (dark green = 4th, green = 3rd, yellow = 2nd, white = 1st). Note that only expression conditions under which function differs between the duplicates are shownBack to article page
