Fig. 2From: Evidence for the role of transposons in the recruitment of cis-regulatory motifs during the evolution of C4 photosynthesisProportion of donors that were proximal to the acceptor. For each acceptor (X axis) and each potentially recruited bundle sheath-specific motif (colored block), the proportion of donors (colored segments along the Y axis) that were near to the acceptor in the chromosome where the acceptor gene resides is indicatedBack to article page
