Figure 4From: Molecular evolution and diversification of the Argonaute family of proteins in plants Relative residue bias (probability; lower panel) and relative evolution rate (upper panel) at functionally important positions in the three domains of AGOs in the plant kingdom. Relative frequency of each residue is represented by the height of the corresponding symbol. Height of the bar indicates the relative rate value for respective position. The positions marked with stars (in grey color) are the previously known signature residues.Back to article page
