Fig. 3From: Defining novel plant polyamine oxidase subfamilies through molecular modeling and sequence analysisPhylogeny of plant PAOs subfamilies. The trees were constructed with maximum likelihood method. Nodes with Bootstrap support ≥85 are denoted by an asterisk. Aminoacid under the subfamily names indicates the residue present in the position corresponding to Glu60 of ZmPAO1. (a) Subfamily PAObc1. (b) Subfamilies PAOtc and PAObc3. (c) Subfamily PAObc2Back to article page
