Fig. 1From: Identification and characterization of the Populus trichocarpa CLE familyMultiple sequence alignment of representative PtCLE proteins and the consensus sequence for the CLE motifs of poplar and Arabidopsis. a The multiple sequence alignment of representative PtCLE proteins. The predicted proteolytic cleavage sites are indicated by the small arrowheads. The CLE motif is boxed. b-c Weblogo plots were used for display the CLE motifs of poplar and Arabidopsis Back to article page
