From: Identification and characterization of the Populus trichocarpa CLE family
Comparative studies of representative AtCLEs and PtCLEs with identical or nearly identical CLE motifs. Each subclade which contains a well-known AtCLEs (bold) and their closest poplar counterparts derived from the phylogenetic analysis of all AtCLEs and PtCLEs as depicted in Additional files 10 and 11. The identical residues are shaded in black while similar residues are shaded in grey. a The AtCLV3 clade; b The AtCLE1 clade; c The AtCLE10 clade; d The AtCLE41/TDIF clade
