Genomic organization of PtCLE genes. a The PtCLE gene structure is presented using gray boxes for exons, lines for the introns, and bold lines for UTRs, respectively. The black boxes mark the CLE motifs. b Physical locations of PtCLE genes on Populus chromosomes. The PtCLE genes are located according to the JGI Populus v2.2 gene annotation.
