Fig. 3From: The DUB family in Populus: identification, characterization, evolution and expression patternsExon–intron distribution of Poplar trichocarpa DUB genes. The exon–intron distributions were sorted according to the UBP, UCH, OTU, MJD, and JAMM subfamilies. Coding sequence (CDS), intron, and upstream/downstream regions are indicated by a yellow rectangular box, black line, and blue rectangular box, respectivelyBack to article page
