Heat map of the DEGs between WT and transgenic (PpEBB1-oe-3 and PpEBB1-oe-29) poplar plants mainly included cytokinin and auxin metabolism, cell cycle, and cell wall modification-related genes. The annotation of each gene was retrieved from https://phytozome.jgi.doe.gov/pz/portal.html#, and the abbreviated name is provided for reference. The qRT-PCR data for the heat map are the means of three replicates.
