Gene Structures, Classification, and Expression Models of the DREB Transcription Factor Subfamily in Populus trichocarpa

Figure 3

Locations of P. trichocarpa DREB genes on the chromosomes LGI-XIX. A schematic view of chromosome reorganization by recent whole-genome duplication in Populus is shown (adapted from [21]). Regions that are assumed to correspond to homologous genome blocks are shaded in the same color and connected with lines.
