Alteration in the leaf mesophyll anatomy by genetic modification is potentially a promising tool for improving the physiological functions of trees by improving leaf photosynthesis. Homeodomain leucine zipper (HD-Zip) transcription factors are candidates for anatomical alterations of leaves through modification of cell multiplication, differentiation, and expansion. Full-length cDNA encoding a  Eucalyptus camaldulensis  HD-Zip class II transcription factor (EcHB1) was over-expressed  in vivo  in the hybrid  Eucalyptus  GUT5 generated from  Eucalyptus grandis  and  Eucalyptus urophylla . Overexpression of  EcHB1  induced significant modification in the mesophyll anatomy of  Eucalyptus  with enhancements in the number of cells and chloroplasts on a leaf-area basis. The leaf-area-based photosynthesis of  Eucalyptus  was improved in the  EcHB1 -overexpression lines, which was due to both enhanced CO 2  diffusion into chloroplasts and increased photosynthetic biochemical functions through increased number of chloroplasts per unit leaf area. Additionally, overexpression of  EcHB1  suppressed defoliation and thus improved the growth of  Eucalyptus  trees under drought stress, which was a result of reduced water loss from trees due to the reduction in leaf area with no changes in stomatal morphology. These results gave us new insights into the role of the HD-Zip II gene.
