expression in Populus alba x Populus grandidentata causing an altered phenotype compared to the wild-type trees with altered timing of bud flush and leaf senescence. Tree height and stem diameter are similar to the wild-type, but differences in the length of xylem fibres occur. Elevated concentrations of intracellular sucrose in both leaf and stem tissue of the transgenic trees are associated with a prolonged onset of senescence and an advancement in bud flush in the following spring, phenotypes, overview | Arabidopsis thaliana |
