Application

Application Comment Organism
additional information expression of the Arabidosis thaliana SPS gene in Populus alba x Populus grandidentata as model system for tree biology with substantial industrial relevance in the context of short rotation forestry and a target bioenergy crop Arabidopsis thaliana

Cloned(Commentary)

Cloned (Comment) Organism
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

General Information

General Information Comment Organism
physiological function SPS plays a crucial role in carbohydrate metabolism by regulating the partitioning of carbon between starch production and carbohydrate accumulation in many physiological and developmental processes, including responses to water stress, diurnal carbohydrate allocation within plants, and fruit and flower development Populus alba x Populus grandidentata
