Carbohydrate levels in leaves of three different MP17:GFP transgenic Arabidopsis ecotypes

Leaf samples were harvested 7 h after beginning of the light period. Plants were grown for 5 weeks under SD conditions and samples were collected from fully expanded source leaves. Two samples were taken from each plant and averaged; values represent the mean ± se of 10 (Col-0 and Ler lines) or at least five (C24 lines) independent plants. Asterisks indicate statistical differences between transgenic lines and the respective wild type at *, P < 0.05; **, P < 0.01; and ***, P < 0.001 as determined by the Mann-Whitney U-test.
