Figure 3. Alterations in leaf starch content of wild type and GWD mutants (gwd-c1, gwd-c2, sex1–8) grown in continuous light or transferred to a prolonged dark phase. (A) Wild type and mutants were cultivated in continuous light and samples were taken as indicated during the day. (B) Plants were grown in a strict 12 h light/ 12 h dark cycle for 5 weeks and at the end of the light phase subjected to a prolonged darkness. Data in (A) and (B) represent the mean ± SD of 3 independent biological replicates, each.
