Leaf carbohydrate controls over Arabidopsis growth and response to elevated
Transient starch production is thought to strongly control plant growth and response to elevated CO 2.We tested this hypothesis with an experimentally based mechanistic model in Arabidopsis thaliana.Experiments were conducted on wild-type (WT) A. thaliana, starch-excess (sex1) and starchless (pgm) mutants under ambient and elevated CO 2

Unraveling the role of transient starch in the response of Arabidopsis to elevated
Previous studies on Arabidopsis under long-term exposure to elevated CO2 have been conducted using starch synthesis and breakdown mutants cultured under short day conditions. These studies showed that starch synthesis can ameliorate the photosynthetic reduction caused by soluble sugar-mediated feedback regulation.
