Fig. 1: Model of the effects of the AKT2var transgene in cassava, illustrating its role in increasing phloem transport rates.

The black lines represent K+ and sucrose (Suc) flows in wild-type plants, and the red lines represent these flows in AKT2var plants. In addition to endogenous AKT2, either phosphorylated or unphosphorylated, AKT2var is introduced to modify phloem transport rates in the stem by altering K+ partitioning. This modification is predicted to facilitate sucrose allocation to storage roots by increasing phloem sucrose loading and reloading efficiency. TP, triose phosphate.
