Figure 1

Diagram placing SPS in the context of cellulose synthesis. P-SuSy is shown as channeling UDP-Glc to the cellulose synthase (Amor et al., 1995; Haigler et al., 2001). This channeled UDP-Glc is labeled “no pool,” in contrast to the “free pool” of UDP-Glc that would support general metabolism and Suc synthesis within cellulose sink cells. Cofactors for enzymatic reactions are omitted from this diagram.
