Figure 1. Differential seedling response to fructose signaling.

Figure 1

(A) WT (Ler), gin2, and HXK1 WT, S177A, and G104D-complemented gin2 showed seedling developmental arrest phenotypes on MS agar media containing 6% fructose. The seedlings were grown for 5 d under constant light. Scale bar, 5mm. (B) Unlike WT (Col), gin1 and ctr1 seedlings showed resistance to fructose. (C) CAB2 repression in the presence of high levels of glucose was de-repressed in gin2 seedlings, but not in the presence of high levels of fructose. Gene expression was measured in 5-d-old seedlings grown on MS agar media containing 6% glucose, fructose, or mannitol. (D) CAB2 expression was repressed by both glucose and fructose in WT, but not in gin1 and ctr1 seedlings. Values were normalized based on those obtained from seedlings grown on mannitol, and the means of triplicate measurements are shown with error bars. The experiments were repeated twice with consistent results.
