FIGURE 2.

Diurnal changes in starch (A) and sucrose (B) levels. Rice seedlings were grown in a growth chamber with a 12-h light (6:00–18:00)/12-h dark photoperiod. Temperature was maintained at 25°C during the light period and at 20°C during the dark period. White and gray bars represent light and dark periods, respectively. Fully expanded leaf blades of 3-week-old seedlings were harvested at designated times of the day and used for the measurements. Data represent the mean ± SE (n = 5) and the different letters indicate significant differences within each of the two lines, capital letters for WT and small letters for LSE1 (p < 0.05, Tukey’s test).
