Figure 5. Starch accumulates in N stressed cells.

Figure 5

A) Starch levels in cells harvested at LD 0 and LD 12. Results are mean ± SE (n = 3). Statistically different results (p<0.05) are marked using either a different letter (Analysis of variance) or an asterisk (Student's t-test). FW; Fresh weight. Bright-field microscopy of iodine-stained starch granules at day 0 (B–C), day 7 (D–E) and day 14-cells (F–G) at either LD 0 (B, D, F) or LD 12 (C, E, G). Starch is localized at the posterior part of the cells.
