Starch accumulation in transgenic GF14 antisense plants. Starch levels in wild-type (A) and GF14 ɛ (B) and μ (C) antisense plants grown under constant light were assayed by iodine staining. The density of staining clearly indicates increased starch levels in the leaves of antisense plants. Identical photographic lighting and exposure conditions were used for A–C so that the intensities of the staining are directly comparable. Similar plants were subjected to an 18-h dark period to allow for starch degradation before staining (D, E, and F, respectively), and the results indicate that starch degradation is uninhibited in the 14-3-3 antisense plants.
