Starch accumulation in CRCT transgenic lines analyzed by iodine staining. A, Starch accumulation of leaf blade (top) and leaf sheath (bottom). Sixth leaf blade and fifth leaf sheath at the 6.5 leaf stage were sampled at the end of the light period and stained by iodine solution. B, Iodine staining of starch in glumaceous flower including anther (top), culm of heading stage (middle), and root at seedling stage (bottom). OX1 and OX2 indicate CRCT overexpression lines, and RNAi1 and RNAi2 indicate CRCT knockdown lines. LS, Leaf sheath; Pu, pluvinus; Cm, culm.
