Figure 4

Abnormal root curling and apical hook formation of dig5 mutants. (A) Root curling of Col-gl1, rcn1, and dig5 seedlings in the absence or presence of 5 µM NPA. (B) Hypocotyl elongation of Col-gl1 and dig5 in the absence or presence of 1.0 µM NPA. (C) Hypocotyl length of seedlings in (B). Data are means and standard deviation from 18 seedlings. (D) Apical hook formation of seedlings under the control, ACC (10 µM), and ACC (10 µM) + NPA (1 µM) treatments. Seedlings were germinated and grown in darkness for 3 days before taking the pictures.
