Tobacco plants harboring qpt2 knockout mutations display a severe growth phenotype when grown in a field environment. A Control and mutant lines T8 and T21 in the TN90 background; B Controls and mutant line K19 in the K326 background. Tester and control lines were randomized within rows. Red arrows point to plants homozygous for qpt2 mutations; full-sized plants correspond to control and other entries. Picture was taken 32 days after transplant
