(A) Eight-day-old wild-type and ago1-33 siblings germinated and grown in the light in the presence or absence of 5 μM picloram.

(B) Wild-type and ago1-33 siblings (left) and sur2-3 and ago1-33 sur2-3 siblings (right). Seedlings were germinated and grown in the light for 8 d.

(C) and (D) Three-week-old ago1-3 (C) and wild-type (D) siblings grown in the light on media without or with increasing concentrations of 1-NAA. Arrows indicate the hypocotyl/root junction.

(E) Wild-type Col-0 (left) and sur1-3 (right) seedlings grown for 15 d in vitro.

(F) One-month-old sur1-3 ago1-3 double mutant.
