Flower phenotypes of ARP7Ri plants. A, Inflorescences of wild-type and strong (7Ri-S), moderate (7Ri-M), and normal (7Ri-N) group of ARP7Ri plant lines. WT, wild type. B to D, Flowers of wild-type (B) and strong ARP7Ri (C and D) lines. E, Sepals (bottom) and petals (top) of wild-type and strong (S) and moderate (M) ARP7Ri lines. F, Stamens from wild-type and strong and moderate ARP7Ri lines at the time of anthesis. G to J, Mature anthers from just-opened flowers of wild-type (G), strong (H and I), and moderate (J) ARP7Ri lines. K, Pistils of wild-type, strong (S), and moderate (M) RNAi lines at the time of anthesis. L, Mature green siliques of wild-type and ARP7Ri plants. Each silique represents an independent RNAi line. Scale bars = 10 mm (A); 1 mm (B–E, K); 0.5 mm (F); 0.1 mm (G–J); and 5 mm (L).
