Fig. 2. Phenotypes of bop1 and bop1 bop2 mutants. (A) Ectopic leaf formed from the petiole of a bop1-5 mutant plant grown in short days. (B) 24-day-old Col-0 wild-type plant (left) and bop1-5 bop2-2 double mutant plant (right). (C) Growth and development of leaf 1 and 2 from Col-0 wild type (left) and bop1-5 bop2-2 (right) from day 7 to day 22 after germination. Scale bar: 1 cm. (D,E) Inflorescences of Col-0 wild type (D) and a bop1-5 bop2-2 double mutant (E). Arrowheads point to bracts subtending the flowers. (F,G) Flowers of Col-0 wild type (F) and a bop1-5 bop2-2 double mutant (G). Arrowheads point to stipules growing from the base of the bract. Inset in G is a magnification of the proximal part of the bract. Scale bars: 1 mm. (H) Phenotypes of plants grown in short days. From left to right: Col-0 wild type (2 months old), bop1-5 bop2-2 double mutant (2 months old) and bop1-5 bop2-2 double mutant (5 months old). (I-K) Floral organ abscission in wild type (I) and bop1-5 bop2-2 double mutant (J,K). While wild type abscise their flower organs at an early stage (I), bop1-5 bop2-2 double mutants never abscise their flower organs (J,K). Scale bars: 1 cm. (K) Dry silique from a bop1-5 bop2-2 double mutant plant after dehiscence of seeds. The large arrowhead indicates the dry floral organs that are still attached. The small arrowhead (b) points to a bract that is delayed in senescence compared with the sepals.
