The Reproductive Development Phenotype of the cki1-8 Mutant.
(A) Left: Ten-week-old plants of the wild type, cki1-8, and cki1-8 carrying a CKI1:CKI1 transgene (Comp) germinated and grown under continuous white light. Note that cki1-8 continues to produce flowers (indicated by an arrow). Bar = 10 cm. Right: Quantitative analysis of the height of 10-week-old plants (n = 8). Standard deviations are indicated by bars. Asterisk indicates statistically significant differences compared with wild-type plants (Student's t test, P < 0.01).
(B) Inflorescences derived from 8-week-old (wild type) or 10-week-old (cki1-8) plants. Bar = 2 mm.
(C) Siliques (from left to right) of the wild type, CKI1/cki1-8, cki1-8, and cki1-8 carrying a CKI1:CKI1 transgene. Bar = 5 mm.
(D) Seed development in siliques. From left to right: wild type, CKI1/cki1-8 (red arrows show abortive ovules), cki1-8 (a rarely set seed indicated by a black arrow), and cki1-8 carrying a CKI1:CKI1 transgene. Bar = 1 mm.
(E) Increased seed weight in cki1-8. Average weight (μg/seed; at least 500 seeds were analyzed in each genotype) and standard deviations are given below the image. Bar = 1 mm.
