Figure 4 Genetic interactions are seen when mutations inGET3B are combined with mutations affecting ALB4 and/orSTIC2
Plants were grown in 12-h light/12-h dark conditions for 4 weeks. Top row: Images of (A) stic2 , (B) alb4 (C) srp54, (D) Columbia wild-type plants . Middle row: Phenotypes when get3b mutations were introduced:(E) stic2 get3b , (F) alb4 get3b ,(G) srp54 get3b , (H) get3b plants. Bottom row: (I) alb4 stic2, (J) alb4 stic2 get3b , (K) alb4 srp54 , (L) alb4 srp54 get3b plants. Black areas were added so that plants would be shown at equal magnification. Bars= 1 cm. (M) Rosette diameters of plants with different genotypes in the absence (left) or presence (right) of srp54 mutations. Data are presented as means + SE (n= 2-10 individual plants). Asterisks designate significant differences (Student’s t test, *P <0.05, **P <0.01) from wild-type or between the samples indicated with brackets.
