fln1 fln2 double mutant analysis. F2 progeny from FLN1/fln1-1 FLN2/fln2-1 parents are shown. (A) and (B) F2 seeds were plated on GM and grown for three weeks with images taken at 1 week (A), 2 weeks, and 3 weeks (B). Pale and white seedlings were sacrificed for genotyping. Individuals identified as fln1 fln2 are circled. One individual accidentally moved on the plate during the growth period and is denoted with a star. (C) Left, middle and right sets of pictures, magnification of seedlings from the plate shown in (A), after 2 weeks growth, and from the plate in (B), respectively. Three representative seedlings are shown for each indicated genotype, with their phenotypes shown at different ages.
