Fig. 1. Development of CAF-1 mutant seedlings. (A) Representative 9-day-old light-grown seedlings of CAF-1 mutants and their corresponding wild types. (B) After induction of germination by a 10-hour exposure to white light, seeds were kept in the dark at 23°C. Hypocotyl lengths of at least 20 seedlings were determined after 4 days and expressed relative to their corresponding wild types. Means±s.e.m. of at least three independent experiments are shown.
