Development of sco1-1 embryos. Representative embryos were dissected from the middle of siliques on days 8 and 14 after anthesis. With respect to developmental rate and morphology, sco1-1 embryos were similar to wild type. The sco1-1 embryos were green from days 6 to 12, but appeared slightly paler compared to wild-type embryos of similar age. DAF = days old after fertilization.
