Development of ape1L-1, ape2-1 embryos in siliques at different stages of development1.

1Siliques were taken from self-fertilized ape1L-l+/−, ape2-1−/− plants.2Silique stage was scored based on the stage of development of the largest class of embryos in the seeds of the silique.3Numbers indicate the proportion (%) of embryos of each stage found in mutant siliques; numbers in parentheses indicate the proportion (%) of seeds found in wild-type siliques at the same stage of development.
