Zygotic Lethality in the hog1-4 and met1-7 Mutants.
(A) Wild-type (HOG1) silique.
(B) Silique from a hemizygous hog1-4/HOG1 plant. Note the presence of aborted hog1-4 homozygote seeds.
(C) Silique from a plant hemizygous for both hog1-4 and the complementing SAH hydrolase T-DNA. Note the decrease in zygotic lethality.
(D) Silique from a hemizygous met1-7/MET1 plant. Note the presence of aborted met1-7 homozygote seeds.
