a
Expressed as a percentage.
b
Wild-type SMT1 plants contained 179 μg/g fresh weight.
c
Mutant smt1-1 plants contained 223 μg/g fresh weight. The smt1-1 plants are morphologically different from the wild type, and these tissue differences may influence the total sterol content.
d
ND, not determined.
