The sd-1 "green revolution" rice mutant has a defect in the production of these hormones.
The sd-1 "green revolution" rice mutant has a defect in the production of these hormones. The synthesis of these compounds requires the cyclization of geranylgeranyl disphosphate to kaurene. These hormones facilitate the action of PIFs during the etiolation response by triggering the degradation of DELLA proteins. They were originally discovered due to fungal infections in rice causing chlorosis, a condition called (*) foolish seedling disease or bakanae. These hormones trigger the synthesis of amylase in the aleurone layer when water is available, antagonizing the function of abciscic acid. Spraying one of these hormones on grapes causes them to become seedless. For 10 points, name these plant hormones responsible for seed germination.
