A “53” form of these hormones is a major product formed in the 13-hydroxylation pathway. Pro·hexa·dione inhibits the synthesis of these hormones by antagonizing a namesake 3-oxidase. Defects (15[1])in negative regulators of these hormones, such as La and Cry, induce the generation of “slender” (-5[1])constitutive response mutants. The synthesis of these hormones begins with the conversion of GGPP to ent-kaurene. (-5[1])These hormones induce aleurone (“al-YOO-rone”) cells to (15[1])release (*) alpha-amylase. These hormones (10[1])act against abscisic acid (10[3]-5[1])to (10[1])break (10[2]-5[1])seed dormancy (10[2])and promote (10[1])germination. (10[5]-5[1])These (-5[1])hormones, which are named (10[4])for a (10[1])fungus that causes (10[1]-5[1])foolish seedling disease (10[1])in rice (10[1])plants, (10[1])target the meristem to initiate internodal (10[1])growth. For 10 points, name these stem-elongating hormones (-5[2])abbreviated as GAs. (10[4]-5[1])■END■ (10[11]0[3])
