Abstract excerpt

RGA (repressor of ga1-3) and GAI (gibberellin insensitive) are negative regulators of plant hormone gibberellin (GA) signaling in Arabidopsis. The GA-deficient mutant ga1-3 is a nongerminating, extreme dwarf that flowers late and produces male-sterile flowers. The rga and gai null alleles interact synergistically to rescue vegetative growth and floral initiation in ga1-3, indicating that RGA and GAI are major...
