Figure 2.
Gain-of-Function GA-Insensitive Arabidopsis rgl1 Mutant. This transgenic plant overexpresses a mutated rgl1 gene, rgl1Δ17, which encodes a protein that lacks the 17–amino acid DELLA domain. Such plants exhibit a severe dwarf phenotype with small, dark green rosette leaves, poorly developed trichomes, and male-sterile flowers that produced stunted pistils protruding from underdeveloped sepals, petals, and stamens. Bar = 1 mm. (Figure courtesy of Caren Chang.)
