Mutational loss of the prohibitin AtPHB3 results in an extreme constitutive ethylene response phenotype coupled with partial loss of ethylene-inducible gene expression in Arabidopsis seedlings.

Abstract excerpt

The eer3-1 loss-of-function mutant, which was identified by screening for Arabidopsis mutant seedlings with an enhanced ethylene response, has both increased sensitivity and profound exaggeration of response to ethylene when visually assessed, yet exhibits partial ethylene insensitivity at the molecular level. The eer3-1 mutation represents a conditional allele with an ethylene-dependent phenotype that results...
