<i>ETR1</i>-Specific Mutations Distinguish ETR1 from Other Arabidopsis Ethylene Receptors as Revealed by Genetic Interaction with<i>RTE1</i>

Abstract

The plant growth regulator ethylene is perceived by a family of homologous receptors that negatively regulate ethylene responses. It is well established that dominant missense mutations within the ethylene-binding domain of any of these receptors result in ethylene insensitivity ([Chang et al., 1993
