2 A time-course analysis of RHD1 transcript levels in wild-type plants treated with the ethylene precursor 1-aminocyclopropane-1-carboxylic acid showed a root-specific downregulation of RHD1 expression by ethylene. ethylene NAD(P)-binding Rossmann-fold superfamily protein Arabidopsis thaliana
3 A time-course analysis of RHD1 transcript levels in wild-type plants treated with the ethylene precursor 1-aminocyclopropane-1-carboxylic acid showed a root-specific downregulation of RHD1 expression by ethylene. ethylene NAD(P)-binding Rossmann-fold superfamily protein Arabidopsis thaliana

6 This observation was corroborated by our finding of increased RHD1 transcript levels in roots of the ethylene-insensitive mutants etr1 and ein2. ethylene NAD(P)-binding Rossmann-fold superfamily protein Arabidopsis thaliana
7 We conclude that RHD1 is a likely target of root-specific negative regulation by ethylene and that loss of RHD1 function results in a heightened sensitivity of root tissues to both ethylene and auxin. ethylene NAD(P)-binding Rossmann-fold superfamily protein Arabidopsis thaliana
8 We conclude that RHD1 is a likely target of root-specific negative regulation by ethylene and that loss of RHD1 function results in a heightened sensitivity of root tissues to both ethylene and auxin. ethylene NAD(P)-binding Rossmann-fold superfamily protein Arabidopsis thaliana
