Locus name Alias Hormone Mutated site Paper description
AT2G02560 CULLIN-ASSOCIATED AND NEDDYLATION DISSOCIATED, ETA2 auxin eta2-1 mutation causes a Gly/Asp missense mutation at position 1069 of the ETA2 protein conserved in all of the predicted CAND1 homologs Arabidopsis ortholog of human Cullin Associated and Neddylation-Dissociated (CAND1)/TIP120A, a protein recently identified as a cullin-interacting factor
