Mutated genes

Locus name Alias Hormone Mutated site Paper description
AT5G19180 E1-CONJUGATING ENZYME RELATED1(ECR1) auxin The missense mutation causes a leucine to phenylalanine change two amino acids away from the catalytic cysteine to which activated RUB is linked ubiquitin-like activating enzyme, forming heterodimer with AXR1
