Mutated genes

Locus name Alias Hormone Mutated site Paper description
AT5G65800 ACS5/ACC5/ETO2/CIN5 ethylene 1-aminocyclopropane-1-carboxylate synthase 5 (EC (ACC synthase 5) (S-adenosyl-L-methionine methylthioadenosine-lyase 5) (Ethylene-overproduction protein 2);constitutive ethylene response;overproduce ethylene.AtACS5, a key enzyme of ethylene biosynthesis in etiolated seedling; loss-of-function mutation of AtACS5 (eto2-2) suppresses the phenotype of eto1
