Mutated genes

Locus name Alias Hormone Mutated site Paper description
AT5G02310 PRT6 abscisic acid Encodes PROTEOLYSIS6 (PRT6), a component of the N-end rule pathway that targets protein degradation through the identity of the amino-terminal residue of specific protein substrates. Another component of the N-end rule pathway is arginyl-tRNA:protein arginyltransferase (ATE). Arabidopsis contains two ATE genes: At5g05700/ATE1, At3g11240/ATE2. PRT6 and ATE were shown to regulate seed after-ripening, seedling sugar sensitivity, seedling lipid breakdown, and abscisic acid (ABA) sensitivity of germination.
AT5G67030 ABA1/LOS6/ZEP abscisic acid encodea a Zeaxanthin epoxidase in first step of the biosynthesis of the abiotic stress hormone abscisic acid
