Protein Variants

Protein Variants Comment Organism
additional information plants homozygous for a null allele in AAO4 show a reduction of 30% to 45% in the total levels of benzoic acid in seeds as well as 7% to 9% and 32% to 38% decreases in the levels of 3-benzoyloxypropylglucosinolate and 4-benzoyloxybutylglucosinolate, respectively Arabidopsis thaliana
