Mutated genes

Locus name Alias Hormone Mutated site Paper description
AT1G16540 ABA3/MCSU/LOS5/FRS1 abscisic acid In aba3-1/Col-0,a G-to-A change occurred at positin 3707 EMS. In aba3-2/Ler, a G-to-A change at position 3176, a T-to-A change at position 3178, and a deletion of T at position 3180. encodes Molybdenum cofactor sulfurase. Involved in Moco biosynthesis. Involved in the conversion of ABA-aldehyde to ABA, the last step of abscisic acid (ABA) biosynthesis.a single nuclear gene.
