Abstract excerpt
Several Arabidopsis mutants of the ecotype Dijon were isolated that show resistance to the herbicide acifluorfen, which inactivates protoporphyrinogen oxidase (PPOX), an enzyme of tetrapyrrole biosynthesis. This enzyme provides protoporphyrin for both Mg chelatase and ferrochelatase at the branchpoint, which leads to chlorophyll and heme, respectively. One of the mutations, aci5-3, displays semidominant...
