FIGURE 2

Proposed involvement of GSTs in biosynthesis of indolic glucosinolates (A), camalexin (C), and other sulfur-containing phytoalexins (B). Dashed arrows represent multistage processes. Red color indicates glutathione and its fragments in structures of respective sulfur-containing metabolites. GSTs with function confirmed with mutant phenotype are indicated in blue. GSTs with contribution proposed based on co-expression analysis are indicated in green.
