Many of the compounds could cause significant reductions in pgCAR, this situation is exemplified by treatment with these ligands, Baicalin, Liquiritin, Indigotin
, Daidzein, Betaine and Matrine, which were shown to give activities 88, 75, 99, 75, 90 and 90%, respectively compared to no-ligand DMSO control.

These improvements will be commercialized through higher indigotin
yielding breeders seed stock, with a goal of reaching 26,000 acres of cropland in the Southeast U.S.
They are: Erythrosin included in the class of xanthene dyes; Blue indigotine included in the indigotin
class of dyes, Patent Blue V, Fast Green and Brilliant Blue in class of triphenylmethane dyes, Bordeaux Red, Ponceau 4R, Red 40, Azorubine, Tartrazine Yellow and Sunset Yellow, included in the class of azo dyes (POLONIO; PERES, 2009).
When the solution is now whisked to introduce air, indoxyl reacts with oxygen to form indigotin
, the blue pigment.
