Mechanisms of action of different herbicides and basis of achieving resistance against them transgenic plants

Active principle of herbicide	Inhibited pathway	Target product	Use	Basis of resistance
I. Amino acid biosynthesis inhibitors
I. Glyphosate (Roundup)	Aromatic amino acid biosynthesis	EPSPS	Broad spectrum	Overexpression of EPSPS gene; bacterial aroA gene
2. Sulphonylurea and Imidazolinones	Branched chain amino acids	ALS	Selected crops	Mutant ALS gene
3. Phosphinothricin (Basta)	Glutamine biosynthesis	GS	Broad spectrum	Gene amplification, bar gene : detoxification
II. Photosynthesis inhibitors
4. Atrazine (Lasso)	Photosystem II	QB (32kDa protein)	Selected crops	Mutant PsbA gene. GST gene: detoxification
5. Bromoxynil (Buctril)	Photosynthesis	―	Selected crops	bxn gene: detoxification
