Detoxification or degradation of herbicide

Detoxification or degradation of herbicides is the basis of selective effect of herbicide, so that the latter wiIl kill the weeds and not the crop. A number of detoxifying enzymes have been identified in plants as well as in microbes.

Some of these enzymes include (i) glutathione-S transferase or GST (in maize and other plants), which detoxifies the herbicide atrazine; (ii) nitrilase (coded by gene bxn in Klebsiella pneumoniae), which detoxfies the herbicide bromoxynil, and

(iii) phosphinothricin acetyl transferase or PAT (coded by bar gene in Streptomyces spp.), which detoxifies the herbicide PPT (L-phosphinothricin).

Transgenic tomato plants using both bxn gene from Klebsiella and bar gene from Streptomyces, and transgenic plants in potato, oilseed rape (Brassica nap us) and sugarbeet using only bar gene from Streptomyces have been obtained and were found to be herbicide resistant.

Other target crops for engineered herbicide tolerance include soybean, cotton and corn. Herbicide resistant transgenic crops are already being commercially grown in large areas in several countries.
