Cotton event MON88701 was developed using Agrobacterium-mediated transformation of germinated seeds of the cotton cultivar "Coker 130". Two novel gene expression cassettes are present in MON88701.

• One contains the dmo gene which was isolated from soil bacteria, and encodes the enzyme dicamba mono-oxygenase (DMO), an enzyme that inactivates the herbicide dicamba.

• The other contains the bar gene that encodes phosphinothricin N-acetyltransferase (PAT),a protein conferring tolerance to herbicides containing glufosinate ammonium (phosphinothricin).

Comprehensive molecular analyses of MON88701 indicate there is a single insertion site comprised of one complete copy of the two gene expression cassettes. Plasmid backbone analysis shows no extraneous sequences derived from the plasmid were incorporated into the cotton genome. The introduced genetic elements are stably inherited from one generation to the next.
