Plasmid PV-GMHT4355 was used to generate predecessor of MON87708. PV-GMHT4355 contains two T-DNAs. The first T-DNA designated T-DNA I, contains the dmo expression cassette. The second T-DNA , designated T-DNA II, contains the cp4 epsps expression cassette that was used for early event selection, and was segregated away from TDNA I by conventional breeding (self-pollination).

MON87708 exclusively contains the dmo expression cassette providing tolerance to the herbicide dicamba (2-methoxy-3,6-dichlorobenzoic acid).
