摘要:
The compositions and methods are provided that enhance the selection of transgenic plants having two T-DNA molecules integrated into a plant genome at different physical and genetic loci. The compositions are DNA constructs that comprise novel arrangements of T-DNA molecules containing genes of interest, positive selectable marker genes, and conditional lethal genes. The methods disclosed herein comprises transforming a plant cell to comprise the DNA constructs of the present invention, regenerating the plant cell into a plant and identifying independent transgene loci, where the selectable marker genes or transgenic elements can be segregated in the progeny.
