The genes for green fluorescent protein (GFP) and soybean glutamine synthetase (GS) were inserted between the genes for P1 and HC-Pro on pClYVV to create three recombinant plasmids: pClYVV-GFP, pClYVV-GFP-GS, and pClYVV-GFP:GS.
The plants expressing GS together with GFP became tolerant to the herbicide glufosinate, and flowered early.
