(or pyramided genes)—Two or more gene systems inserted into the plant’s DNA that express similar (through enhanced) activity (e.g., two genes that encode for separate Bacillus thuringiensis endotoxin expression in the same plant, such as in Bollgard II or WideStrike), or two genes that express different activities in the same plant, such as Bollgard caterpillar resistance plus Roundup Ready glyphosate tolerance).
