canola_002: Experimental cross-pollination between transgenic herbicide-resistant canola and wild field mustard led to highly fertile, herbicide-resistant wild field mustard.

canola_003: Transgenes that have escaped from glyphosate-resistant canola can persist in the wild.

cotton_001: Bt cotton showed decreased ability to kill cotton bollworm larvae during flower development and flowering.

cotton_002: Bt cotton had altered protein metabolism and produced less insecticidal toxin in leaves when subjected to high temperatures during boll formation.

maize_001: Bt maize has higher lignin content.

maize_002: Atlantic salmon fed Bt corn had altered enzyme activity in liver and intestine as well as altered proportions and numbers of different white blood cells.

maize_003: Monarch butterfly larvae exposed to anthers from Bt maize ate less and gained less weight.

maize_004: Byproducts from Bt maize enter streams, and in feeding experiments affected stream insects.

maize_005: Bt maize varieties matured more slowly and had on average lower grain yield and higher grain moisture content than conventional varieties.

maize_006: Bt maize had changed lipid composition in stems; also, lipid composition in soil was altered, and soil respiration was reduced.

soybean_001: Herbicide-resistant soybean plants were shorter, with less chlorophyll, lower weight, and increased susceptibility to stem-splitting at high temperatures.

soybean_002: Diet containing glyphosate-resistant soybeans affected the nuclei of liver cells in mice.

soybean_003: Glyphosate-resistant soybeans exuded glyphosate, carbohydrates, and amino acids into the soil and affected the microorganism soil community.

herbicide-resistant crops in general: Increased planting of glyphosate-resistant crops and application of glyphosate causes increase in glyphosate-resistant weed species.
