Some Examples of Rreported Nontarget Effects of Genetically Engineered Plants and Bacteria

Plant or bacteria engineered trait	Function normally intended	Unintentional effects
Cotton/B.t. Kurstaki	Controls lepidopteran pest	Temporary increase in soil bacteria and fungal numbers and also alterations in species composition of bacteria
Tobacco-protease inhibitor	Insecticidal tobacco model	Decreased the population of Collembola but increased the population of nematodes.
Tobacco-pathogenesis related proteins.	Disease resistant tobacco model	Decrease in the level of AM infection.

Plant or bacteria engineered trait	Function normally intended	Unintentional effects
Klebsiella planticola	Model biomass conversion agent for ethanol production	Temporary decrease in AM infection in wheat and phytotoxicity to wheat.
Pseudomonas fluorescens	Degrader of 2, 4-D herbicide	Decreased soil fungal numbers
Streptomyces lividans	Cellulose degrader	Temporary increase in CO2 evolution upon addition of lignocellulose.
Pseudomonas fluorescens	Biocontrol agent	Plasmid DNA transferred to several genera of indigenous bacteria.
Pseudomonas Sp. B13	3-Chlorobenzoate degradation	Transferred the gene for this character into Alcaligenes in a natural aquifer
