They are resistant to bacterial and viral diseases (e.g. tomato, potato, etc), insect pests (Bt cotton), herbicides (e.g. maize and wheat) and abiotic stresses.
Transgenic plants can be used as bioreactors or factories (molecular farming) for production of novel drugs like interferons, humanized antibodies against infective agents like HIV, amino acids and immunotherapeutic drugs.
Some transgenic plants have improved nutritional qualities, e.g. golden rice and golden mustard are biofortified with vitamin A.
Transgenic plants like Flavr savr tomatoes have been engineered to have more shelf life.
