Es porque los científicos han creado 150 proteínas útiles de plantas de tabaco y una vacuna que mostró el potencial para el tratamiento de cáncer.Otros investigadores desarrollan una vacuna de las patatas que combate varias enfermedades que causan diarrea. Las patatas también son usadas en pruebas de laboratorio de una vacuna de cólera.Y algunos investigadores americanos quieren desarrollar vacunas de plátanos y tomates porque ellos son comidos la materia prima y parecen más prometedores para el consumo humano.
No everythying está tan bien en la biotecnología agrícola. Algunos investigadores temen que las cosechas de transgenic un día puedan conducir a insectos resistentes o que ellos pueden disminuir la diversidad de cosechas plantadas.Biotech empresas están preocupados sobre algunas campañas ambientales contra bioengineered foods.another la preocupación(el interés) es relacionada con una de las empresas biotech más importantes, en diciembre, los rumores difundieron esto esto había insertado un gene "de terminador" en su algodón transgenic. Este gene hace semillas estériles, entonces los agricultores tienen que comprar semillas cada estación de plantación.

Bioengineered crops may someday grow everything from modified foods to chemicals, biodegradable plastic an vaccines.
In fact, some modified plants already show potential for controlling some animal and human diseases.
In fact, some modified plants already show potential for controlling some animal and human diseases.
There is a vaccine to insume cattle against the bovine herpes virus.
It is derived from canola plants. Canadian researchers are developing plant-produced vaccines to prevent respiratory diseases in livestock. Tobacco farmers may unexpectedly improve their economy. in the future, they may harvest biotech tobacco plants plants for pharmaceutical companies.
That is because scientists have created 150 useful proteins from tobacco plants and a vaccine that showed potential for cancer treatment.
Other researchers are developing a vaccine from potatoes that combats several diarrhoea-causing diseases.
Potatoes are also used in laboratory tests for a cholera vaccine.
And some American researchers want to develop vaccines from bananas and tomatoes because they are eaten raw and look more promising for human consumption.
Not everythying is so good in agricultural biotechnology. Some investigators fear that transgenic crops may someday lead to resistant insects or that they may decrease the diversity of crops planted.
Biotech companies are worried about some environmental campaigns against bioengineered foods.another concern is related to one of the most important biotech companies, in december, rumours circulated that it had inserted a "terminator" gene in its transgenic cotton.
This gene makes seeds sterile, so farmers have to buy seeds every planting season.
