One of the advantages of the BT Cotton is that it does not have the actual bacterium Bacillus thuriengensis in it which is harmless to humans. The other advantage is that the BT Cotton successfully repels the boll weevil larvae.
pesticide Bt cotton, or Bacillus thuringiensis cotton, is used the same as any other cotton. The only difference is that it has a protein genetically added which is identical to that of B. thuringiensis bacteria which is toxic to many caterpillars, especially Lepidoptera species. Therefore it is an economically important "built-in" insecticide.
Bt cotton is very similar to any normal cotton plant grown all these years except for the insect-resistance trait conferred by Bt genes. These genes are derived from a commonly found soil bacterium called Bacillus thuringiensis. The Bt genes are incorporated into cotton plants by a process called TRANSFORMATION. Once the Bt genes stably integrate into cotton plant they produce Bt proteins, which kills larvae feeding on plant parts. Thus Bt plants give protection from insect pests and thereby increase yields of cotton fibre.
BT-plant means plant having BT-gene like BT-cotton. These are transgenic plants developed by genetic engineering.
Some of it is, particularly in the US. This is good because GM corn such as the Bt variety will have fewer bug parts in it.
vhb
Bt stands for bacillus thuringiensis, a common soil bacterium toxic to lepidopteran insects. When "Bt" is placed before a plant name, such as in "Bt Brinjal" (the brinjal is known in the US as eggplant), it means the plant has been genetically modified to produce a protein toxic to certain insects in the same way the bacteria does.The protein has not been shown to be harmful to humans but is controversial in other contexts.
explain common but differentiated responsibility
Bt cotton is an example of genetically modified organism.
Bt cotton
Use of genetically modified crops helps us to minimize the use of fertilizers and chemicals so that their harmful effects on environment can be reduced.For example- Bt cotton is produced by a bacterium called Bacillus thuringiensis (Bt for short). Bt toxin gene has been cloned from the bacteria and been expressed in plants to produced resistance to insects without the need for insecticides; in effect created a bio-pesticide. Examples are Bt cotton, Bt rice, tomato, potato, soybean.corn etc.
because it just is a disadvantage
