Promoters


Promoters from non-plant sources express poorly in plants (except promoters of T-DNA) and promoters of non-animal sources express poorly in animl11s. Therefore, to obtain correct expression, genes transferred to plants should be linked to plant-specific promoters and those transferred to animals should be linked to animal-specific promoters.

These promoters can also be interchanged so as to confer on the transferred gene, a specific pattern of expression (tissue specific or stimulus specific or development stage specific expression). To illustrate this, some examples of promoters used in plants and insects will be discussed.
