Abstract
The current invention provides the maize A3 promoter and actin 2 intron. Compositions comprising these sequences are described, as well as transformation constructs derived therefrom. Further provided are methods for the expression of transgenes in plants comprising the use of these sequences. The methods of the invention include the direct creation of transgenic plants with the A3 promoter directly by genetic transformation, as well as by plant breeding methods. The sequences of the invention represent a valuable new tool for the creation of transgenic plants, preferably having one or more added beneficial characteristics.
Claims46
A seed of a fertile R0 transgenic plant stably transformed with a selected DNA comprising a maize A3 promoter, wherein said seed comprises said selected DNA.
A progeny plant of any generation of a fertile R0 transgenic plant stably transformed with a selected DNA comprising a maize A3 promoter, wherein said fertile R0 transgenic plant comprises said selected DNA.
A crossed fertile transgenic plant prepared according to the method comprising the steps of:
- (i) obtaining a fertile transgenic plant comprising a selected DNA comprising a maize A3 promoter;
- (ii) crossing said fertile transgenic plant with itself or with a second plant lacking said selected DNA to prepare a seed of a crossed fertile transgenic plant, wherein said seed comprises said selected DNA;
- and
- (iii) planting said seed to obtain a crossed fertile transgenic plant.
A method of plant breeding comprising the steps of:
- (i) obtaining a transgenic plant comprising a selected DNA comprising a maize A3 promoter;
- and
- (ii) crossing said transgenic plant with itself or a second plant.
