Methods and compositions for expression of transgenes in plants
View Patent ↗The invention provides isolated gamma coixin promoters useful for the expression of heterologous coding sequences in transgenic plants. Further provided by the invention are transgenic plants comprising such promoters, expression constructs for the introduction of heterologous coding sequences into plants, and methods of using the plants and nucleic acids provided by the invention.
1. An isolated gamma coixin promoter, wherein the promoter comprises the nucleic acid sequence af SEQ ID NO:8 or a fragment comprising at least about 80 nucleotides thereof having promoter activity.
2. The isolated gamma coixin promoter of claim 1 , further defined as operably linked to an exogenous gene.
3. The isolated gamma coixin promoter of claim 2 , wherein the exogenous gene is operably linked to a tenninator.
4. A fertile transgenic plain transformed with the isolated gamma coixin promoter of claim 1 .
5. The fertile transgenic plant of claim 4 , further defined as a progeny plant of any generation of a plant comprising said isolated gamma coixin promoter.
6. The fertile transgenic plant of claim 4 , wherein the plant was regenerated from a cell transformed with said isolated gamma coixin promoter.
7. An expression vector comprising the isolated gamma coixin promoter of claim 1 .
