Abstract: Plant development can be altered by transforming a plant with a genetic construct that includes regulatory elements and DNA sequences capable of acting in a fashion to inhibit pollen formation or function, thus rendering the transformed plant reversibly male-sterile. In particular, the present invention relates to the use of dominant negative genes and an anther-specific promoter. Male sterility is reversed by incorporation into a plant of a second genetic construct which represses the dominant negative gene. The invention also relates to novel DNA sequences which exhibit the ability to serve as anther-specific promoters in plants.

Abstract: A family of genes has been found in plants, said genes encoding a family of developmental proteins that have homologous structures to the mammalian QM genes. Recombinant molecules which include the QM genes in plants are useful to transform cells and regenerate plants that, as a result, have altered developmental pathways. Methods of producing male sterile plants use recombinant molecules containing either the QM sense genes or antesense genes with appropriate promoters.

Abstract: Plant development can be altered by transforming a plant with a genetic construct that includes regulatory elements and structural genes capable of acting in a cascading fashion to produce a reversible effect on a plant phenotype. A first genetic construct comprising (i) an operator that is capable of controlling expression of a dominant negative gene, (ii) a dominant negative gene that, when expressed in a plant disrupts pollen formation or function, (iii) a tissue specific promoter that regulates the expression of a gene encoding a DNA-binding protein which binds to the operator and activates transcription, and (iv) a gene encoding a DNA binding region and an activating domain, causes male sterility in a plant. In particular, the present invention relates to the use of a DAM-methylase gene as a dominant negative gene and an anther-specific promoter. Male sterility is reversed by incorporation into a plant of a second genetic construct which represses the dominant negative gene.

In particular, the present invention relates to the use of an anther-specific promoter, designated 5126, and its operable linkage to a dominant negative gene, more particularly an exogenous methylase gene or DAM methylase gene, to achieve male sterility.

Abstract: Plant development can be altered by transforming a plant with a genetic construct that includes regulatory elements and DNA sequences capable of acting in a fashion to inhibit pollen formation or function, thus rendering the transformed plant male-sterile. In particular, the present invention relates to an isolated DNA molecule comprising an anther-specific promoter, designated 5126, its operable linkage to a DNA sequence encoding a gene product and transgenic plants comprising said DNA. More particularly the gene product linked to promoter 5126 disrupts the function or formation of pollen.
