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.
