Patent number: 7803927Abstract: Methods and compositions for the expression of transgenes in monocot plants including maize are disclosed. In the invention, gene silencing is avoided by use of monocot-homeologous sequences from plants of the genus Coix for transformation. Included in these transgene sequences are Coix promoters, enhancers, coding sequences and terminators. Suitable alternatives to maize-derived transgenes are desirable for expression in maize in that homology-based gene silencing can limit or effectively eliminate transgene expression.Type: GrantFiled: August 14, 2007Date of Patent: September 28, 2010Assignee: Monsanto Technology LLCInventors: Alan L. Kriz, Michael H. Luethy, Dale A. Voyles

Patent number: 6433252Abstract: The present invention provides methods and compositions for the identification of transgenic seeds. This is accomplished by use of screenable markers linked to aleurone-specific promoters. The screenable markers can be provided as gene fusions with selectable markers, allowing both selection and screening of transformants. The use of aleurone-specific promoters, which also direct expression in embryogenic tissues, allows efficient selection of transgenic cells and the screening of viable transgenic seeds, while avoiding the deleterious effects associated with constitutive expression of screenable marker genes. Screening of transgenic seeds avoids the need for growing and assaying of seeds for transgenes and allows implementation of automated seed screening techniques for the identification of transgenic seeds.Type: GrantFiled: October 24, 2000Date of Patent: August 13, 2002Assignee: Dekalb Genetics CorporationInventors: Alan L.
