Patent number: 7638680Abstract: Methods are disclosed for detecting genetic instability for apomixis in angiospermous plant, and for enhancing, genetically stabilizing, and controlling apomixis expression in such plants. Enhanced expression, stabilization, and control are achieved by converting a facultative apomict to obligate apomixis. Enhanced expression of apomixis is further achieved by increasing frequencies of unreduced egg formation and/or parthenogenesis. Genetic stabilization of apomixis is alternatively achieved by conferring mechanisms to a facultative apomict that, during facultative sexual seed formation, prevent the segregational loss of unique alleles at multiple loci, which cause apomixis, such that progeny produced sexually from the facultative apomict inherit the unique allelic combinations required to maintain apomixis. The disclosed methods are used in various combinations to produce apomictic plants that possess improved yield, quality, and/or seed production characteristics.Type: GrantFiled: February 6, 2004Date of Patent: December 29, 2009Assignee: Utah State UniversityInventor: John G.

Publication number: 20090315634Abstract: In one exemplary embodiment, a transmission line geometry or structure may readily be realized as periodic printed coupled/uncoupled microstrip lines on dielectric and/or suitable biased ferromagnetic substrates. An example of a transmission line geometry or structure may be adapted to emulate extraordinary propagation modes within bulk periodic assemblies of anisotropic dielectric and magnetic materials. For instance, wave propagation in anisotropic media may be emulated by using a pair of coupled transmission lines (30, 32) having a specially designed geometry, thereby enabling mold wave dispersion in a microwave or optical guided wave structure.
