Publication number: 20100186122Abstract: Auxotrophic Agrobacterium and methods employing auxotrophic Agrobacterium are provided. Auxotrophic Agrobacterium may be used in a variety of methods including biologically containing Agrobacterium comprising a transgene and transforming a plant cell without using an Agrobacterium counter-selective agent. Transforming maize immature embryos using an Agrobacterium auxotrophic for thymidine results in comparable transformation efficiency as transformation achieved using prototrophic Agrobacterium. Methods for producing an Agrobacterium thymidine auxotroph and using the auxotroph in transformation methods are disclosed. Transformed tissues and plants produced using methods of the present invention are also provided.Type: ApplicationFiled: December 30, 2009Publication date: July 22, 2010Applicant: PIONEER HI-BRED INTERNATIONAL, INC.Inventors: JEROME P. RANCH, MATTHIAS LIEBERGESELL, CARL W. GARNAAT, GARY A. HUFFMAN

Patent number: 7759544Abstract: Nucleotide sequences mediating male fertility in plants are described, with DNA molecule and amino acid sequences set forth. Promoter sequences and their essential regions are also identified. The nucleotide sequences are useful in mediating male fertility in plants. In one such method, the homozygous recessive condition of male sterility causing alleles is maintained after crossing with a second plant, where the second plant contains a restoring transgene construct having a nucleotide sequence which reverses the homozygous condition. The restoring sequence is linked with a hemizygous sequence encoding a product inhibiting formation or function of male gametes. The maintainer plant produces only viable male gametes which do not contain the restoring transgene construct. Increase of the maintainer plant is also provided by self-fertilization, and selection for seed or plants which contain the construct.Type: GrantFiled: September 22, 2009Date of Patent: July 20, 2010Assignee: Pioneer Hi-Bred International, IncInventors: Marc Albertsen, Tim Fox, Gary Huffman, Mary Trimnell, Youngzhon Wu, Howard Hershey

Publication number: 20060292815Abstract: A MIM capacitor is formed over one or more metal interconnect layers in a semiconductor device. The capacitor has a lower plate electrode and an upper plate electrode. An insulator is formed between the plate electrodes. Prior to forming the first plate electrode a first insulating layer is deposited over the metal of an interconnect layer. The first insulating layer is planarized using a chemical mechanical polish (CMP) process. A second insulating layer is then deposited over the planarized first insulating layer. The first plate electrode is formed over the second insulating layer. An insulator is formed over the first plate electrode and functions as the capacitor dielectric. A second plate electrode is formed over the insulator. Planarizing the first insulating layer and depositing a second insulating layer over the first insulating layer, reduces defects and produces a more reliable capacitor.Type: ApplicationFiled: June 28, 2005Publication date: December 28, 2006Inventors: Douglas Roberts, Gary Huffman

Patent number: 7154024Abstract: The present invention relates to isolated male tissue-preferred regulatory sequences from Ms45 gene. The invention also relates to the use of Ms45 gene male tissue-preferred regulatory sequences in mediating male fertility in a plant, and in producing hybrid seed. The Ms45 male tissue-preferred regulatory region can be operably linked to exogenous genes encoding cytotoxins or inhibitory molecules. The invention also relates to plant cells, plant tissue and plants that contain the MS45 gene regulatory sequences.Type: GrantFiled: November 14, 2003Date of Patent: December 26, 2006Assignee: Pioneer Hi-Bred, Inc.Inventors: Marc C.
