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.

Transposable element-anchored, amplification method for isolation and identification of tagged genes
Patent number: 6881539Abstract: A method for the rapid isolation and identification of the DNA sequence of transposable element-tagged genes is provided. The method comprises a modified AFLP approach using a transposable element-anchored amplification to identify and clone an amplification product that is associated with a mutant phenotype. Once cloned, the amplification product of interest may be used to screen a cDNA library directly or may be sequenced and compared to available databases for sequence homology. A modification of this approach provides a method for the identification of the location of an additional type of insertion event into genomic DNA, more specifically transgene insertion into the genome of a host organism.Type: GrantFiled: February 16, 1999Date of Patent: April 19, 2005Assignee: Pioneer Hi-Bred International Inc.Inventors: John A.

Publication number: 20040221331Abstract: The present invention relates to an isolated nucleic acid sequence encoding the Ms45 male tissue-preferred regulatory region. In one aspect this invention relates the use of this male tissue-preferred regulatory region in mediating fertility. An example of such use is the production of hybrid seed such as in a male sterility system. The Ms45 male tissue-preferred regulatory region can be operably linked with exogenous genes, such as those encoding cytotoxins, complementary nucleotidic units and inhibitory molecules. This invention also relates to plant cells, plant tissue and differentiated plants which contain the regulatory region in this invention.Type: ApplicationFiled: November 14, 2003Publication date: November 4, 2004Inventors: Marc C.
