Publication number: 20220124998Abstract: The disclosure pertains to methods and compositions for the rapid and efficient transformation of plants. The disclosure further provides methods for producing a transgenic plant, comprising (a) transforming a cell of an explant with an expression construct comprising (i) a nucleotide sequence encoding a WUS/WOX homeobox polypeptide; (ii) a nucleotide sequence encoding a polypeptide comprising two AP2-DNA binding domains; or (iii) a combination of (i) and (ii); and (b) allowing expression of the polypeptide of (a) in each transformed cell to form a regenerable plant structure in the absence of exogenous cytokinin, wherein no callus is formed; and (c) germinating the regenerable plant structure to form the transgenic plant. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.Type: ApplicationFiled: January 7, 2022Publication date: April 28, 2022Applicant: PIONEER HI-BRED INTERNATIONAL, INC.Inventors: AJITH ANAND, MAREN L ARLING, ALEXANDRE DA SILVA CONCEICAO, WILLIAM JAMES GORDON-KAMM, CRAIG HASTINGS, GEORGE J HOERSTER, TODD J JONES, THEODORE M KLEIN, CARLOS M LA ROTA, KEITH S LOWE, SHIV BAHADUR TIWARI, NING WANG, XINLI EMILY WU

Patent number: 9163233Abstract: Compositions and methods for modulating expression of gene products are provided. Compositions comprise suppression cassettes that comprise a convergent promoter pair operably linked to a silencing element that, upon expression, is capable of decreasing the expression of one or more target polynucleotides of interest. Compositions of the invention also include transformed plants, plant cells, plant tissues, and plant seeds. Methods of transformation and regeneration of plants comprising the novel constructs are provided. The methods find use in regulating gene expression, particularly genes associated with agronomic traits of interest. Further provided are promoter sequences, cells, plants, and vectors comprising these promoter sequences and methods of their use.Type: GrantFiled: February 25, 2013Date of Patent: October 20, 2015Assignee: PIONEER HI-BRED INTERNATIONAL, INC.Inventors: Darren B.

Patent number: 7465852Abstract: Compositions and methods for the alteration of the disulfide status of plant proteins are provided. Novel nucleotide molecules, comprising nucleotide sequences for thioredoxin h and NADPH-thioredoxin reductase, and the proteins encoded thereby are provided. The nucleotide sequences can be used to transform plants alone or in combination with other sequences, such as sequences encoding NADPH generating enzymes, to manipulate the thioredoxin h system and alter the protein disulfide status in plants. Transformed plants, plant cells, plant tissues, seed and grain are provided.Type: GrantFiled: August 2, 2005Date of Patent: December 16, 2008Assignees: Pioneer Hi-Bred International, Inc., E.I. du Pont de Nemours and CompanyInventors: Vincent Sewalt, Craig Hastings, Robert Meeley, Sabine Susanne Hantke, Rudolf Jung, John D. Everard, Stephen M. Allen

Publication number: 20070089200Abstract: Compositions and methods for altering the levels of reversibly glycosylated polypeptide (RGP) in plants are provided. The present invention recognizes that by altering the level of expression of RGP, plants and seeds having beneficial qualities can be obtained. The invention involves controlled suppression of RGP expression to obtain plants and seeds having decreased amounts of hemicellulose and arabinose. Controlled suppression of RGP, particularly in vegetative tissues and seeds, leads to plants with desirable characteristics, including altered cell wall structure, reduced grain fiber content, increased seed protein, increased oil content, and altered arabinoxylan or xyloglucan levels. Compositions of the invention include constructs for the suppression of RGP and transformed plants and seeds having the altered phenotype of the invention.Type: ApplicationFiled: August 29, 2006Publication date: April 19, 2007Applicant: Pioneer Hi-Bred International, Inc.Inventors: Xiaoming Bao, Darren Gruis, Craig Hastings, George Singletary, Deborah Wetterberg
