Publication number: 20240110199Abstract: The present invention relates to methods and compositions for identifying, selecting and/or producing a pathogen resistant plant or germplasm (e.g., soybean plant or germplasm) using genes derived from Glycine tomentella. Candidate genes capable of conferring pathogen resistance (e.g., to Asian Soy Rust) are provided. A plant or germplasm that has been identified, selected and/or produced by any of the methods of the present invention is also provided.

Publication number: 20240060082Abstract: The present invention provides compositions, systems, and methods for conferring resistance to plant pathogens that express pathogen-specific proteases. Compositions of the invention may include a recombinant nucleic acid molecule comprising a promoter operably linked to a nucleotide sequence that encodes at least one substrate protein of a plant pathogen-specific protease expressed by a Phakopsora or Heterodera plant pathogen species. Additionally, the at least one substrate protein has a Phakopsora-specific or Heterodera-specific heterologous cleavage site, wherein cleavage of the cleavage site confers improved resistance to the Phakopsora or Heterodera plant pathogen species.Type: ApplicationFiled: January 14, 2022Publication date: February 22, 2024Applicant: Syngenta Crop Protection AGInventors: Qingli Liu, Clarence Michael Reynolds, Xiaoping Tan, Milan Jucovic

Publication number: 20230301255Abstract: Genes found in wild species can provide beneficial traits to domestic crops. For example, wild Glycine species can provide resistance to a broad spectrum of soy rust populations if introgressed into soybean. Previously, successful introgression required wide cross pollinations, embryo rescue, and regeneration of F1 shoots. Furthermore, chromosome doubling, which can be achieved by chemical treatment of embryos, was required in order to obtain fertile amphidiploids (F1Ds). A backcross to soybean was then required in order to obtain BC1F1 genetics. Here we describe improved procedures for interspecific crosses between soybean and Glycine tomentella. These procedures offer a more efficient route to BC1F1 genetics by bypassing the amphidiploid generation. These principles can be applied to additional domestic species and their wild relatives such as Brassica.Type: ApplicationFiled: August 4, 2021Publication date: September 28, 2023Applicant: Syngenta Crop Protection AGInventors: Qingli Liu, Craig Joseph Schuller, John Luther Dawson, Timothy Joseph Kelliher
