  • Publication number: 20220142075
    Abstract: Compositions and methods useful in identifying and/or selecting maize plants that have anthracnose stalk rot resistance are provided herein. The resistance may be newly conferred or enhanced relative to a control plant. The methods use maize markers on chromosome 10 to identify, select and/or construct resistant plants. Maize plants generated by the methods also provided.

  • Publication number: 20220056470
    Abstract: The field is molecular biology, and more specifically, methods for chromosomal engineering of multiple native genes, such as disease resistance genes in a genomic locus using site-specific editing to produce plants. Also described herein are methods of generating heterologous genomic locus in a plant that comprises a plurality of intraspecies polynucleotide sequences.

  • Publication number: 20220030788
    Abstract: The field is molecular biology, and more specifically, methods for editing the genome of a plant cell to identify causal alleles of a desired trait or to fine map a desired trait to small region of the genome for gene identification.

  • Patent number: 10947602
    Abstract: Compositions and methods useful in identifying and selecting maize plants with increased resistance to gray leaf spot are provided herein. The methods use molecular genetic markers within a QTL region located on chromosome 4 to identify and select plants with increased resistance to gray leaf spot, and plants comprising the QTL allele associated with increased resistance to gray leaf spot can be crossed to other maize plants to incorporate the increased resistance into other maize lines or varieties.

  • Publication number: 20180112280
    Abstract: This invention relates to polynucleotide sequences encoding a gene that can confer resistance to the plant pathogen Colletotrichum, which causes anthracnose stalk rot, leaf blight and top dieback in corn and other cereals. It further relates to plants and seeds of plants carrying chimeric genes comprising said polynucleotide sequences, which enhance or confer resistance to the plant pathogen Colletotrichum, and processes of making said plants and seeds. The invention further presents sequences that can be used as molecular markers that in turn can be used to identify the region of interest in corn lines resulting from new crosses and to quickly and efficiently introgress the gene from corn lines carrying said gene into other corn lines that do not carry said gene, in order to make them resistant to Colletotrichum and resistant to stalk rot.
