  • Publication number: 20120185966
    Abstract: This invention relates to isolated nucleic acid fragments encoding fructosyltransferases. More specifically, this invention relates to polynucleotides encoding 1-FFTs, 6-SFTs, or 1-SSTs. The invention also relates to the construction of a recombinant DNA constructs encoding all or a portion of the fructosyltransferases, in sense or antisense orientation, wherein expression of the recombinant DNA construct results in production of altered levels of the fructosyltransferases in a transformed host cell.

  • Publication number: 20120054921
    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.
