  • Patent number: 8148506
    Abstract: Applicants have used protein design to develop novel functional protein architectures, termed protein kinase-inducible domains, whose structures are dependent on phosphorylation by specific protein kinases or are dependent on dephosphorylation by specific protein phosphatases. Applicants have designed kinase-inducible domains based on a modular architecture, which allows kinase-inducible domains to be responsive to any specific serine-threonine kinases. Kinase-inducible domains can consist of canonical amino acids, allowing their use as expressible tags of protein kinase activity.

  • Patent number: 8084671
    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.
