摘要： Trap and/or refuge crops and methods of use in managing corn rootworm and other insect pests of maize are provided. Some methods involve using trap crops comprising plants with enhanced susceptibility to one or more insect pests to lure and kill insect pests. Other methods involve using refuge crops comprising plants with enhanced susceptibility to one or more insect pests to monitor insect pest populations in an area or to promote mating between insecticide resistant and insecticide non-resistant insects.

摘要： Methods and compositions for increasing a plant's resistance to an insect pest such as the corn rootworm are provided. Methods are provided for overexpression of Crw1, or variants thereof, in a host plant or plant cell to increase resistance to an insect pest in a plant such as maize. Moreover, methods are provided for identifying variants of Crw1 that when incorporated into a plant via transgenic or traditional breeding means increase resistance to an insect pest in a plant such as maize.

摘要： Methods and compositions for increasing a plant's resistance to an insect pest such as the corn rootworm are provided. Methods are provided for overexpression of Crw2, or variants thereof, in a host plant or plant cell to increase resistance to an insect pest in a plant such as maize. Methods are also provided for identifying variants of Crw2 that when incorporated into a plant via transgenic or traditional breeding means increase resistance to an insect pest in a plant such as maize. Also provided are methods for increasing resistance by overexpressing Crw1 and Crw2.

摘要： 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.

摘要： Isolated polynucleotides and polypeptides and recombinant DNA constructs useful for enhancing mechanical stalk strength in plants, compositions (such as plants or seeds) comprising these recombinant DNA constructs, and methods utilizing these recombinant DNA constructs. The recombinant DNA construct comprises a polynucleotide operably linked to a promoter that is functional in a plant, wherein said polynucleotide encodes a CTL1 polypeptide.
