    摘要: A set of nucleic acid probes useful for tracking Maize Dwarf Mosaic Virus Resistance (MDMV), a polygenic trait, is provided. Chromosome segments are identified enabling isolation of the genes governing this trait.A general method for identifying probes useful for tracking and introgressing polygenic traits into elite genomes and identifying chromosome segments governing the traits is also provided. This method involves the analysis of RFLP polymorphisms between parent donor and recipient genotypes and observed phenotypic data using multiple regression by leaps and bounds ("leaps"), followed by standard multiple regression applied to the "leaps" data. The "leaps" data may be used to identify flanking markers, and epistasis may be determined by analysis of the multiple regression data.Kits comprising a subset of the most useful probes (those most closely linked to the trait of interest) are provided. The kits may also comprise flanking probes. Flanking probes used in combination with the most closely linked probes are useful in identifying situations in which donor DNA tends to move in clumps and recovering rare individuals in which traits of interest have separated from surrounding donor DNA, so that elite recipient DNA may be maximized.

    摘要: A method for producing a transgenic plant includes providing a nucleic acid molecule comprising at least two regions of nucleic acid sequence that lack sequence homology with genomic DNA of the plant cell, and at least two zinc finger nuclease recognition sites, wherein the at least two regions of nucleic acid sequence that lack sequence homology with genomic DNA of the plant cell flank the at least two zinc finger nuclease recognition sites. A plant cell or tissue having the nucleic acid molecule stably integrated into the genome of the plant cell is transformed. A plant is regenerated from the plant cell. Transgenic plants are produced by the method. Seeds are produced by the transgenic plants.
