Genetic Mapping of an Aegilops tauschii–derived Hessian Fly Resistance Gene in Common Wheat
Hessian fl y [Mayetiola destructor (Say)] is a major threat to wheat (Triticum aestivum L.) production in the eastern United States. Cultivar releases containing major Hessian fl y resistance genes have proven effective in minimizing losses caused by this pest. Nevertheless, the ephemeral nature of major gene resistance necessitates the identifi cation of novel sources of resistance. Hessian fl...
متن کاملInduced epidermal permeability modulates resistance and susceptibility of wheat seedlings to herbivory by Hessian fly larvae
Salivary secretions of neonate Hessian fly larvae initiate a two-way exchange of molecules with their wheat host. Changes in properties of the leaf surface allow larval effectors to enter the plant where they trigger plant processes leading to resistance and delivery of defence molecules, or susceptibility and delivery of nutrients. To increase understanding of the host plant's response, the ti...
متن کاملGenetic structure of Argentinean hexaploid wheat germplasm
The identification of genetically homogeneous groups of individuals is an ancient issue in population genetics and in the case of crops like wheat, it can be valuable information for breeding programs, genetic mapping and germplasm resources. In this work we determined the genetic structure of a set of 102 Argentinean bread wheat (Triticum aestivum L.) elite cultivars using 38 biochemical and m...
متن کاملChromosomal Location of Genetic Male Sterility Genes in Four Mutants of Hexaploid Wheat
of the 4BS chromosome arm (Endo et al., 1991). The dominant male-sterile genes Ms2 and Ms3 are located Few genetic male sterility (GMS) genes have been mapped in in chromosome arms 4DS and 5AS, respectively (Mchexaploid wheat (Triticum aestivum L.). Our objective was to locate to chromosomes the GMS genes in mutants FS2, FS3, FS20, and FS24. Intosh et al., 1998). The Ms4 gene is a dominant male...
متن کاملChromosomal location of genes controlling flavonoid production in hexaploid wheat.
Two-dimensional paper chromatography was performed on methanol extracts of leaves of hexaploid bread wheat, Triticum aestivum L. em. Thell. cultivar Chinese Spring, and of the available nullisomic-tetrasomic compensating lines, the tetrasomic lines and the ditelocentric lines. The chromatograms had 27 spots identified as flavonoids and six representing phenolic acids. Some of the areas were com...
