    • Fine mapping and epistatic interactions of the vernalization gene VRN-D4 in hexaploid wheat 

      Kippes, Néstor Fabián; Zhu, Jie; Chen, Andrew; Vanzetti, Leonardo Sebastian; Lukaszewski, Adam; Nishida, Hidetaka; Kato, Kenji; Dvorak, Jan; Dubcovsky, Jorge (2014-02)
      Wheat vernalization requirement is mainly controlled by the VRN1, VRN2, VRN3, and VRN4 genes. The first three have been cloned and have homoeologs in all three genomes. VRN4 has been found only in the D genome (VRN-D4) and ...

    • Genetic structure of Argentinean hexaploid wheat germplasm 

      Vanzetti, Leonardo Sebastian; Yerkovich, Nadia; Chialvo, Eugenia; Lombardo, Lucio; Vaschetto, Luis; Helguera, Marcelo (2013-05)
      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 ...

    • Genomic relationships between hexaploid Helianthus resinosus and diploid Helianthus annuus (Asteraceae) 

      Miranda Zanetti, Julieta; Greizerstein, Eduardo Jose; Camadro, Elsa Lucila; Poverene, María Mónica; Echeverria, Mercedes; Poggio, Lidia; Carrera, Alicia Delia (Springer, 2014-05)
      Genus Helianthus comprises diploid and polyploid species. An autoallopolyploid origin has been proposed for hexaploid species but the genomic relationships remain unclear. Mitotic and meiotic studies in annual Helianthus ...

    • Identification and validation of QTL for spike fertile floret and fruiting efficiencies in hexaploid wheat (Triticum aestivum L.) 

      Pretini, Nicole; Vanzetti, Leonardo Sebastian; Terrile, Ignacio Ismael; Börner, Andreas; Plieske, Jörg; Ganal, Martin; Röder, Marion; Gonzalez, Fernanda Gabriela (Springer, 2020-06)
      The spike fruiting efficiency (FE—grains per unit spike dry weight at anthesis, GN/SDW) is a promising trait to improve wheat yield potential. It depends on fertile floret efficiency (fertile florets per unit SDW—FFE, ...
