    • Characterization of the repetitive DNA landscape in wheat homeologous group 4 chromosomes 

      Garbus, Ingrid; Romero, José Rodolfo; Miroslav, Valarik; Vanzurova, Hana; Karafiatova, Miroslava; Caccamo, Mario; Dolezel, Jaroslav; Tranquilli, Gabriela; Helguera, Marcelo; Echenique, Carmen Viviana (2015)
      Background: The number and complexity of repetitive elements varies between species, being in general most represented in those with larger genomes. Combining the flow-sorted chromosome arms approach to genome analysis ...

      Nisi, María Mercedes; Lombardo, Lucio; Helguera, Marcelo; Gomez, Dionisio Tomas; Donaire, Guillermo Manuel; Mir, Leticia Raquel; Perez, G.T. (Estación Experimental Agropecuaria Bordenave, INTA, 2021-09)
      Uno de los objetivos de los programas de mejoramiento es la generación de variabilidad genética y el desarrollo de líneas con características de interés agronómico e industrial como puede ser su calidad panadera Es conocido ...

    • Genome-wide identification of MITE-derived microRNAs and their targets in bread wheat 

      Crescente, Juan Manuel; Zavallo, Diego; Del Vas, Mariana; Asurmendi, Sebastian; Helguera, Marcelo; Fernandez, Elmer; Vanzetti, Leonardo Sebastian (BioMed Central, 2022-02)
      Background: Plant miRNAs are a class of small non-coding RNAs that can repress gene expression at the post-transcriptional level by targeting RNA degradation or promoting translational repression. There is increasing ...

    • Global genomic analyses of wheat powdery mildew reveal association of pathogen spread with historical human migration and trade 

      Sotiropoulos, Alexandros G.; Arango-Isaza, Epifanía; Ban, Tomohiro; Barbieri, Chiara; Bourras, Salim; Cowger, Christina; Czembor, Paweł C.; Ben-David, Roi; Dinoor, Amos; Ellwood, Simon R.; Graf, Johannes; Hatta, Koichi; Helguera, Marcelo; Wicker, Thomas (Nature Research, 2022-07-26)
      The fungus Blumeria graminis f. sp. tritici causes wheat powdery mildew disease. Here, we study its spread and evolution by analyzing a global sample of 172 mildew genomes. Our analyses show that B.g. tritici emerged in ...
