      Eucalyptus dunnii is one of the most important Eucalyptus species for short-fiber pulp production in regions where other species of the genus are affected by poor soil and climatic conditions. In this context, E. dunnii ...

    • Genome-wide association studies in sunflower : towards sclerotinia sclerotiorum and diaporthe/phomopsis resistance breeding 

      Filippi, Carla Valeria; Corro Molas, Andres Ezequiel; Dominguez, Matías; Colombo, Denis Nahuel; Heinz, Nicolás; Troglia, Carolina Beatriz; Maringolo, Carla Andrea; Quiroz, Facundo Jose; Alvarez, Daniel; Lia, Veronica Viviana; Paniego, Norma Beatriz (MDPI, 2022-12)
      Diseases caused by necrotrophic fungi, such as the cosmopolitan Sclerotinia sclerotiorum and the Diaporthe/Phomopsis complex, are among the most destructive diseases of sunflower worldwide. The lack of complete resistance ...

    • Genome-wide diversity in lowland and highland maize landraces from southern South America: population genetics insights to assist conservation 

      Dominguez, Pia Guadalupe; Gutierrez, Ángela Verónica; Fass, Monica Irinia; Filippi, Carla Valeria; Vera, Pablo; Puebla, Andrea; Defacio, Raquel Alicia; Paniego, Norma Beatriz; Lia, Veronica Viviana (BioRxiv, 2024-02)
      Maize (Zea mays ssp. mays L.) landraces are traditional American crops with high genetic variability that conform a source of original alleles for conventional maize breeding. Northern Argentina, one the southernmost regions ...

    • K-mer counting and curated libraries drive efficient annotation of repeats in plant genomes 

      Contreras-Moreira, Bruno; Filippi, Carla Valeria; Naamati, Guy; García Girón, Carlos; Allen, James E.; Flicek, Paul (Wiley, 2021-09)
      The annotation of repetitive sequences within plant genomes can help in the interpretation of observed phenotypes. Moreover, repeat masking is required for tasks such as whole-genome alignment, promoter analysis, or pangenome ...

    • Main and epistatic QTL analyses for Sclerotinia Head Rot resistance in sunflower 

      Zubrzycki, Jeremias Enrique; Maringolo, Carla Andrea; Filippi, Carla Valeria; Quiroz, Facundo Jose; Nishinakamasu, Veronica; Puebla, Andrea Fabiana; Di Rienzo, Julio Alejandro; Escande, Alberto; Lia, Veronica Viviana; Heinz, Ruth Amelia; Hopp, Horacio Esteban; Cervigni, Gerardo Domingo Lucio; Paniego, Norma Beatriz (PLOS, 2017-12)
      Sclerotinia Head Rot (SHR), a disease caused by Sclerotinia sclerotiorum, is one of the most limiting factors in sunflower production. In this study, we identified genomic loci associated with resistance to SHR to support ...

    • Optimizing ddRADseq in non-model species: a case study in Eucalyptus dunnii maiden 

      Aguirre, Natalia Cristina; Filippi, Carla Valeria; Zaina, Giusi; Rivas, Juan Gabriel; Acuña, Cintia Vanesa; Villalba, Pamela Victoria; Garcia, Martin Nahuel; Gonzalez, Sergio; Rivarola, Maximo Lisandro; Martinez, Maria Carolina; Puebla, Andrea Fabiana; Morgante, Michele; Hopp, Horacio Esteban; Paniego, Norma Beatriz; Marcucci Poltri, Susana Noemi (MDPI, 2019-08)
      Restriction site-associated DNA sequencing (RADseq) and its derived protocols, such as double digest RADseq (ddRADseq), offer a flexible and highly cost-effective strategy for efficient plant genome sampling. This has ...

    • Phenotyping sunflower genetic resources for Sclerotinia head rot response: assessing variability for disease resistance breeding
