    • Association mapping in sunflower for sclerotinia head rot resistance 

      Fusari, Corina Mariana; Di Rienzo, Julio A.; Troglia, Carolina Beatriz; Nishinakamasu, Veronica; Moreno, Maria Valeria; Maringolo, Carla Andrea; Quiroz, Facundo Jose; Alvarez, Daniel; Escande, Alberto; Hopp, Horacio Esteban; Heinz, Ruth Amelia; Lia, Veronica Viviana; Paniego, Norma Beatriz (BMC, 2012-06)
      Background: Sclerotinia Head Rot (SHR) is one of the most damaging diseases of sunflower in Europe, Argentina, and USA, causing average yield reductions of 10 to 20 %, but leading to total production loss under favorable ...
    • Identification and characterization of contrasting sunflower genotypes to early leaf senescence process combining molecular and physiological studies (Helianthus annuus L.) 

      López Gialdi, A.I.; Moschen, Sebastian Nicolas; Villán, C.S.; López Fernández, María Paula; Maldonado, Sara Beatriz; Paniego, Norma Beatriz; Heinz, Ruth Amelia; Fernandez, Paula Del Carmen (2016)
      Leaf senescence is a complex mechanism ruled by multiple genetic and environmental variables that affect crop yields. It is the last stage in leaf development, is characterized by an active decline in photosynthetic rate, ...
    • Identification of candidate genes associated with leaf senescence in cultivated sunflower (Helianthus annuus L.) 

      Moschen, Sebastian; Bengoa Luoni, Sofia Ailin; Paniego, Norma Beatriz; Hopp, Horacio Esteban; Dosio, Guillermo Aníbal Adrián; Fernandez, Paula Del Carmen; Heinz, Ruth Amelia (PLOS, 2014)
      Cultivated sunflower (Helianthus annuus L.), an important source of edible vegetable oil, shows rapid onset of senescence, which limits production by reducing photosynthetic capacity under specific growing conditions. ...
    • Integration of transcriptomic and metabolic data reveals hub transcription factors involved in drought stress response in sunflower (Helianthus annuus L.) 

      Moschen, Sebastian Nicolas; Di Rienzo, Julio A.; Higgins, Janet; Tohge, Takayuki; Watanabe, Mutsumi; Gonzalez, Sergio Alberto; Rivarola, Maximo Lisandro; García-García, Francisco; Dopazo, Joaquín; Hopp, Horacio Esteban; Hoefgen, Rainer; Fernie, Alisdair R.; Paniego, Norma Beatriz; Fernandez, Paula Del Carmen; Heinz, Ruth Amelia (2017-07)
      Drought is one of the most important environmental stresses that effects crop productivity in many agricultural regions. Sunflower is tolerant to drought conditions but the mechanisms involved in this tolerance remain ...
    • 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 ...
    • Network and biosignature analysis for the integration of transcriptomic and metabolomic data to characterize leaf senescence process in sunflower 

      Moschen, Sebastian Nicolas; Higgins, Janet; Di Rienzo, Julio A.; Heinz, Ruth Amelia; Paniego, Norma Beatriz; Fernandez, Paula Del Carmen (2016)
      In recent years, high throughput technologies have led to an increase of datasets from omics disciplines allowing the understanding of the complex regulatory networks associated with biological processes. Leaf senescence ...
    • Population structure and genetic diversity characterization of a sunflower association mapping population using SSR and SNP markers 

      Filippi, Carla Valeria; Aguirre, Natalia Cristina; Rivas, Juan Gabriel; Zubrzycki, Jeremias Enrique; Puebla, Andrea Fabiana; Cordes, Diego Darío; Moreno, Maria Valeria; Fusari, Corina Mariana; Alvarez, Daniel; Heinz, Ruth Amelia; Hopp, Horacio Esteban; Paniego, Norma Beatriz; Lia, Veronica Viviana (BMC, 2015-02)
      Background: Argentina has a long tradition of sunflower breeding, and its germplasm is a valuable genetic resource worldwide. However, knowledge of the genetic constitution and variability levels of the Argentinean germplasm ...
    • Sunflower germin-like protein HaGLP1 promotes ROS accumulation and enhances protection against fungal pathogens in transgenic Arabidopsis thaliana 

      Beracochea, Valeria Cecilia; Almasia, Natalia Ines; Peluffo, Lucila; Nahirñak, Vanesa; Hopp, Horacio Esteban; Paniego, Norma Beatriz; Heinz, Ruth Amelia; Vazquez Rovere, Cecilia; Lia, Veronica Viviana (Springer, 2015-10)
      Germin-like proteins (GLPs) are a large, diverse and ubiquitous family of plant glycoproteins belonging to the Cupin super family. These proteins have been widely studied because of their diverse roles in important plant ...
    • Sunflower: a potential fructan-bearing crop? 

      Martínez-Noël, Giselle M. A.; Dosio, Guillermo; Puebla, Andrea Fabiana; Insani, Ester Marina; Tognetti, Jorge (2015-10)
      Grain filling in sunflower (Helianthus annuus L.) mainly depends on actual photosynthesis, being the contribution of stored reserves in stems (sucrose, hexoses, and starch) rather low. Drought periods during grain filling ...
