Quantitative trait loci for Fusarium and Gibberella ear rot resistance in Argentinian maize germplasm
Giomi, Gerardo Mario; Iglesias, Juliana; Kreff, Enrique D.; Fauguel, Carolina Maria; Fernández, Mariana; Oviedo, María Silvina; Presello, Daniel Alberto (2016)Fusarium verticillioides and F. graminearum cause ear rots in maize (Zea mays L.) that reduce yield and contaminate the grain with mycotoxins produced by the fungi. To map QTLs for resistance to these ear rots, a F5 mapping ... -
Relative performance of cluster algorithms and validation indices in maize genome-wide structure patterns
Videla, María Eugenia; Iglesias, Juliana; Bruno, Cecilia Inés (Springer Nature, 2021-09)A number of clustering algorithms are available to depict population genetic structure (PGS) with genomic data; however, there is no consensus on which methods are the best performing ones. We conducted a simulation study ... -
Respuesta hormonal del maíz (Zea mays L.) durante la interacción con el patógeno Xanthomonas vasicola pv. vasculorum
Del Dago, Daiana Alejandra Aye; Vélez, Pilar Andrea; Theumer, Martín Gustavo; Iglesias, Juliana (2023-09)La interacción entre el maíz (Zea mays L.) y Xanthomonas vasicola pv. vasculorum (Xvv), causante del rayado foliar bacteriano emergente en Argentina, ha sido poco explorada. Las hormonas juegan un rol crucial en la defensa ... -
Severity of Fusarium ear rot and concentration of fumonisin in grain of Argentinian maize hybrids
Presello, Daniel Alberto; Iglesias, Juliana; Botta, Grisela; Eyherabide, Guillermo (Elsevier, 2007-06)Fusarium ear rot severity and fumonisin concentration in grain of 16 Argentinian maize hybrids were assessed after inoculation with Fusarium verticillioides. Differences among hybrids for both traits indicate that field ... -
Unravelling the complexity of maize resistance to bacterial and fungal diseases: an integrative perspective
Kistner, María Belén; Romero, Ana María; Iglesias, Juliana (Springer Nature, 2022-02)Maize is one of the most important cereals for both human and animal nutrition, and diseases that affect the crop pose a major threat to global food security. Breeders are racing against time to develop genotypes resistant ... -
Volatile compounds released by maize grains and silks in response to infection by Fusarium verticillioides and its association with pathogen resistance
Fauguel, Carolina Maria; Campos Bermudez, Valeria Alina; Iglesias, Juliana; Fernandez, Mariana; Farroni, Abel Eduardo; Andreo, Carlos Santiago; Presello, Daniel Alberto (2016)Many plants respond to fungal infections by producing and/or emitting a specific blend of oxylipins, some of them through the lipoxygenase (LOX) pathway. In vitro bioassays revealed that volatiles from silks and grains of ...
