An isopentenyl transferase transgenic wheat isoline exhibits less seminal root growth impairment and a differential metabolite profile under Cd stress
(Wiley, 2021-09)Cadmium is one of the most important contaminants and it induces severe plant growth restriction. In this study, we analyzed the metabolic changes associated with root growth restriction caused by cadmium in the early ... -
Characterization and use in wheat breeding of leaf rust resistance genes from durable varieties
(MDPI, 2021-11)Leaf rust is one of the most significant diseases of wheat worldwide. In Argentina, it is one of the main reasons for variety replacement that becomes susceptible after large-scale use. Some varieties showed durable ... -
Characterization of Fusarium graminearum isolates recovered from wheat samples from Argentina by Fourier transform infrared spectroscopy : phenotypic diversity and detection of specific markers of aggressiveness
(2017-03)Fusarium graminearum is the primary causal agent of Fusarium head blight of wheat in Argentina. This disease affects crop yields and grain quality also reducing the wheat end-use, and causing mycotoxin contamination. The ... -
Estudios biológicos en pulgones (Hemiptera, Aphididae) plaga del trigo (Triticum aestivum L., Poaceae) para el desarrollo de métodos de control de bajo impacto ambiental
(Facultad de Ciencias Exactas y Naturales, Universidad de Buenos Aires, 2021-03)Los áfidos causan importantes pérdidas económicas en el cultivo de trigo. Los distintos genotipos de plantas manifiestan distintos niveles de resistencia contra las plagas. Para contar con información aplicable a medidas ... -
Evaluación de tres clases de trigo para la cría de Sitotroga cerealella (Lepidoptera: Gelechiidae) como hospedante utilizado en la cría de enemigos naturales
(Sociedad Entomológica Argentina, 2016)La estandarización de protocolos para la cría artificial es esencial para lograr una producción de insectos adecuada en calidad y cantidad. Los huevos de Sitotroga cerealella Olivier se utilizan para la cría de parasitoides ... -
Fine mapping of LrSV2, a race-specific adult plant leaf rust resistance gene on wheat chromosome 3BS
(Springer, 2014-05)Three leaf rust resistance genes were identified in the durable leaf rust resistant Argentinean wheat variety Sinvalocho MA: the seedling resistance gene Lr3 on distal 6BL and two adult plant resistance genes, LrSV1 and ... -
Genome-wide identification of MITE-derived microRNAs and their targets in bread wheat
(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 ... -
Induced mutations in crop plants : mutants of scientific and/or agronomic interest at the Institute of Genetics “Ewald A. Favret” = Mutaciones inducidas en plantas cultivadas : mutantes de interés interés científico y/o agronómico en el Instituto de Genética “Ewald A. Favret”
(Universidad San Francisco de Quito, 2021-05)The use of induced mutations techniques in crop plants at Instituto de Genética "Ewald A. Favret" (IGEAF) INTA, started in 1949, with the pioneer work of Ewald Favret, who studied the effects of physical and chemical ... -
Mal de Río Cuarto virus infection causes hormone imbalance and sugar accumulation in wheat leaves
(BMC, 2019-03)Background; Mal de Río Cuarto virus (MRCV) infects several monocotyledonous species including maize and wheat. Infected plants show shortened internodes, partial sterility, increased tillering and reduced root length. To ... -
Mal de Río Cuarto Virus infection triggers the production of distinctive viral-derived siRNA profiles in wheat and Its planthopper vector
(2017)Plant reoviruses are able to multiply in gramineae plants and delphacid vectors encountering different defense strategies with unique features. This study aims to comparatively assess alterations of small RNA (sRNA) ... -
Mapping a gene on wheat chromosome 4BL involved in a complementary interaction with adult plant leaf rust resistance gene LrSV2
(Springer, 2018-08)A complementary gene to LrSV2 for specific adult plant leaf rust resistance in wheat was mapped on chromosome 4BL, tightly linked to Lr12 / 31. LrSV2 is a race-specific adult plant leaf rust (Puccinia triticina) resistance ... -
Mapping causal mutations by exome sequencing in a wheat TILLING population: a tall mutant case study
(Springer, 2018-04)Forward genetic screens of induced mutant plant populations are powerful tools to identify genes underlying phenotypes of interest. Using traditional techniques, mapping causative mutations from forward screens is a lengthy, ... -
Responses of Rhopalosiphum padi (L.) (Homoptera: Aphididae) on different wheat cultivars under laboratory conditions
(2017-06)Bird cherry-oat aphid, Rhopalosiphum padi (L.), a polyphagous species with a worldwide distribution, is an important pest of wheat as well as the main vector of barley yellow dwarf virus. The development, survivorship, and ... -
