Co-expression networks in sunflower : harnessing the power of multi-study transcriptomic public data to identify and categorize candidate genes for fungal resistance
(MDPI, 2023-08)Fungal plant diseases are a major threat to food security worldwide. Current efforts to identify and list loci involved in different biological processes are more complicated than originally thought, even when complete ... -
Complete genome sequence of sunflower ring blotch virus, a new potyvirus infecting sunflower in Argentina
(Springer, 2017-06)The complete genome sequence of sunflower ring blotch virus (SuRBV), a previously undescribed potyvirus infecting sunflower in Argentina, is reported. The SuRBV genome comprises 9555 nucleotides (nt) and encodes a polyprotein ... -
La convergencia de los precios Agrícolas de la Argentina y de los EE.UU. la “ley de un solo precio” para los commodities pampeanos
(Instituto de Economía y Sociología, INTA, 1998-11)En el trabajo se postula la hipótesis que los precios recibidos por los productores de la Argentina y los EE.UU., para cuatro commodities agrícolas (trigo, maíz, soja y girasol), fueron arbitrados en forma consistente entre ... -
Development, characterization and experimental validation of a cultivated sunflower (Helianthus annuus L.) gene expression oligonucleotide microarray
(PLOS One, 2012-10)Oligonucleotide-based microarrays with accurate gene coverage represent a key strategy for transcriptional studies in orphan species such as sunflower, H. annuus L., which lacks full genome sequences. The goal of this study ... -
Exploring sunflower responses to Sclerotinia head rot at early stages of infection using RNA‑seq analysis
(Springer Nature, 2020-08)Sclerotinia head rot (SHR), caused by the necrotrophic fungus Sclerotinia sclerotiorum, is one of the most devastating sunflower crop diseases. Despite its worldwide occurrence, the genetic determinants of plant resistance ... -
El fenómeno ENSO y la agricultura pampeana: impactos económicos en trigo, maíz, girasol y soja
(Instituto de Economía y Sociología, INTA, 1998-09)Se presentan estimaciones económicas de los efectos del cambio climático generado por las fases del fenómeno ENSO sobre la agricultura pampeana para los cultivos de trigo, maíz, girasol y soja. Se estimó el diferencial de ... -
Genetic variability for responses to short‐ and long‐term salt stress in vegetative sunflower plants
(Wiley, 2012-12)Sunflower (Helianthus annuus L.) has been rated as moderately salt‐resistant, and variability for salt resistance has been detected within this crop. However, variability in salt‐resistance mechanisms has not been assessed. ... -
Genome-wide and comparative phylogenetic analysis of senescence-associated NAC transcription factors in sunflower (Helianthus annuus)
(Springer, 2021-12)Background: Leaf senescence delay impacts positively in grain yield by maintaining the photosynthetic area during the reproductive stage and during grain filling. Therefore a comprehensive understanding of the gene families ... -
Genome-wide association studies in sunflower : towards sclerotinia sclerotiorum and diaporthe/phomopsis resistance breeding
(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 ... -
On-field phenotypic evaluation of sunflower populations for broad-spectrum resistance to Verticillium leaf mottle and wilt
(Springer Nature, 2021-06)Sunflower Verticillium Wilt and Leaf Mottle (SVW), caused by Verticillium dahliae (Kleb.; Vd), is a soil-borne disease affecting sunflower worldwide. A single dominant locus, known as V1, was formerly effective in controlling ... -
Peculiarities of the Transformation of Asteraceae Family Species: The Cases of Sunflower and Lettuce
(Frontiers Publishing, 2021-11)The Asteraceae family is the largest and most diversified family of the Angiosperms, characterized by the presence of numerous clustered inflorescences, which have the appearance of a single compound flower. It is estimated ... -
Phenotyping sunflower genetic resources for Sclerotinia head rot response: assessing variability for disease resistance breeding
(The American Phytopathological Society, 2017-11)Sclerotinia head rot (SHR) is one of the most serious constraints to sunflower (Helianthus annuus L. var. macrocarpus) production worldwide. Here, we evaluated the response to SHR in a sunflower inbred panel from a large ... -
Phylodynamics of sunflower chlorotic mottle virus, an emerging pathosystem
(Elsevier, 2020-03-12)Distribution and epidemiological patterns of sunflower chlorotic mottle virus (SCMoV) in sunflower (Helianthus annuus L.) growing areas in Argentina were studied from 2006 to 2017. The virus was detected exclusively in ... -
