Detecting sources of resistance to multiple diseases in Argentine maize (Zea mays L.) germplasm
(Springer Nature, 2022-04)Maize (Zea mays L.), an important cereal for human and animal nutrition, is usually affected by multiple co-occurring pathogens that reduce production. Argentina is the fourth maize producer worldwide, with common rust ... -
Enfermedades del girasol : sclerotinia sclerotiorum (Moho blanco) = Sclerotinia sclerotiorum Diseases of Sunflower (White mold)

First report of spot lesion of wheat caused by Pyrenophora teres f. sp maculata observed in Argentina
(2019-08)Pyrenophora tritici-repentis, causal agent of tan spot, is the species commonly associated with leaf spotting symptoms on wheat (Triticum aestivum L.) worldwide and in Argentina. On the other hand, P. teres is a major ... -
Genomics-assisted breeding for quantitative disease resistances in small-grain cereals and maize
(MDPI, 2020-12-19)Generating genomics-driven knowledge opens a way to accelerate the resistance breeding process by family or population mapping and genomic selection. Important prerequisites are large populations that are genomically ... -
Germination and infection of Phakopsora pachyrhizi under simulated environment of the central area of Santa Fe, Argentina
(2016)Soybean asian rust (SAR) caused by the fungus Phakopsora pachyrhizi was confirmed in Argentina for the first time during the 2002-2003 growing season. Then, the disease spread to the Northern and Eastern provinces, reaching ... -
Importancia, toxicogénesis y agresividad de especies pertenecientes a Gibberella fujikuroi en maíz en el Noroeste Argentino = Importance, Fumonisin production and aggressiveness of Gibberella fujikuroi complex recovered from maize in northwestern Argentina
(Facultad de Agronomía y Zootecnia, Universidad Nacional de Tucumán, 2013-12)Se estudió la composición, patogenicidad y toxicogénesis de aislamientos pertenecientes al complejo Gibberella fujikuroi en una de las regiones productoras de maíz de la región Noroeste de Argentina. Los resultados evidencian ... -
Map overlapping of QTL for resistance to Fusarium ear rot and associated traits in maize
(Springer, 2021-04)Mapping QTL for disease resistance and associated traits is important to develop maize (Zea mays L.) hybrids less susceptible to ear rots. A biparental mapping population of 298 F5 recombinant inbreds (RIs), obtained from ... -
Molecular mapping of Asian soybean rust resistance in soybean landraces PI 594767A, PI 587905 and PI 416764
(Wiley, 2015-02)Asian soybean rust (ASR), caused by Phakopsora pachyrhizi, is one of the most serious diseases of soybean. The soybean landraces PI 594767A, PI 587905 and PI 416764 previously showed high levels of resistance to a wide ... -
Multi-parent QTL mapping reveals stable QTL conferring resistance to Gibberella ear rot in maize
(Springer, 2020-12)Maize production is on risk by Gibberella ear rot (GER) caused by Fusarium graminearum. This is one of the most important ear rot diseases in temperate zones as it leads to yield losses and production of harmful mycotoxins. ... -
Multi-parental QTL mapping of resistance to white spot of maize (Zea mays) in southern Brazil and relationship to QTLs of other foliar diseases
(Wiley, 2021-10)Maize white spot (MWS) is one of the most important foliar diseases in Brazil causing significant yield losses. Breeding genotypes with MWS resistance is the most sustainable alternative for managing such losses; however, ... -
No Common Candidate Genes for Resistance to Fusarium graminearum, F. proliferatum, F. sporotrichioides, and F. subglutanins in Soybean (Glycine max L.) Accessions from Maturity Groups 0 and I: Findings from Genome-Wide Association Mapping
(The American Phytopathological Society, 2024-04)Seedling diseases and root rot, caused by species of Fusarium, can limit soybean (Glycine max L.) production in the United States. Currently, there are few commercially available cultivars resistant to Fusarium. This study ... -
Pathogenic diversity of soybean rust in Argentina, Brazil, and Paraguay
(Springer, 2013-01)Phakopsora pachyrhizi, the cause of soybean rust, is an economically important pathogen of soybean in South America. Understanding the pathogenicity of indigenous fungal populations is useful for identifying resistant plant ... -
Phenylpropanoids from maize pericarp: resistance factors to kernel infection and fumonisin accumulation by Fusarium verticillioides
(Springer, 2013-01)The aim of this work was to investigate the role of pericarp phenylpropanoids as resistance factors to F. verticillioides in eleven maize genotypes. Disease severity and kernel fumonisin accumulation were measured after ... -
Timing is everything: how planting period shapes nutritional quality, mycobiota characteristics, and mycotoxin contamination in maize (Zea mays) grains
(Springer Nature, 2024-01)Maize (Zea mays L.) is crucial in global grain markets and food/feed production. Fungal contamination in ears can adversely affect crop yield and diminish the nutritional value of grains. Moreover, many of the main pathogens ... -
Unravelling the complexity of maize resistance to bacterial and fungal diseases: an integrative perspective
(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
(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 ...
