Expressing the sunflower transcription factor HaHB11 in maize improves waterlogging and defoliation tolerance
(Oxford University Press, 2022-05)The sunflower (Helianthus annuus) transcription factor HaHB11 (H. annuus Homeobox 11) belongs to the homeodomain-leucine zipper family and confers improved yield to maize (Zea mays) hybrids (HiII × B73) and lines. Here we ... -
Breeding effects on canopy light attenuation in maize: a retrospective and prospective analysis
(Oxford University Press, 2022-03)The light attenuation process within a plant canopy defines energy capture and vertical distribution of light and nitrogen (N). The vertical light distribution can be quantitatively described with the extinction coefficient ... -
Maize genetic progress in the central Pampas of Argentina: effects of contrasting sowing dates
(Elsevier, 2022-05)Delayed sowing date of maize (Zea mays L.) has become a broadly adopted practice in the Pampas region of Argentina, because late-sown crops frequently experience a more favorable water balance around flowering and a reduction ... -
Environment affects starch composition and kernel hardness in temperate maize
(Wiley, 2022-03)BACKGROUND: Protein percentage and kernel weight affect the endosperm hardness of maize grains. However, changes in starch composition could also modify kernel hardness, which is often predicted through milling ratio. The ... -
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 ... -
Cane molasses and oligofructose in the diet of laying hens improves the mineral content of eggs and meat
(Elsevier, 2022-06)Poultry-based foods contribute to human health due to their high nutrient value. Previously, it was shown that short-chain fatty acids (SCFAs) produced by in vitro intestinal fermentation of a molasses and oligofructose ... -
Classification of argentine maize landraces in heterotic groups
(Consiglio per la Ricerca in Agricoltura e l'Analisi dell'Economia Agraria, 2012)The genetic diversity of maize (Zea mays L) is a valuable and strategic natural resource that plays a key role in the breeding progress. However, exploitation of genetic variability from landraces has not reached a significant ... -
Cover crop mixtures increase ecosystem multifunctionality in summer crop rotations with low N fertilization
(Springer Nature, 2022)Cropping diversification with cover crop mixtures combined with low N fertilization represents an ecological alternative that may promote sustainability. Our objective was to evaluate changes on soil organic fractions and ... -
The Use of Detached Leaf Inoculation for Selecting Cercospora kikuchii Resistance in Soybean Genotypes
(The American Phytopathological Society (APS), 2021-11)Cercospora leaf blight (CLB) causes extensive losses in soybean production in worldwide, including major soybean-producing countries such as Argentina. Cercospora kikuchii, C. cf. sigesbeckiae, C. cf. flagellaris, and C. ... -
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 ... -
Relative performance of cluster algorithms and validation indices in maize genome-wide structure patterns
(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 ... -
Yield determinants, root distribution and soil water uptake in maize (Zea mays) hybrids differing in canopy senescence under post-silking drought
(CSIRO Publishing, 2021-05)Delayed canopy senescence or ‘stay-green’ (SG) trait in maize (Zea mays L.) could improve drought tolerance. Two field trials comparing four to six maize hybrids with different senescence rate were carried out at Buenos ... -
Capacity and Intensity Indicators to evaluate the effect of different crop sequences and cover crops on soil physical quality of two different textured soils from Pampas Region
(Elsevier, 2021-11)Soil physical degradation is a current problem in Molisols of the Pampas Region under no-tillage (NT), that has been related to over-simplified agricultural systems with scarce or no rotations and long winter bare fallows. ... -
Junglerice (Echinochloa colonaL.) seedling emergence model as a tool to optimize pre-emergent herbicide application
(Italian Society for Agronomy, 2021-07)Junglerice (Echinochloa colona), one of the worst and most problematic weeds globally, causes significant economic losses due to yield loss and control cost increase. Taking into account that this weed emerges in approximately ... -
Analysis of molecular mobility in corn and quinoa flours through ¹H NMR and its relationship with water distribution, glass transition and enthalpy relaxation
(Elsevier, 2021-03)Solids-water interactions of corn and quinoa flours were evaluated through 1H NMR, DSC, and water sorption isotherms. Glass transition temperature (Tg), observed by DSC, was better distinguished through FID signals, and ... -
Phosphorus and nitrogen fractions during base flow conditions of a Pampean stream and their relationship with land use
(Asociación Argentina de Ecología, 2020-12)During the last decades, population growth and the associated intensification of anthropogenic activities (agriculture, industrialization and urbanization) increased nutrient inputs to Pampean lotic waterbodies. However, ... -
Comportamiento dinámico del peso del huevo en gallinas camperas discriminadas por indicadores productivos a la madurez sexual
(Facultad de Ciencias Veterinarias, Universidad Nacional de La Pampa, 2020-10-29)The effects on the dynamic pattern of egg weight of five traits at sexual maturity were characterized in Campero Casilda hens. When the first egg was laid, body weight, age (an indicator of sexual precocity), weight of ... -
