Morphological diversity of populations of the genus Prosopis in the semiarid Chaco of northern Cordoba and southern Santiago Del Estero
(Scientific Research, 2013-11)The objective of this study consisted in the characterization of morphological variability presented in the Prosopis population in the corridor that unites the semiarid with the arid region in Argentina. In this region, ... -
Morpho‐physiological traits associated with drought responses in soybean (Glycine max L.)
(2020-08-26)Drought is currently a major constraint to soybean production worldwide and is becoming more widespread due to increased aridity and warmer temperatures in the context of global climate change. In this context, breeding ... -
Negative short-term salt effects on the soybean–Bradyrhizobium japonicum interaction and partial reversion by calcium addition
(CSIRO Publishing, 2013-09-05)The short-term (2 h) effects of salt stress (50 and 150 mM NaCl) on early events of soybean– Bradyrhizobium japonicum (rhizobia) interaction were analysed, determining the following parameters in root hair with or without ... -
New insights into the molecular basis of induced resistance triggered by potassium phosphite in potato
(2019-11-12)This work aimed to provide data about the molecules involved in induced resistance mediated by potassium phosphite (KPhi) in potato. To achieve these, we performed microarray analysis to determine the changes in gene ... -
Nivel de ADN-Ploidía en poblaciones sudamericanas y norteamericanas de la gramínea nativa disyunta Trichloris crinita (Chloridoideae, Poaceae)
(Facultad de Ciencias Agrarias, Universidad Nacional del Litoral, 2021-04-24)Trichloris crinita es una gramínea nativa de distribución disyunta que habita regiones áridas y semiáridas de Sud y Norteamérica. Trabajos previos mostraron uniformidad en el nivel de ploidía en poblaciones sudamericanas ... -
Nurse plants and seed provenance in the restoration of dry Chaco forests of central Argentina
(Elsevier, 2023-02-01)In degraded dry environments, a promising restoration strategy involves nurse plants and their microsites, which facilitate species recruitment. Different nurse plant species might provide different microclimatic and soil ... -
Nutrient deficiency and hypoxia as constraints to Panicum coloratum growth in alkaline soils
(Wiley; British Grassland Society; European Grassland Federation, 2017-12)Alkaline and saline–alkaline soils impose severe restrictions on plant growth. Panicum coloratum var. coloratum is a perennial C4 forage grass widely used in tropical and subtropical environments. Published information on ... -
Obtaining sexual genotypes for breeding in buffel grass
(2013-09)Buffel grass (Cenchrus ciliaris L. syn. Pennisetum ciliare (L.) Link) is a species that is highly tolerant to drought and is used primarily as forage in drier regions throughout the subtropics and tropics. It reproduces ... -
Partial and total defoliation during the filling period affected grain industrial and nutraceutical quality in soybean
(Wiley, 2022-01-08)BACKGROUND: Little is known about soybean grain chemical composition response to defoliation. The objectives of our study were: (i) to quantify the impact of different levels and timing of defoliation during the filling ... -
Phosphatidylinositol 3-kinase function at very early symbiont perception: a local nodulation control under stress conditions?
(Society for Experimental Biology, 2018-04)Root hair curling is an early and essential morphological change required for the success of the symbiotic interaction between legumes and rhizobia. At this stage rhizobia grow as an infection thread within root hairs and ... -
Physiological and anatomical traits associated with tolerance to long‐term partial submergence stress in the Lotus genus: responses of forage species, a model and an interspecific hybrid
(2018-09)Cattle production based on natural pastures is often subject to flooding periods, which affect plant performance and as a result, forage production. Although most forage legumes are not tolerant to flooding, Lotus spp. are ... -
Physiological causes for decreased productivity under high salinity in Boma, a tetraploid Chloris gayana cultivar
(CSIRO Publishing, 2001)Rhodes grass (Chloris gayana Kunth) is widely cultivated in the semi-arid tropics and favoured for salt tolerance; nevertheless, productivity decreases significantly under saline conditions, especially in tetraploid ... -
Physiological characterization of four model Lotus diploid genotypes: L. japonicus (MG20 and Gifu), L. filicaulis, and L. burttii under salt stress
(Elsevier, 2009-09-25)The genus Lotus comprises a heterogeneous group of annual and perennial species. Lotus japonicus (with MG20 and Gifu ecotypes) has been adopted as one of the model legumes in genetic and genomic studies. Other Lotus species, ... -
Plant Biology: New Insight into How Roots 'Mask Up'
(Cell Press, 2021-03-08)Extra- and trans-cellular barriers are essential for root function under even mild stress. New research shows that establishing both the lignin and suberin barriers in the Arabidopsis endodermis requires phenylpropanoid ... -
Plasticity in sunflower leaf and cell growth under high salinity
(Wiley, 2015-01)A group of sunflower lines that exhibit a range of leaf Na+ concentrations under high salinity was used to explore whether the responses to the osmotic and ionic components of salinity can be distinguished in leaf expansion ... -
Polyamines and flavonoids : key compounds in mycorrhizal colonization of improved and unimproved soybean genotypes
(Springer, 2018-11)Modern breeding programs might have caused a reduction in plant responsiveness to arbuscular mycorrhizal fungi (AMF). Flavonoids and polyamines (PAs) are hypothesized to play a role in this symbiosis. We tested the effects ... -
Polyamines and Legumes: Joint Stories of Stress, Nitrogen Fixation and Environment
(Frontiers Media, 2019-11-04)Polyamines (PAs) are natural aliphatic amines involved in many physiological processes in almost all living organisms, including responses to abiotic stresses and microbial interactions. On other hand, the family Leguminosae ... -
Potential Uses of Wild Germplasms of Grain Legumes for Crop Improvement
