Lead uptake and translocation pathways in soybean seedlings: the role of ion competition and transpiration rates
(Springer, 2021-01-06)Glycine max (L.) Merr. (soybean) crop plants have been found to have high lead (Pb) levels in aerial organs; however, knowledge about the processes involved in the incorporation, and subsequent translocation and accumulation ... -
Assessment of lead tolerance on Glycine max (L.) Merr. at early growth stages
(Springer, 2021-01-11)Lead (Pb) contamination of agricultural soils, and subsequently of crops, has been widely reported. Soybean (Glycine max (L.) Merr.) has been indicated as a plant that accumulates Pb, even in soils that do not exceed the ... -
A proposed role for endomembrane trafficking processes in regulating tonoplast content and vacuole dynamics under ammonium stress conditions in Arabidopsis root cells
(Taylor and Francis, 2021-05-06)Ammonium (NH4+) stress has multiple effects on plant physiology, therefore, plant responses are complex, and multiple mechanisms are involved in NH4+ sensitivity and tolerance in plants. Root growth inhibition is an important ... -
Plant Tolerance Mechanisms to Soil Salinity Contribute to the Expansion of Agriculture and Livestock Production in Argentina
(Springer, 2021)This chapter addresses salt tolerance mechanisms in crops and woody species cultivated in Argentina, highlighting the contribution of local research to these topics. Work on forages and woody species represents approximately ... -
Convergent Epigenetic Mechanisms Avoid Constitutive Expression of Immune Receptor Gene Subsets
(Frontiers Media, 2021-09-07)The gene pool encoding PRR and NLR immune receptors determines the ability of a plant to resist microbial infections. Basal expression of these genes is prevented by diverse mechanisms since their hyperactivity can be ... -
Benchmarking Nutraceutical Soybean Composition Relative to Protein and Oil
(Frontiers Media, 2021-08-11)The aim of this study was to explore relationships between protein, oil, and seed weight with seed nutraceutical composition, focused on total isoflavone (TI) and total tocopherol (TT) contents across genotypic and ... -
Evaluación de Procesos Fisiológicos Involucrados en la Fotosíntesis Bajo Condiciones de Estrés Térmico e Hídrico en Soja
(Red Raíces de Ecofisiología MINCyT y el Área Estratégica de Ecofisiología del INTA, 2017-09-28)Actualmente se discute si el estrés térmico (ET) o el estrés hídrico (EH) limitan la fotosíntesis en los cultivos debido al cierre de estomas, a cambios metabólicos o a la combinación de ambos factores (Chaitanya et al., ... -
Leaf structure and ultrastructure changes induced by heat stress and drought during seed filling in field-grown soybean and their relationship with grain yield
(Academia Brasileira de Ciências, 2021)Studies focusing on terminal drought combined with heat impacts on plants of agronomic value remain scarce, and even less under field conditions. The objective of this study was to investigate leaf structural and ultrastructural ... -
Factors Affecting Tocopherol Concentrations in Soybean Seeds
(American Chemical Society, 2016-10-31)Soybean seeds contain several health-beneficial compounds, including tocopherols, which are used by the nutraceutical and functional food industries. Soybean tocopherol concentrations are, however, highly variable. Large ... -
Water Deficit Modulates the Relationship between Temperature and Unsaturated Fatty Acid Profile in Soybean Seed Oil
(Crop Science Society of America, 2017-08-23)Soybean [Glycine max (L.) Merr.], a major source of vegetable oil worldwide, contains unsaturated fatty acids (UFA) beneficial for human health, leading to the use of soybean oil in nutraceuticals. The objective of this ... -
Provenance matters: variability under saline stress in young plants of four populations of a Prosopis (mesquite) species from dry forests of Argentina
(Canadian Science Publishing, 2021-01-04)The planting of native perennial woody species tolerant to variable salt concentrations can facilitate the recovery of degraded dry forests. The objective of this study was to evaluate and compare, under experimentally ... -
Prospective genetic gain to improve salinity tolerance in a population of Panicum coloratum var. coloratum with two different selection methods
(CIAT, 2021)Panicum coloratum var. coloratum is a subtropical grass for potentially increasing forage production in lowly productive environments where cattle-raising activities have been relocated. Heritability was estimated for ... -
Breeding for Drought Tolerance by Monitoring Chlorophyll Content
(Longdom Publishing, 2021-05-17)Crop yields have increased substantially during the last 50 years, but the traits that drove these remarkable improvements, such as plant architecture, have a little remaining potential for improvement. New traits such ... -
Composición de tocoferoles en soja bajo estrés térmico e hídrico durante el llenado de grano: variación según la posición en el canopeo
