Expression of animal anti-apoptotic gene ced-9 enhances tolerance during Glycine max L.– Bradyrhizobium japonicum interaction under saline stress but reduces nodule formation
(2014-07-27)The mechanisms by which the expression of animal cell death suppressors in economically important plants conferred enhanced stress tolerance are not fully understood. In the present work, the effect of expression of animal ... -
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 ... -
Fast classification system for drought tolerance in peanut and soybean
(Sociedade Brasileira de Fisiologia Vegetal (SBFV), 2022-09-06)Drought is one of the major limitations for agriculture. The direct selection of tolerant genotypes on the fields is time consuming due to the unpredictability of the environmental conditions. Our group use a physiological ... -
Feasibility of lowering soybean planting density without compromising nitrogen fixation and yield
(American Society of Agronomy, 2014)Adjusting soybean [Glycine max (L.) Merrill] density can be critical to reduce inter-plant competition for water, nutrients, and sunlight, and to increase intercepted radiation, photosynthesis, and biomass production. The ... -
Glutathione, a key compound for As accumulation and tolerance in soybean plants treated with AsV and AsIII
(Elsevier, 2019-06)Despite soybean (Glycine max L.) is often cultivated in areas contaminated with arsenic (As) which causes deleterious effects on its growth, little is known about tolerance mechanisms in response to As exposure. In particular, ... -
Heat and water stressed field-grown soybean : a multivariate study on the relationship between physiological-biochemical traits and yield
(Elsevier, 2018-04)Heat stress (HS) combined with water stress (WS) negatively impact soybean [Glycine max (L.) Merr.] production. The aims of this research were to quantify the combined effect of HS and WS during grain filling (GF) on grain ... -
Impact of the use of nano-fertilizers in soybean crop
(Sociedade Brasileira de Fisiologia Vegetal (SBFV), 2022-09-06)In the Cerrado region, Rio Verde GO, Brazil, rural producers seek to increase the soybean productivity efficiently. The objective of this work was to develop a complementary fertilization protocol to the traditional management ... -
Impacto del manejo del cultivo de soja sobre la microbiota del suelo y la incidencia del síndrome de muerte súbita
(ACSOJA, 2019-09-04)En las últimas décadas, el proceso de agriculturización se ha destacado por el incremento del área sembrada, corrimiento de la frontera agropecuaria, dominio del cultivo de soja (S) y tecnologías de insumos (plaguicidas y ... -
Interactions between soybean, Bradyrhizobium japonicum and Soybean mosaic virus: the effects depend on the interaction sequence
(2019-06-25)The symbiotic interaction between soybean and nitrogen-fixing rhizobia can lead to plant growth promotion and induced systemic responses. Symbiotic interactions may increase tolerance/resistance to abiotic/biotic stress ... -
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 ... -
Leaf Photosynthesis and Senescence in Heated and Droughted Field-grown Soybean with Contrasting Seed Protein Concentration
(Elsevier, 2021-06-06)Soybean plants under heat and drought generate a multiplicity of responses in photosynthesis and senescence, impairing growth, yield, and seed quality. The goal of this study was to analyze and quantify independent and ... -
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 ... -
Meta‐analysis of fungicide efficacy on soybean target spot and cost–benefit assessment
(Wiley, 2018)Target spot of soybean has spread in Brazil, the southeastern United States and Argentina in the last decade. A collaborative network of field Uniform Fungicide Trials (UFT) in Brazil was created in 2011 to study the target ... -
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 ... -
Nanofertilizantes: Nematodos, micorrización y actividad microbiana en soja
(Asociación Argentina de Ecología, 2023-10-17)La soja es el cultivo más importante de la región de Rio Verde, Goiás (Brasil). El empleo de nanofertilizantes (NF) es una herramienta prometedora para aumentar la producción cuidando el medio ambiente. -
Partial and total defoliation during the filling period affected grain industrial and nutraceutical quality in soybean
