A brassinosteroid functional analogue increases soybean drought resilience
(Nature Research, 2022-07-04)Drought severely affects soybean productivity, challenging breeding/management strategies to increase crop resilience. Hormone-based biostimulants like brassinosteroids (BRs) modulate growth/defence trade-off, mitigating ... -
Un análogo de brasinoesteroide confiere tolerancia a la sequía en soja
(REDBIO, 2021-06)Los bioestimulantes a base de fitohormonas son una alternativa práctica para mitigar los efectos de la sequía en el cultivos claves como la soja. Los brasinoesteroides (BRs) promueven el crecimiento y la respuesta ... -
Changes in the relationship between temperature during the seed‐filling period and soya bean seed isoflavones under water‐deficit conditions
(Blackwell, 2016-12)Isoflavones have been shown to have health‐promoting activities in humans and are particularly abundant in soya bean. This study was conducted to determine how water deficit during seed fill affects the already known ... -
Drought controls on H2O2 accumulation, catalase (CAT) activity and CAT gene expression in wheat
(Society for Experimental Biology, 2005-01)Plants co-ordinate information derived from many diverse external and internal signals to ensure appropriate control of gene expression under optimal and stress conditions. In this work, the relationships between catalase ... -
Drought induces distinct growth response, protection, and recovery mechanisms in the maize leaf growth zone
(2015-10)Drought is the most important crop yield-limiting factor, and detailed knowledge of its impact on plant growth regulation is crucial. The maize (Zea mays) leaf growth zone offers unique possibilities for studying the ... -
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 ... -
Identificación de bacterias endófitas con efecto protector contra la sequía en plantas de maní
(Centro de Ingenieros Agrónomos General Cabrera, 2022-09-15)La variabilidad y escasez de precipitaciones estacionales generan perdidas de hasta el 30% de la cosecha de maní. Existen bacterias benéficas capaces de proteger a las plantas de los daños por sequia Esos mecanismos ... -
Identificación de Germoplasma de maní de criadero el Carmen tolerante a la sequia: aspectos bioquímicos y rendimiento
(Centro de Ingenieros Agrónomos General Cabrera, 2020-09-17)La sequía estacional es un estrés ambiental que genera pérdidas de rendimiento de alrededor del 30% en el cultivo de maní (Arachis hypogaea) en la Provincia de Córdoba. Una de las estrategias para reducirlas es el desarrollo ... -
Implicancias del estrés hídrico en la calidad forrajera de Cenchrus Ciliaris l. y su relación con la anatomía foliar y el metabolismo de la lignina
(Facultad de Ciencias Agropecuarias, Universidad Nacional de Córdoba, 2022-10-03)Cenchrus ciliaris L. es una importante gramínea forrajera distribuida en regiones áridas y semiáridas del mundo para la alimentación de ganado vacuno. En Argentina, esta especie ha sido introducida en el noroeste del país. ... -
Individual and combined effects of drought and heat on antioxidant parameters and growth performance in Buffel grass (Cenchrus ciliaris L.) genotypes
(2018-11)Drought and heat stress are two critical threats to crop growth and sustainable agriculture worldwide. In the last decade, many studies focused on the response of crops to a single stress, nevertheless studying the response ... -
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 ... -
Low water availability increases susceptibility to peanut smut (Thecaphora frezzii) in peanut crop
(Wiley, 2023-10-23)Peanut smut (causal agent Thecaphora frezzii) and seasonal drought are the two main factors reducing peanut yields in Argentina. There are no previous studies about the effect of drought on peanut smut occurrence. We ... -
