Physiological and morphological short-term responses to light and temperature in two Nothofagus species of Patagonia, South America
(2012-12)
The study of plant responses to environmental stress factors is essential for management of plant systems and for anticipating their response to climate change. The main goal of this study was to determine morphological ...
Effects of catalase on chloroplast arrangement in Opuntia streptacantha chlorenchyma cells under salt stress
(Nature Publishing Group, 2017)
Transcript and metabolic adjustments triggered by drought in Ilex paraguariensis leaves
(Springer, 2019-05-04)
Ilex paraguariensis (yerba mate) is cultivated in the subtropical region of South America, where the occurrence of drought episodes limit yield. To explore the mechanisms that allow I. paraguariensis to overcome dehydration, ...
Developmental plasticity in Arabidopsis thaliana under combined cold and water deficit stresses during flowering stage
(Springer, 2021-01)
In nature, plants are exposed to multiple and simultaneous abiotic stresses that influence their growth, development, and reproduction. In the last years, the study of combined stresses has aroused the interest to know the ...
Morpho-physiological traits associated with drought responses in soybean
(Crop Science Society of America, 2021-01)
Drought is currently a major constraint to soybean [Glycine max (L.) Merr.] production worldwide and is becoming more widespread due to increased aridity and warmer temperatures in the context of global climate change. In ...
Biochemical profiles and physicochemical parameters of beef from cattle raised under contrasting feeding systems and pre-slaughter management
(Csiro Publishing, 2015-04)
Diet and pre-slaughter stress are key factors that may affect the biochemical processes during conversion of muscle into meat. The aim of the present study was to evaluate the effect of two different pre-slaughter stress ...
Physiological, biochemical, and anatomical responses of Araucaria araucana seedlings to controlled water restriction
(Elsevier France-Editions Scientifiques Medicales Elsevier, 2021-08)
Water stress triggers acclimation responses and can damage plants, which varies by species and stress levels. Ongoing climate change is projected to result in longer and more intense water stress conditions leading to an ...
Attenuation effects of prenatal stress by early postnatal stimulation in different research models
(MedCrave, 2018-09)
Prenatal stress alters the pattern of corticoid secretion and affects transplacentally the fetus hypothalamic-pituitary-adrenal axis (HPA) in different animal models. Early postnatal stimulation or handling results in an ...
Physiological stress in captive Greater rheas (Rhea americana): Highly sensitive plasma corticosterone response to an ACTH challenge
(Academic Press Inc Elsevier Science, 2009-12)
Up to the present no studies have been conducted either on baseline concentrations of adrenal hormones or on hormonal responses to stress in Greater rhea (Rhea americana) and most ratite species. The aims of this work were ...
