Molecular bases of responses to abiotic stress in trees
(Oxford University Press, 2020-06)Trees are constantly exposed to climate fluctuations, which vary with both time and geographic location. Environmental changes that are outside of the physiological favorable range usually negatively affect plant performance ... -
Morpho-physiological acclimation to canopy coverage of Araucaria angustifolia during the establishment in the Atlantic Forest, Argentina = Aclimatación morfo-fisiológica durante el establecimiento de Araucaria angustifolia bajo cobertura de canopeo en el Bosque Atlántico, Argentina
(Facultad de Ciencias Forestales y Recursos Naturales, Universidad Austral de Chile, 2019)Araucaria angustifolia is an ecologically and commercially important species of the Atlantic Forest. However, its ability to regenerate continuously under the shade of the canopy in the rainforest is uncertain. The aims ... -
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 ... -
mRNA biogenesis-related helicase eIF4AIII from Arabidopsis thaliana is an important factor for abiotic stress adaptation
(2016)Similar to other plant species, Arabidopsis has a huge repertoire of predicted helicases, including the eIF4AIII factor, a putative component of the exon junction complex related to mRNA biogenesis. In this article, we ... -
Multiomics analyses reveal the roles of the ASR1 transcription factor in tomato fruits
(Oxford University Press, 2021-09)The transcription factor ASR1 (ABA, STRESS, RIPENING 1) plays multiple roles in plant responses to abiotic stresses as well as being involved in the regulation of central metabolism in several plant species. However, despite ... -
Niche dynamics in amphitropical desert disjunct plants: Seeking for ecological and species‐specific influences
(Wiley, 2020-11)Numerous studies have assessed whether species niches are conserved in geographically separated regions. However, most of them were performed on invasive species, with the limitation that such species have likely not yet ... -
Oxidative stress mitigation in horticultural crops using foliar applications of Ilex paraguariensis extract: a dose-dependent study
(Wiley, 2023-11)Abiotic stress has been shown to induce the formation of reactive oxygen species (ROS) in plant cells. When the level of ROS surpasses the capacity of the endogenous defence mechanism, oxidative stress status is reached, ... -
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 ... -
