Deciphering the transcriptomic regulation of heat stress responses in Nothofagus pumilio
Estravis Barcala, Maximiliano; Heer, Katrin; Marchelli, Paula; Ziegenhagen, Birgit; Arana, María Veronica; Bellora Pereyra, Nicolás (Plos One, 2021-03-30)Global warming is predicted to exert negative impacts on plant growth due to the damaging effect of high temperatures on plant physiology. Revealing the genetic architecture underlying the heat stress response is therefore ... -
Effect of temperature on circadian clock functioning of trees in the context of global warming
Estravis Barcala, Maximiliano; Gaischuk, Sofia; Gonzalez Polo, Marina; Martinez Meier, Alejandro; Gutiérrez, Rodrigo A.; Yanovsky, Marcelo J.; Bellora Pereyra, Nicolás; Arana, María Veronica (Wiley, 2025-01)Plant survival in a warmer world requires the timely adjustment of biological processes to cyclical changes in the new environment. Circadian oscillators have been proposed to contribute to thermal adaptation and plasticity. ... -
Environmental gradients as “natural labs” for elucidating the regeneration dynamics of three Nothofagus species under different climatic scenarios in Patagonia
Cagnacci, Julieta Maria; Estravis Barcala, Maximiliano; Gonzalez-Polo, Marina; Marchelli, Paula; Pastorino, Mario Juan; Martinez Meier, Alejandro; Batlla, Diego; Arana, María Veronica (2018-09)We work in Patagonian forests, the southernmost woody ecosystems of the world, in which three tree species have a clear altitudinal distribution. Nothofagus obliqua is frequent at 650-850 m above the sea level, N. nervosa ... -
Molecular bases of responses to abiotic stress in trees
Estravis Barcala, Maximiliano; Mattera, María Gabriela; Soliani, Carolina; Bellora Pereyra, Nicolás; Opgenoorth, Lars; Heer, Katrin; Arana, María Veronica (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 ... -
Physiological and molecular mechanisms underlying the integration of light and temperature cues in Arabidopsis thaliana seeds
Arana, María Veronica; Tognacca, Rocío Soledad; Estravis Barcala, Maximiliano; Sanchez, Rodolfo Augusto; Botto, Javier Francisco (Wiley, 2017-09-23)The relief of dormancy and the promotion of seed germination are of extreme importance for a successful seedling establishment. Although alternating temperatures and light are signals promoting the relief of seed dormancy, ... -
Respuestas a la temperatura en especies del género Nothofagus distribuidas en un gradiente altitudinal
Estravis Barcala, Maximiliano (Edición del Autor, 2019-03-07)Las predicciones del Cambio Clim´atico Global para el noroeste de la Patagonia indican un aumento de la temperatura media, acompañado de mayor frecuencia de eventos extremos. En este contexto, es fundamental comprender la ... -
The impact of different natural environments on the regeneration dynamics of two Nothofagus species across elevation in the southern Andes
Cagnacci, Julieta Maria; Estravis Barcala, Maximiliano; Lia, Veronica Viviana; Martinez Meier, Alejandro; Gonzalez Polo, Marina; Arana, María Veronica (Elsevier, 2020-05-15)A widely accepted paradigm in forest ecology proposes that patterns of relative abundance among mature forest trees are largely influenced by biotic and abiotic processes that operate most intensely during the earliest ...
