Functional diversity of phytochrome family in the control of light and gibberellin-mediated germination in Arabidopsis
Arana, María Veronica; Sanchez Lamas, Maximiliano; Strasser, B.; Ibarra, Silvia E.; Cerdan, Pablo Diego; Botto, Juan Francisco; Sanchez, Rodolfo Augusto (Wiley, 2014-03)In several species, seed germination is regulated by light in a way that restricts seedling emergence to the environmental conditions that are likely to be favourable for the success of the new individual, and therefore, ... -
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, ... -
Seed dormancy responses to temperature relate to Nothofagus species distribution and determine temporal patterns of germination across altitudes in Patagonia
Arana, María Verónica; Gonzalez Polo, Marina; Martinez Meier, Alejandro; Gallo, Leonardo Ariel; Benech-Arnold, Roberto Luis; Sanchez, Rodolfo Augusto; Batlla, Diego (2015-08-26)Seeds integrate environmental cues that modulate their dormancy and germination. Although many mechanisms have been identified in laboratory experiments, their contribution to germination dynamics in existing communities ...
