Contrasting adaptive responses to cope with drought stress and recovery in Cenchrus ciliaris L. and their implications for tissue lignification
(Wiley, 2020-11-12)Cenchrus ciliaris L. is a widely used species for cattle feed in arid and semi-arid regions due to good forage value and known tolerance to drought conditions. Here, we provide insights to adaptive responses of two contrasting ... -
Drought stress tolerance of Prosopis chilensis and Prosopis flexuosa species and their hybrids
(Springer, 2013-02)Natural hybridization commonly produces individuals with intermediate morphological and genetic characteristics, but their response to environmental stress is still uncertain, with some studies showing that transgressive ... -
Genome-wide data (ChIP-seq) enabled identification of cell wall-related and aquaporin genes as targets of tomato ASR1, a drought stress-responsive transcription factor
(BMC, 2014-01)Background: Identifying the target genes of transcription factors is important for unraveling regulatory networks in all types of organisms. Our interest was precisely to uncover the spectrum of loci regulated by a widespread ... -
Identificación y caracterización de los hongos micorrícicos arbusculares autóctonos en simbiosis con prosopis alba y los mecanismos fisiológicos / bioquímicos relacionados con la tolerancia a sequía
(Facultad de Ciencias Agropecuarias, Universidad Nacional de Córdoba, 2019)Prosopis alba Grisebach (algarrobo blanco) es una de las especies más importantes en el ecosistema natural del Chaco Occidental Semiárido de Argentina. Entre las estrategias para asegurar el establecimiento y el adecuado ... -
Transcript and metabolic adjustments triggered by drought in Ilex paraguariensis leaves
(Springer, 2019-08)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, ... -
Water deficit stress tolerance in maize conferred by expression of an anisopentenyltransferase (IPT) gene driven by a stress- and maturation-induced promoter
(2016)Senescence can be delayed in transgenic plants overexpressing the enzyme isopentenyltransferase (IPT) due to stress-induced increased levels of endogenous cytokinins. This trait leads to sustained photo-synthetic activity ...
