An isopentenyl transferase transgenic wheat isoline exhibits less seminal root growth impairment and a differential metabolite profile under Cd stress
Gomez Mansur, Nabila M.; Pena, Liliana Beatriz; Bossio, Adrian Ezequiel; Lewi, Dalia Marcela; Beznec, Ailin; Blumwald, Eduardo; Arbona, Vicent; Gómez-Cadenas, Aurelio; Benavides, María Patricia; Gallego, Susana Mabel (Wiley, 2021-09)Cadmium is one of the most important contaminants and it induces severe plant growth restriction. In this study, we analyzed the metabolic changes associated with root growth restriction caused by cadmium in the early ... -
Shortening of generation cycles in inbred lines of maize (Zea mays L.) through embryo rescue technique
Liotino, Micaela; Varangot, Agostina; Beznec, Aylin; Auteri, Micol; Bossio, Adrian Ezequiel; Lewi, Dalia Marcela; Faccio, Paula Daniela (Istituto Sperimentale per la Cerealicoltura, 2019-11)Embryo rescue techniques have been used as an approach to raise hybrids from incompatible crosses. These techniques have also proved to be valuable tools for maize improvement, since they allow reducing the duration of the ... -
Silencing of the glutathione biosynthetic pathway inhibits somatic embryogenesis in wheat
Bossio, Adrian Ezequiel; Diaz Paleo, Antonio Horacio; Del Vas, Mariana; Baroli, Irene; Acevedo, Alberto; Rios, Raul Daniel (Springer, 2013-02)Somatic embryogenesis in scutella of wheat (Triticum aestivum L.) is a well documented phenomenon and it has been shown through transcriptome analysis that genes involved in antioxidant responses, particularly in glutathione ... -
Stress-induced expression of IPT gene in transgenic wheat reduces grain yield penalty under drought
Beznec, Ailin; Faccio, Paula Daniela; Miralles, Daniel J.; Abeledo, Leonor Gabriela; Decima Oneto, Cecilia Andrea; Garibotto, María De Belén; Gonzalez, Germán Andrés; Moreyra, Federico; Elizondo, Matias; Ruiz, Monica Beatriz; Lewi, Dalia Marcela; Blumwald, Eduardo; Llorente, Berta; Diaz Paleo, Antonio Horacio; Bossio, Adrian Ezequiel (Springer, 2021-05)Background: The heterologous expression of isopentenyl transferase (IPT) under the transcriptional control of the senescence-associated receptor-like kinase (SARK) promoter delayed cellular senescence and, through it, ... -
Transgenerational memory of the effect of drought stress on wheat (Triticum aestivum L.) grain yield
Becheran, Daniela E.; Abeledo, Leonor Gabriela; Beznec, Ailin; Bossio, Adrian Ezequiel; Faccio, Paula Daniela; Miralles, Daniel J. (Springer, 2023-08)Water deficit is one of the main abiotic stresses that affect wheat production worldwide. Plants exhibit phenotypic variations to mitigate the negative effects of water stress on grain yield. The objective of the work was ... -
Validation of housekeeping genes for qPCR in maize during water deficit stress conditions at flowering time
Decima Oneto, Cecilia Andrea; Bossio, Adrian Ezequiel; Faccio, Paula Daniela; Beznec, Ailin; Blumwald, Eduardo; Lewi, Dalia Marcela (2017)Plant stress studies are increasingly being based on gene expression. The analysis of gene expression requires sensitive, precise, and replicable measurements for specific mRNA sequences. Real-time RT-PCR is nowadays the ... -
Water deficit stress tolerance in maize conferred by expression of an anisopentenyltransferase (IPT) gene driven by a stress- and maturation-induced promoter
Decima Oneto, Cecilia Andrea; Otegui, María Elena; Baroli, Irene; Beznec, Ailin; Faccio, Paula Daniela; Bossio, Adrian Ezequiel; Blumwald, Eduardo; Lewi, Dalia Marcela (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 ...
