Impacts of vegetative and reproductive plasticity associated with tillering in maize crops in low-yielding environments: a physiological framework
Rotili, Diego Hernán; Sadras, Victor Oscar; Abeledo, Leonor Gabriela; Ferreyra, Juan Matías; Micheloud, José Roberto; Duarte, Gustavo; Giron, Paula; Ermácora, Matías; Maddonni, Gustavo Angel (Elsevier, 2021-05)Selection for maize (Zea mays L.) grain yield in high-yielding environments at high population densities has favored a compact phenotype tolerant to crowding stress, bearing a single, well-grained ear. However, by contributing ... -
Número de hojas y su filocrono entre distintos órdenes de vástagos en avena y cebada: impacto sobre el rendimiento
Lexow, Guillermo (Facultad de Agronomía, Universidad de Buenos Aires, 2019-09-19)La relación entre el número de hojas y su filocrono determina el momento de antesis en cultivos de avena y cebada. Diversas publicaciones han analizado la dinámica de la aparición de hojas y macollos totales; sin embargo, ... -
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 ...
