Cryptochromes are the dominant photoreceptors mediating heliotropic responses of Arabidopsis inflorescences
(Wiley, 2021-10)Inflorescence movements in response to natural gradients of sunlight are frequently observed in the plant kingdom and are suggested to contribute to reproductive success. Although the physiological and molecular bases of ... -
Estudio de los cambios transcriptómicos producidos por infecciones virales en plantas, rol de fitohormonas y su vinculación con la progresión de síntomas
(Facultad de Ciencias Exactas y Naturales, Universidad de Buenos Aires, 2014-08)Las pérdidas en cultivos ocasionadas por virus dependen mayormente de la severidad de los síntomas producidos. La comprensión de los mecanismos moleculares que subyacen a la producción de síntomas es de importancia para ... -
Fungal-derived extracts induce resistance against Botrytis cinerea in Arabidopsis thaliana
(Springer, 2020-06)Development of a sustainable agriculture is a current trend searching for alternative and more environmentally friendly strategies to control crop diseases. The necrotrophic fungus Botrytis cinerea, the causal agent of ... -
High Sugar Concentration Inhibits TOR Signaling Pathway in Arabidopsis thaliana
(Springer, 2023-01-20)Sugars are not only energy sources, but also central molecular signals that regulate growth, development, and response to environmental stresses. It is well recognized that sugars activate TOR kinase, the key integrator ... -
Involvement of nitrate reductase (NR) in osmotic stress-induced NO generation of Arabidopsis thaliana L. roots
(Elsevier, 2010-01)Nitric oxide (NO) is undoubtedly a potential signal molecule in diverse developmental processes and stress responses. Despite our extensive knowledge about the role of NO in physiological and stress responses, the source ... -
Participación del antiporter NA+/H+ NHX1 de Lotus tenuis en la tolerancia a la salinidad de arabidopsis thaliana
(Sociedad Argentina de Genética, 2023-10)Lotus tenuis es una leguminosa forrajera naturalizada en los campos bajos de la Pampa Deprimida. El antiporter vacuolar NHX1 es fundamental en la tolerancia a la salinidad de numerosas especies por ser responsable de la ... -
Physiological and molecular mechanisms underlying the integration of light and temperature cues in Arabidopsis thaliana seeds
(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, ... -
Rewatering Plants after a Long Water-deficit Treatment Reveals that Leaf Epidermal Cells Retain their Ability to Expand after the Leaf has Apparently Reached its Final Size
(Oxford Academic Press, 2008-05)Background and Aims: Leaves expand during a given period of time until they reach their final size and form, which is called determinate growth. Duration of leaf expansion is stable when expressed in thermal-time and in ... -
The conserved brassinosteroid-related transcription factor BIM1a negatively regulates fruit growth in tomato
(Oxford University Press, 2021-02)Brassinosteroids (BRs) are steroid hormones that play key roles in plant development and defense. Our goal is to harness the extensive knowledge of the Arabidopsis BR signaling network to improve productivity in crop ...
