[EN] Cell expansion is an increase in cell size and thus plays an essential role in plant growth and development. Phytohormones and the primary plant cell wall play major roles in the complex process of cell expansion. In ...
Auxin methylation is required for differential growth in Arabidopsis

Abbas, Mohamad; Hernández-García, Jorge; Pollmann, Stephan; Samodelov, S.L.; Kolb, M.; Friml, J.; Hammes, U.; Zurbriggen, M.D.; Blazquez Rodriguez, Miguel Angel; Alabadí Diego, David (Proceedings of the National Academy of Sciences, 2018-06-26)

[EN] Asymmetric auxin distribution is instrumental for the differential growth that causes organ bending on tropic stimuli and curvatures during plant development. Local differences in auxin concentrations are achieved ...
Bases moleculares de la síntesis de termoespermina y sus implicaciones en el desarrollo vascular de Arabidopsis thaliana

Vera Sirera, Francisco José (Universitat Politècnica de València, 2011-04-06)

beta-Lactam Antibiotics Modify Root Architecture and Indole Glucosinolate Metabolism in Arabidopsis thaliana

Gudiño, M.; Blanco-Touriñán, Noel; Arbona, V.; Gómez-Cadenas, Aurelio; Blazquez Rodriguez, Miguel Angel; Navarro-García, F. (Oxford University Press, 2018-10)

[EN] The presence of antibiotics in soils could be due to natural production by soil microorganisms or to the effect of anthropogenic activities. However, the impact of these compounds on plant physiology has not been ...
Can plant biotechnology help in solving our food and energy shortage in the future?

Avni, A; Blazquez Rodriguez, Miguel Angel (Elsevier, 2011-04-22)
Circadian oscillation of gibberellin signalling in Arabidopsis

Arana, María Verónica; Marín de la Rosa, Nora Alicia; Maloof, Jurin N.; Blazquez Rodriguez, Miguel Angel; Alabadí Diego, David (National Academy of Sciences, 2011-05-31)

[EN] Circadian clocks are endogenous timekeeping mechanisms that allow organisms to anticipate rhythmic, daily environmental changes. Temporal coordination of transcription results in a set of gene expression patterns with ...
Conservation of thermospermine synthase activity in vascular and non-vascular plants

Solé-Gil, Anna; Hernández-García, Jorge; López-Gresa, María Pilar; BLAZQUEZ RODRIGUEZ, MIGUEL ANGEL; AGUSTI FELIU, JAVIER (Frontiers Media SA, 2019-06-11)
