ABI1 and PP2CA phosphatases are negative regulators of Snf1-related protein kinase1 signaling in Arabidopsis

Rodrigues, Americo; Adamo, Mattia; Crozet, Pierre; Margalha, Leonor; Confraria, Ana; Martinho, Claudia; Elias, Alexandre; Rabissi, Agnese; Lumbreras, Victoria; González Guzmán, Miguel; Antoni-Alandes, Regina; Rodríguez Egea, Pedro Luís; Baena Gonzalez, Elena (American Society of Plant Biologists, 2013-10)

[EN] Plant survival under environmental stress requires the integration of multiple signaling pathways into a coordinated response, but the molecular mechanisms underlying this integration are poorly understood. Stress-derived ...
Arabidopsis PYR/PYL/RCAR Receptors Play a Major Role in Quantitative Regulation of Stomatal Aperture and Transcriptional Response to Abscisic Acid

González Guzmán, Miguel; Pizzio Bianchi, Gaston Alfredo; Antoni-Alandes, Regina; Vera Sirera, Francisco José; Merilo, Ebe; Bassel, George; Fernandez, M.A.; Holdsworth, M.J.; Perez Amador, Miguel Angel; kollist, H; Rodríguez Egea, Pedro Luís (American Society of Plant Biologists, 2012-06)

[EN] Abscisic acid (ABA) is a key hormone for plant growth, development, and stress adaptation. Perception of ABA through four types of receptors has been reported. We show here that impairment of ABA perception through ...
C2-Domain Abscisic Acid-Related Proteins Mediate the Interaction of PYR/PYL/RCAR Abscisic Acid Receptors with the Plasma Membrane and Regulate Abscisic Acid Sensitivity in Arabidopsis

RODRIGUEZ, LESIA; González Guzmán, Miguel; Díaz, Maira; Rodrigues, Americo; Izquierdo García, Ana Cristina; Peirats-Llobet, Marta; Fernández López, Maria Angeles; Antoni-Alandes, Regina; Fernandez, Daniel; Marquez, J.A; Mulet Salort, José Miguel; Albert, Armando; Rodríguez Egea, Pedro Luís (American Society of Plant Biologists, 2014-12)

Membrane-delimited abscisic acid (ABA) signal transduction plays a critical role in early ABA signaling, but the molecular mechanisms linking core signaling components to the plasma membrane are unclear. We show that ...
Calcium-dependent oligomerization of CAR proteins at cell membrane modulates ABA signaling

Diaz, Maira; Sanchez-Barrena, Maria Jose; Gonzalez Rubio, Juana Maria; Rodríguez Solovey, Leisa Natacha; Fernández, Daniel; Antoni-Alandes, Regina; Yunta, Cristina; Belda Palazón, Borja; González Guzmán, Miguel; Peirats-Llobet, Marta; Menendez, Margarita; Boskovic, Jasminka; Marquez, Jose; Rodríguez Egea, Pedro Luís; Albert, Armando (National Academy of Sciences, 2016-01-19)

[EN] Regulation of ion transport in plants is essential for cell function. Abiotic stress unbalances cell ion homeostasis, and plants tend to readjust it, regulating membrane transporters and channels. The plant hormone ...
Hydrotropism: Analysis of the Root Response to a Moisture Gradient

Antoni-Alandes, Regina; Dietrich, Daniela; Bennett, Malcolm J.; Rodríguez Egea, Pedro Luís (Springer New York, 2016)

[EN] Hydrotropism is a genuine response of roots to a moisture gradient to avoid drought. An experimental system for the induction of hydrotropic root response in petri dishes was designed by pioneering groups in the fi ...
PYL8 mediates ABA perception in the root through non-cell-autonomous and ligand-stabilization-based mechanisms

Belda-Palazón, Borja; Gonzalez-Garcia, Mary-Paz; LOZANO JUSTE, JORGE; Coego Gonzalez, Alberto; Antoni-Alandes, Regina; Julian-Valenzuela, Jose; Peirats-Llobet, Marta; Rodríguez Solovey, Leisa Natacha; Berbel Tornero, Ana; Dietrich, Daniela; FERNÁNDEZ LÓPEZ, MARIA ANGELES; MADUEÑO ALBI, FRANCISCO; Bennett, Malcolm J.; Rodríguez Egea, Pedro Luís (Proceedings of the National Academy of Sciences, 2018)

[EN] The phytohormone abscisic acid (ABA) plays a key role regulating root growth, root system architecture, and root adaptive responses, such as hydrotropism. The molecular and cellular mechanisms that regulate the action ...
PYRABACTIN RESISTANCE1-LIKE8 plays an important role for the regulation of abscisic acid signaling in root

Antoni-Alandes, Regina; González Guzmán, Miguel; Rodriguez, Lesia; Peirats-Llobet, Marta; Pizzio Bianchi, Gaston Alfredo; Fernández, Maria A.; De Winne, Nancy; De Jaeger, Geert; Dietrich, Daniela; Bennett, Malcolm J.; Rodríguez Egea, Pedro Luís (American Society of Plant Biologists, 2013-02)

[EN] Abscisic acid (ABA) signaling plays a critical role in regulating root growth and root system architecture. ABA-mediated growth promotion and root tropic response under water stress are key responses for plant survival ...
Selective Inhibition of Clade A Phosphatases Type 2C by PYR/PYL/RCAR Abscisic Acid Receptors

Antoni-Alandes, Regina; González Guzmán, Miguel; Rodriguez, Lesia; Rodrigues, Americo; Pizzio Bianchi, Gaston Alfredo; Rodríguez Egea, Pedro Luís (American Society of Plant Biologists, 2012-02)

[EN] Clade A protein phosphatases type 2C (PP2Cs) are negative regulators of abscisic acid (ABA) signaling that are inhibited in an ABA-dependent manner by PYRABACTIN RESISTANCE1 (PYR1)/PYR1-LIKE (PYL)/REGULATORY COMPONENTS ...
Structural insights into PYR/PYL/RCAR ABA receptors and PP2Cs

Santiago Cuéllar, Julia; Dupeux, Florine; Betz, Katja; Antoni-Alandes, Regina; González Guzmán, Miguel; Rodriguez, Lesia; Márquez, José Antonio; Rodríguez Egea, Pedro Luís (Elsevier, 2012-01)

[EN] Abscisic acid (ABA) plays an essential function in plant physiology since it is required for biotic and abiotic stress responses as well as control of plant growth and development. A new family of soluble ABA receptors, ...
The PYL4 A194T mutant uncovers a key role of PYL4-PP2CA interaction for ABA signaling and plant drought resistance

Pizzio Bianchi, Gaston Alfredo; Rodriguez, Lesia; Antoni-Alandes, Regina; González Guzmán, Miguel; Yunta, Cristina; Merilo, Ebe; Kollist, Hannes; Albert, Armando; Rodríguez Egea, Pedro Luís (American Society of Plant Biologists, 2013-09)
