A novel role for protein kinase Gcn2 in yeast tolerance to intracellular acid stress

Hueso Lorente, Guillem; Aparicio Sanchis, Rafael; Montesinos De Lago, Consuelo; Lorenz, Silvia; Murguía Ibáñez, José Ramón; Serrano Salom, Ramón (Portland Press, 2012)

Intracellular pH conditions many cellular systems, but its mechanisms of regulation and perception are mostly unknown. We have identified two yeast genes important for tolerance to intracellular acidification caused by ...
A thermodynamic switch modulates abscisic acid receptor sensitivity

Dupeux, Florine; Santiago Cuéllar, Julia; Betz, Katja; Twycross, Jamie; Park, Sangyoung; Rodriguez, Lesia; González Guzmán, Miguel; Jensen, Malene Ringkjobing; Krasnogor, Natalio; Blackledge, Martin; Holdsworth, Michael; Cutler, Sean R.; Rodríguez Egea, Pedro Luís; Marquez, Jose Antonio (EMBO Press, 2011-10-19)

[EN] Abscisic acid (ABA) is a key hormone regulating plant growth, development and the response to biotic and abiotic stress. ABA binding to pyrabactin resistance (PYR)/ PYR1-like (PYL)/Regulatory Component of Abscisic ...
Concatenated logic functions using nanofluidic diodes with all-electrical inputs and outputs

Gómez Lozano, Vicente; Ramirez Hoyos, Patricio; Cervera, Javier; Ali, Mubarak; Nasir, Saima; Ensinger, Wolfgang; Mafé, Salvador (Elsevier, 2018)

[EN] Nanopore-based logical schemes in ionic solutions typically involve single gates and chemical inputs. The design of computer-like functions requires the consecutive concatenation of several gates and the use of ...
FERONIA interacts with ABI2-type phosphatases to facilitate signaling cross-talk between abscisic acid and RALF peptide in Arabidopsis

Chen, Jia; Yu, Feng; Liu, Ying; Du, Changqing; Li, Xiushan; Zhu, Sirui; Wang, Xianchun; Lan, Wenzhi; Rodríguez Egea, Pedro Luís; Liu, Xuanming; Li, Dongping; Chen, Liangbi; Luan, Sheng (National Academy of Sciences, 2016-08-13)

[EN] Receptor-like kinase FERONIA (FER) plays a crucial role in plant response to small molecule hormones [e.g., auxin and abscisic acid (ABA)] and peptide signals [e.g., rapid alkalinization factor (RALF)]. It remains ...
How do plant viruses induce disease? Interactions and interference with host components

Pallás Benet, Vicente; Garcia, J.A (Society for General Microbiology, 2011)

[EN] Plant viruses are biotrophic pathogens that need living tissue for their multiplication and thus, in the infection-defence equilibrium, they do not normally cause plant death. In some instances virus infection may ...
IDENTIFICATION OF TARGETS AND AUXILIARY PROTEINS OF PYR/PYL/RCAR ABA RECEPTORS: PROTEIN PHOSPHATASES TYPE 2C (PP2Cs) AND C2-DOMAIN ABA-RELATED PROTEINS (CARs)

Rodríguez Solovey, Leisa Natacha (Universitat Politècnica de València, 2015-12-16)

[EN] ABSTRACT 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 ...
Logic Functions with Stimuli-Responsive Single Nanopores

Ramirez Hoyos, Patricio; Cervera Montesinos, Javier; Ali, Mubarak; Ensinger, Wolfgang; Mafé, Salvador (John Wiley & Sons, 2014)

[EN] We present the concept of logic functions based on a single stimuli-responsive nanopore and analyze its potential for electrochemical transducers and actuators. The responsive molecules at the surface of the polymeric ...
Perturbation of spermine synthase Gene Expression and Transcript Profiling Provide New Insights on the Role of the Tetraamine Spermine in Arabidopsis Defense against Pseudomonas viridiflava

Gonzalez, M.E.; Marco, F; Minguet, E.G.; Carrasco-Sorli, P.; Blazquez Rodriguez, Miguel Angel; Carbonell Gisbert, Juan; Ruiz, Oscar Adolfo; Pieckenstain, Fernando Luis (American Society of Plant Biologists, 2011-08)

[EN] The role of the tetraamine spermine in plant defense against pathogens was investigated by using the Arabidopsis (Arabidopsis thaliana)-Pseudomonas viridiflava pathosystem. The effects of perturbations of plant spermine ...
Role of surface chemistry in protein remodeling at the cell-material interface

Llopis Hernández, Virginia; Rico Tortosa, Patricia María; Ballester Beltrán, José; Moratal Pérez, David; Salmerón Sánchez, Manuel (Public Library of Science, 2011)

Background: The cell-material interaction is a complex bi-directional and dynamic process that mimics to a certain extent the natural interactions of cells with the extracellular matrix. Cells tend to adhere and rearrange ...
Structure-Based Modulation of the Ligand Sensitivity of a Tomato Dimeric Abscisic Acid Receptor Through a Glu to Asp Mutation in the Latch Loop

Infantes, Lourdes; Rivera-Moreno, Maria; Daniel-Mozo, Miguel; Benavente, Juan Luis; Ocaña-Cuesta, Javier; Coego, Alberto; Lozano Juste, Jorge; Rodríguez Egea, Pedro Luís; Albert, Armando (Frontiers Media SA, 2022-06-06)

[EN] The binding of the plant phytohormone Abscisic acid (ABA) to the family of ABA receptors (PYR/PYL/RCAR) triggers plant responses to abiotic stress. Thus, the implementation of genetic or chemical strategies to modulate ...
Terpene down-regulation triggers defense responses in transgenic oranges leading to resistance against fungal pathogens

Rodríguez, Ana; Shimada, Takehiko; Cervera, Magdalena; Alquézar, Berta; Gadea Vacas, José; Gómez-Cadenas, Aurelio; De Ollas, Carlos José; Rodrigo, María Jesús; Zacarías, Lorenzo; PEÑA GARCIA, LEANDRO (American Society of Plant Biologists, 2014-01)

Terpenoid volatiles are isoprene compounds that are emitted by plants to communicate with the environment. In addition to their function in repelling herbivores and attracting carnivorous predators in green tissues, the ...
