A meta-analysis reveals the commonalities and differences in Arabidopsis thaliana response to different viral pathogens

Rodrigo Tarrega, Guillermo; Carrera Montesinos, Javier; Ruiz-Ferrer, Virginia; Del Toro, F.J.; Llave, C; Voinnet, O.; Elena Fito, Santiago Fco (Public Library of Science, 2012-07)

Understanding the mechanisms by which plants trigger host defenses in response to viruses has been a challenging problem owing to the multiplicity of factors and complexity of interactions involved. The advent of genomic ...
Aerobic Hydrogen Production via Nitrogenase in Azotobacter vinelandii CA6

Noar, Jesse; Loveless, Telisa; Navarro Herrero, José Luís; Olson, Jonathan W.; Bruno-Barcena, Jose M. (American Society for Microbiology, 2015-07)

The diazotroph Azotobacter vinelandii possesses three distinct nitrogenase isoenzymes, all of which produce molecular hydrogen as a by-product. In batch cultures, A. vinelandii strain CA6, a mutant of strain CA, displays ...
Coordinated gene regulation in the initial phase of salt stress adaptation

Vanacloig Pedros, Mª ELENA; Bets Plasencia, Carolina; Pascual-Ahuir Giner, María Desamparados; Proft, Markus Hans (American Society for Biochemistry and Molecular Biology, 2015-04-17)

[EN] Stress triggers complex transcriptional responses, which include both gene activation and repression. We used time-resolved reporter assays in living yeast cells to gain insights into the coordination of positive and ...
DNA-binding specificities of plant transcription factors and its potential to define target genes

Franco-Zorrilla, Jose Manuel; López-Vidriero, Irene; Carrasco Jiménez, José Luis; Godoy, Marta; Vera Vera, Pablo; Solano, Roberto (National Academy of Sciences, 2014-02-11)

[EN] Transcription factors (TFs) regulate gene expression through binding to cis-regulatory specific sequences in the promoters of their target genes. In contrast to the genetic code, the transcriptional regulatory code ...
Estudio de la regulación transcripcional del promotor de la proteína metalotioneína de tipo 2B mediante el sistema CRISPR/Cas9 en Nicotiana benthamiana

Ajenjo Bauzá, María (Universitat Politècnica de València, 2018-09-14)

[EN] The discovery of CRISPR/Cas system has meant a revolution in the synthetic biology field. Among all its applications, it could be found the genomic engineering or programmable transcriptional modulation. In this work, ...
Estudio del papel del oncogén MYCN como factor de transcripción en la regulación del promotor del gen IDH2

Vicente Herráiz, María (Universitat Politècnica de València, 2019-09-30)

[ES] El neuroblastoma es el tumor sólido extracraneal más habitual en niños, formándose en las células primordiales de la cresta neural. La mayoría de los neuroblastomas son formas esporádicas y sólo en el 1-2 % de los ...
Evolución de la regulación transcripcional por luz y temperatura en plantas

Rodríguez Marín, Fernando (Universitat Politècnica de València, 2022-03-31)

[ES] Las plantas terrestres evolucionaron de las algas carófitas hace en torno a 580 millones de años. Por esta razón, estas algas y las plantas terrestres comparten ciertas características que pudieron ser importantes ...
Evolution of DELLA proteins as transcriptional hubs in plants

Briones Moreno, Asier (Universitat Politècnica de València, 2021-01-17)

[ES] Las proteínas DELLA son elementos centrales de la ruta de señalización por giberelinas (GAs), donde actúan como represores de las respuestas a GAs. En angiospermas, se ha observado que las DELLAs interaccionan con ...
Evolutionary Analysis of DELLA-Associated Transcriptional Networks

Briones-Moreno, Asier; Hernández-García, Jorge; Vargas-Chávez, C.; Romero-Campero FJ; Romero, J.M.; Valverde, F.; Blazquez Rodriguez, Miguel Angel (Frontiers Media SA, 2017)

[EN] DELLA proteins are transcriptional regulators present in all land plants which have been shown to modulate the activity of over 100 transcription factors in Arabidopsis, involved in multiple physiological and developmental ...
Expression of the Intracellular COPT3-Mediated Cu Transport Is Temporally Regulated by the TCP16 Transcription Factor

Andrés-Colás, Nuria; Carrió-Seguí, Ángela; Abdel-Ghany, Salah E.; Pilon, Marinus; Peñarrubia, Lola (Frontiers Media SA, 2018-07-03)

[EN] Copper is an essential element in plants. When scarce, copper is acquired from extracellular environment or remobilized from intracellular sites, through members of the high affinity copper transporters family COPT ...
Gene regulation in climacteric fruit ripening

Brumos, Javier (Elsevier, 2021-10)

[EN] Seed dispersion and consequent plant propagation depend on the success of fruit ripening. Thus, ripening is a highly regulated developmental process aiming to maximize fruit organoleptic traits to attract herbivores. ...
Genetic redundancies enhance information transfer in noisy regulatory circuits

Rodrigo Tarrega, Guillermo; Poyatos, Juan F. (Public Library of Science, 2016-10)

[EN] Cellular decision making is based on regulatory circuits that associate signal thresholds to specific physiological actions. This transmission of information is subjected to molecular noise what can decrease its ...
