A deletion in NRT2.1 attenuates pseudomonas syringae-induced hormonal perturbation, resulting in primed plant defenses
Camañes, Gemma; Flors, Victor; García Agustín, Pilar; Cerezo García, Miguel; Vicedo, Begonya; Pastor, Victoria; García-Andrade, Javier American Society of Plant Biologists (2012)For an efficient defense response against pathogens, plants must coordinate rapid genetic reprogramming to produce an incompatible interaction. Nitrate Trasnporter2 (NRT2) gene family members are sentinels of nitrate ... -

Precursor ... -
Disruption of the ammonium transporter AMT1.1 alters basal defenses generating resistance against Pseudomonas syringae and Plectosphaerella cucumerina
Pastor, Victoria; Gamir, Jordi; Camañes, Gemma; Cerezo García, Miguel; Sánchez-Bel, Paloma Frontiers (2014)Disruption of the high-affinity nitrate transporter NRT2.1 activates the priming defense against Pseudomonas syringae, resulting in enhanced resistance. In this study, it is demonstrated that the high-affinity ammonium ... -
Fine Tuning of Reactive Oxygen Species Homeostasis Regulates Primed Immune Responses in Arabidopsis
Pastor, Victoria; Luna Diez, Estrella; Ton, Jurriaan; Cerezo García, Miguel; García Agustín, Pilar; Flors, Victor The American Phytopathological Society (2013-11)Selected stimuli can prime th e plant immune system for a faster and stronger defense reaction to pathogen attack. Pretreatment of Arabidopsis with the chemical agent β - aminobutyric acid (BABA) augmented ... -
Identification of indole-3-carboxylic acid as mediator of priming against Plectosphaerella cucumerina
Gamir, Jordi; Pastor, Victoria; Cerezo García, Miguel; Flors, Victor Elsevier (2012)Plant resistance against the necrotrophic pathogen Plectosphaerella cucumerina is mediated by a combination of several hormonal-controlled signalling pathways. The priming agent β-aminobutyric acid (BABA) is able to induce ... -
Mycorrhiza l tomato plants fine tunes the growth‐defencebalance upon N depleted root environments
Sánchez-Bel, Paloma; Sanmartín, Neus; Pastor, Victoria; Mateu Garcia, Diego; Cerezo García, Miguel; Vidal-Albalat, Andreu; Pastor Fernández, Julia; Pozo, Maria J.; Flors, Victor Wiley (2018)In low nutritive environments, the uptake of N by arbuscular mycorrhizal (AM) fungi may confercompetitive advantages for the host. The present study aims to understand how mycorrhizaltomato plants perceive and then prepare ... -
New insights into the role of indole-3-acetic acid in the virulence of Pseudomonas savastanoi pv. savastanoi
Aragón, Isabel M.; Pérez-Martínez, Isabel; Moreno-Pérez, Alba; Cerezo García, Miguel; Ramos, Cayo Wiley Online Library (2014)Indole-3-acetic acid (IAA) is a widespread phytohormone among plant-associated bacteria, including the tumour-inducing pathogen of woody hosts, Pseudomonas savastanoi pv. savastanoi. A phylogenetic analysis of the iaaM/iaaH ... -
Reciprocal regulation between AtNRT2.1 and AtAMT1.1 expression and the kinetics of NH4+ and NO3− influxes
Camañes, Gemma; Bellmunt, Elena; García-Andrade, Javier; García Agustín, Pilar; Cerezo García, Miguel Elsevier (2012)Our results show that AtNRT2.1 expression has a positive effect on the NH4+ ion influx, mediated by the HATS, as also occurs with AtAMT1.1 expression on the NO3− ion influx. AtNRT2.1 expression plays a key role in the ... -
