Kinetics of NH 4 + uptake by the arbuscular mycorrhizal fungus Rhizophagus irregularis
Pérez-Tienda, J.; Valderas, A.; Camañes, Gemma; García Agustín, Pilar; Ferrol, N. Springer-Verlag (2012-08)The kinetics and energetics of 15NH 4 + uptake by the extraradical mycelium of the arbuscular mycorrhizal fungus Rhizophagus irregularis were investigated. 15NH 4 + uptake increased with increasing substrate concentration ... -
NH4+ induces antioxidant cellular machinery and provides resistance to salt stress in citrus plants
Fernández Crespo, Emma; Gómez Pastor, Rocío; Scalschi, Loredana; Llorens, Eugenio; Camañes, Gemma; García Agustín, Pilar Springer Verlag (2014-09)NH4 + nutrition in Carrizo citrange (Citrus sinensis L. Osbeck × Poncirus trifoliata L) plants acts as an inducer of resistance against salinity conditions. NH4 + treatment triggers mild chronic stress that primes plant ... -
NH4+ protects tomato plants against Pseudomonas syringae by activation of systemic acquired acclimation
Fernández Crespo, Emma; Scalschi, Loredana; Llorens, Eugenio; García Agustín, Pilar; Camañes, Gemma Oxford University Press (2015-08)NH4 + nutrition provokes mild toxicity by enhancing H2O2 accumulation, which acts as a signal activating systemic acquired acclimation (SAA). Until now, induced resistance mechanisms in response to an abiotic stimulus and ... -
Priming by Hexanoic Acid Induce Activation of Mevalonic and Linolenic Pathways and Promotes the Emission of Plant Volatiles
Llorens, Eugenio; Camañes, Gemma; Lapeña, Leonor; García Agustín, Pilar Frontiers Media (2016-04-12)Hexanoic acid (Hx) is a short natural monocarboxylic acid present in some fruits and plants. Previous studies reported that soil drench application of this acid induces effective resistance in tomato plants against Botrytis ... -
Priming for JA-dependent defenses using hexanoic acid is an effective mechanism to protect Arabidopsis against B. cinerea
Kravchuk, Zhana; Vicedo, Begonya; Flors, Victor; Camañes, Gemma; González-Bosch, Carmen; García Agustín, Pilar Elsevier (2011)Soil drench treatments with hexanoic acid can effectively protect Arabidopsis plants against Botrytis cinerea through a mechanism based on a stronger and faster accumulation of JA-dependent defenses. Plants impaired in ... -
Putrescine Biosynthesis Inhibition in Tomato by DFMA and DFMO Treatment
Fernández Crespo, Emma; González-Hernández, Ana I.; Scalschi, Loredana; Llorens, Eugenio; García Agustín, Pilar; Camañes, Gemma Bio-protocol LLC (2016)This protocol can be used to inhibit the biosynthesis of polyamines, specifically putrescine, in tomato plants grown with NH4 + as a solely N source. In general, polyamines are positively charged small metabolites ... -
Putrescine biosynthetic pathways modulate root growth differently in tomato seedlings grown under different N sources
González-Hernández, Ana I.; Scalschi, Loredana; Troncho, Pilar; García Agustín, Pilar; Camañes, Gemma Elsevier (2021-11-16)The biosynthesis of putrescine is mainly driven by arginine decarboxylase (ADC) and ornithine decarboxylase (ODC). Hence, in this study, we generated independent ADC and ODC transgenic silenced tomato lines (SilADC and ... -
Quantification of Callose Deposition in Plant Leaves
Scalschi, Loredana; Llorens, Eugenio; Camañes, Gemma; Pastor, Victoria; Fernández Crespo, Emma; Flors, Victor; García Agustín, Pilar; Vicedo, Begonya Bio-protocol LLC (2015-10)Callose is an amorphous homopolymer, composed of β-1, 3-glucan, which is widespread in higher plants. Callose is involved in multiple aspects of plant growth and development. It is synthetized in plants at the cell plate ... -
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 ... -
Resistance Inducers Modulate Pseudomonas syringae pv. Tomato Strain DC3000 Response in Tomato Plants
Scalschi, Loredana; Camañes, Gemma; Llorens, Eugenio; Fernández Crespo, Emma; López, María M.; García Agustín, Pilar; Vicedo, Begonya Public Library of Science (2014)The efficacy of hexanoic acid (Hx) as an inducer of resistance in tomato plants against Pseudomonas syringae pv. tomato DC3000 was previously demonstrated, and the plant response was characterized. Because little is known ... -
Response of tomato-pseudomonas pathosystem to mild heat stress
Scalschi, Loredana; Fernández-Crespo, Emma; Pitarch Marín, Marcel; Llorens, Eugenio; González-Hernández, Ana I.; Camañes, Gemma; Vicedo, Begonya; García Agustín, Pilar (2022)Higher plants suffer from mild heat stress when temperatures increase by 5 ◦C above optimum growth temperatures. This produces changes at the cellular and metabolic levels, allowing plants to adapt to heat conditions. ... -
Silencing of OPR3 in tomato reveals the role of OPDA in callose deposition during the activation of defense responses against Botrytis cinerea
Scalschi, Loredana; Sanmartín, Maite; Camañes, Gemma; Troncho, Pilar; Sánchez-Serrano, José J.; García Agustín, Pilar; Vicedo, Begonya Wiley (2015)Cis-(+)-12-oxo-phytodienoic acid (OPDA) is likely to play signaling roles in plant defense that do not depend on its further conversion to the phytohormone jasmonic acid. To elucidate the role of OPDA in Solanum lycopersicum ... -
The nitrogen availability interferes with mycorrhiza-induced resistance against botrytis cinerea in tomato
Sánchez-Bel, Paloma; Troncho, Pilar; Gamir, Jordi; Pozo, Maria J.; Camañes, Gemma; Cerezo García, Miguel; Flors, Victor Frontiers Media (2016)Mycorrhizal plants are generally quite efficient in coping with environmental challenges.
