Role of 9-Lipoxygenase and α-Dioxygenase Oxylipin Pathways as Modulators of Local and Systemic Defense
Oxford University Press (2012)Plant 9-lipoxygenases (9-LOX) and α-dioxygenases (α-DOX) initiate the synthesis of oxylipins after bacterial infection. Here, the role of these enzymes in plants’ defense was investigated using individual Arabidopsis ... -
Does host adaptation of Tetranychus urticae populations in clementine orchards with a Festuca arundinacea cover contribute to a better natural regulation of this pest mite?
Wiley-Blackwell (2012)Tetranychus urticae Koch (Acari: Tetranychidae) is a key pest of clementine mandarins, Citrus clementina Tanaka (Rutaceae), in Spain. This mite is highly polyphagous and can be easily found in clementine orchards, both in ... -
Assesment of PM10 pollution episodes in a ceramic cluster (NE Spain): Proposal of a new quality index for PM10, As, Cd, Ni and Pb
Elsevier (2012)Environmental pollution control is one of the most important goals in pollution risk assessment today. In this sense, modern and precise tools that allow scientists to evaluate, quantify and predict air pollution are of ... -
Influence of Exogenous Glycine Betaine and Abscisic Acid on Papaya in Responses to Water-deficit Stress
Springer-Verlag (2012)The effects of exogenous foliar glycine betaine (GB) and abscisic acid (ABA) on papaya responses to water stress were investigated under distinct water regimes. Papaya seedlings (Carica papaya L. cultivar “BH-65”) were ... -
A Fast and Precise Method To Identify Indolic Glucosinolates and Camalexin in Plants by Combining Mass Spectrometric and Biological Information
American Chemical Society (2012)In this manuscript, a fast and accurate identification and quantitation by mass spectrometry of indolic glucosinolates and camalexin involved in defense in Arabidopsis thaliana are described. Two elicitation systems, ... -
A deletion in the nitrate high affinity transporter NRT2.1 alters metabolomic and transcriptomic responses to Pseudomonas syringae
Landes Bioscience (2012)A deletion in the high affinity nitrate trasporter NRT2.1 in Arabidopsis results in a reduced susceptibility to Pseudomonas syringae by two different mechanisms, the SA priming and an interference in the effector triggered ... -
Air pollution prediction models of particles, As, Cd, Ni and Pb in a highly industrialized area in Castellón (NE, Spain)
Springer-Verlag (2012)The objective of this study was to elaborate a series of mathematical models with the aim of short-term prediction of TSP, PM10, As, Cd, Ni and Pb in ambient air. These pollutants depend on some known variables (meteorological ... -
Delimitation of the Coastal Transition Zone in the Gulf of Guayaquil, Ecuador
Canadian Center of Science and Education (2012)The article presents a methodology for the delimitation of the coastal transition zone (CTZ) and the identification of zones with distinct soil properties in the Gulf of Guayaquil (GG), Ecuador. The Gulf was chosen as ... -
Kinetic analysis for macrocyclizations involving anionic template at the transition state
Hindawi Publishing Corporation (2012)Several kinetic models for the macrocyclization of a C 2 pseudopeptide with a dihalide through a S N 2 ... -
A deletion in NRT2.1 attenuates pseudomonas syringae-induced hormonal perturbation, resulting in primed plant defenses
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 ... -
T3SS-dependent differential modulations of the jasmonic acid pathway in susceptible and resistant genotypes of Malus spp. challenged with Erwinia amylovora
Elsevier (2012)Fire blight is a bacterial disease of Maloideae caused by Erwinia amylovora (Ea). This necrogenic enterobacterium uses a type III secretion system (T3SS) to inject type III effectors into the plant cells to cause disease ... -
Influence of organic matter transformations on the biovailability of heavy metals in a sludge based compost
Elsevier (2012)The agricultural use of anaerobically digested sewage sludge (ADSS) as stable, mature compost implies knowing its total content in heavy metals and their bioavailability. This depends not only on the initial characteristics ... -
Reciprocal regulation between AtNRT2.1 and AtAMT1.1 expression and the kinetics of NH4+ and NO3− influxes
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 ... -
Descendants of primed arabidopsis plants exhibit resistance to biotic stress
American Society of Plant Biologists (2012)An attack of plants by pathogens or treatment with certain resistance-inducing compounds can lead to the establishment of a unique primed state of defense. Primed plants show enhanced defense reactions upon further challenge ... -
Identification of indole-3-carboxylic acid as mediator of priming against Plectosphaerella cucumerina
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 ... -
Comparative analysis of transcriptomic and hormonal responses to compatible and incompatible plant-virus interactions that lead to cell death
American Phytopathological Society (2012)Hypersensitive response-related programmed cell death (PCD) has been extensively analyzed in various plant-virus interactions. However, little is known about the changes in gene expression and phytohormone levels associated ... -
