A permeable cuticle is associated with the release of reactive oxygen species and induction of innate immunity

L'Haridon, Floriane; Besson-Bard, Angelique; Binda, Matteo; Serrano Mateo, Mario; Abou-Mansour, Eliane; Balet, Francine; Schoonbeek, Henk-Jan; Hess, Stephane; Mir Moreno, Ricardo; Leon Ramos, Jose; Lamotte, Olivier; Metraux, Jean-Pierre (Public Library of Science, 2011)

[EN] Wounded leaves of Arabidopsis thaliana show transient immunity to Botrytis cinerea, the causal agent of grey mould. Using a fluorescent probe, histological staining and a luminol assay, we now show that reactive oxygen ...
Carnosic acid-rich rosemary (Rosmarinus officinalis L.) leaf extract limits weight gain and improves cholesterol levels and glycaemia in mice on a high-fat diet

Ibarra, Alvin; Cases, Julien; Roller, Marc; Chiralt, A.; Coussaert, Aurélie Coussaert; Ripoll, Christophe (Cambridge University Press, 2011)

Rosemary (Rosmarinus officinalis L.) extracts (RE) are natural antioxidants that are used in food, food supplements and cosmetic applications; exert anti-inflammatory and anti-hyperglycaemic effects; and promote weight ...
Evaluation of nonpolar metabolites in plant extracts by 13C NMR spectroscopy

Palomino-Schätzlein, Martina; Escrig Aparici, Pablo Vicente; Boira Tortajada, Herminio; Primo Millo, Jaime; Pineda-Lucena, Antonio; Cabedo Escrig, Nuria (American Chemical Society, 2011-10-09)

13C nuclear magnetic resonance (NMR) spectroscopy was explored as a simple and efficient technique for the quantitative analysis of nonpolar metabolites in plants. The method was first optimized with a mixture of known ...
Gibberellin A1 metabolism contributes to the control of photoperiod mediated tuberization in potato

Bou-Torrent, J; Martinez-Garcia, J.F; Garcia Martinez, Jose L; Prat, Salomé (Public Library of Science, 2011)

[EN] Some potato species require a short-day (SD) photoperiod for tuberization, a process that is negatively affected by gibberellins (GAs). Here we report the isolation of StGA3ox2, a gene encoding a GA 3-oxidase, whose ...
Isolation of a new Mexican strain of Bacillus subtilis with antifungal and antibacterial activities

Basurto Cadena, María Guadalupe Lucía; Vázquez Arista, Manuel; García Jiménez, José; Salcedo Hernandez, R.; Bideshi, D.K.; Barboza Corona, J.E. (Hindawi Publishing Corporation, 2012)

[EN] Although several strains of B. subtilis with antifungal activity have been isolated worldwide, to date there are no published reports regarding the isolation of a native B. subtilis strain from strawberry plants in ...
Photosynthesis down-regulation precedes carbohydrate accumulation under sink limitation in Citrus

González Nebauer, Sergio; Renau Morata, Begoña; Guardiola, Jose Luis; Molina Romero, Rosa Victoria (Oxford University Press (OUP), 2011-02)

Photosynthesis down-regulation due to an imbalance between sources and sinks in Citrus leaves could be mediated by excessive accumulation of carbohydrates. However, there is limited understanding of the physiological role ...
Physiological,anatomical and biomass partitioning responses to ozone in the Mediterranean endemic plant Lamottea dianae

Calatayud, V.; García Breijo, Francisco José; Cervero, J; Reig Armiñana, José; Sanz Sánchez, Maria Jose (Elsevier, 2011-07)

Ozone effects on the perennial forb Lamottea dianae were studied in an open-top chamber experiment. Ozone was found to induce reductions in CO 2 assimilation and water use efficiency in the leaves of this species. These ...
Responses of evergreen and deciduous Quercus species to enhanced ozone levels

Calatayud, V.; Cervero, J.; Calvo, E.; García Breijo, Francisco José; Reig Armiñana, José; Sanz, M.J. (Elsevier, 2011-01)

Plants of one evergreen oak (Quercus ilex) and three deciduous oaks (Q. faginea, with small leaves; Q. pyrenaica and Q. robur, with large leaves) were exposed both to filtered air and to enhanced ozone levels in Open-Top ...
Transcriptome characterization and high throughput SSRs and SNPs discovery in Cucurbita pepo (Cucurbitaceae)

Blanca Postigo, José Miguel; Cañizares Sales, Joaquín; Roig Montaner, Mª Cristina; Ziarsolo Areitioaurtena, Pello; Nuez Viñals, Fernando; Picó Sirvent, María Belén (BioMed Central, 2011)

Background: Cucurbita pepo belongs to the Cucurbitaceae family. The "Zucchini" types rank among the highest-valued vegetables worldwide, and other C. pepo and related Cucurbita spp., are food staples and rich sources of ...
