Arabidopsis thaliana is able to sense tomato Systemin promoting defense against fungal pathogens

Pòster presentat al Symposium on Small Molecules in Plant Research: Chemistry and Biology Come Together (Valencia, Spain, 10-11 December 2019).Systemin is a small tomato peptide that regulates the plant response against herbivores and pathogenic fungi. It is released from a larger precursor upon wounding or pathogen attack and binds to a membrane receptor of the adjacent cell inducing a cascade of plant defences, including JA-related responses, that lead to the accumulation of protease inhibitors in local and systemic tissue. Although the tomato Systemin has been the focus of many recent studies, very little is known about the perception and function of Systemin in heterologous species

Determinación voltamperométrica de ácido ascóbico en vinos

El incremento en el consumo del vino a nivel mundial ha dado lugar a que en los últimos años haya un interés creciente por mejorar su calidad. La decisión de incorporar antioxidantes en los vinos va a influir en gran medida en su composición final. El ácido ascórbico es un antioxidante natural que se encuentra en gran cantidad de productos. En el vino lleva a cabo una acción antioxidante eficaz, y su determinación se ha convertido en objeto de interés para las etapas de producción y control de calidad de las bebidas y alimentos. En esta revisión bibliográfica se presenta una descripción general de la importancia y mecanismo de acción del ácido ascórbico, así como las técnicas analíticas para su cuantificación en distintas bebidas. Se investiga el desarrollo de nuevos métodos voltamperométricos para su determinación en el vino, los cuáles recientemente se han convertido en una alternativa eficaz debido a que son métodos rápidos, simples y económicos.Máster en Calidad, Desarrollo e Innovación de Alimento

Turkey: macro-financial situation

Rationale. Turkey is identified annually as a material country for the Spanish and euro area banking systems. Moreover, Turkey and Spain are linked by major trade and financial flows. It is therefore important to monitor the country’s macro-financial situation and main weaknesses. Takeaways. • The Turkish economy continued to post very high inflation rates at end-2022, while economic activity began to slow in Q3, following its strong previous momentum. All of this in the context of sizeable external financing needs, foreign currency debt and low international reserves. • Fiscal policy performed better than expected, and the country’s accounts remain healthy. In terms of monetary policy, in August the Turkish central bank resumed the process of reducing the policy interest rate initiated a year earlier, with the real interest rate standing at -75.5% in November. • Nonetheless, macroprudential and regulatory measures were implemented to keep credit growth in check and encourage only lending to certain productive sectors. Meanwhile, the banking sector’s balance sheets remain relatively healthy, although some indicators have worsened

Turkey: macro-financial situation

Artículo de revistaIn 2021, the Turkish economy continued to be highly influenced by the course of the COVID-19 pandemic. Turkey has been more dynamic than other emerging economies since the start of the pandemic, but faces a number of macro-financial challenges as a result of imbalances that have become more acute during the crisis. These include, notably, high and persistent inflation, sizeable external financing needs (non-financial corporations have high levels of foreign currency-denominated debt), low international foreign currency reserves and growing bank deposit dollarisation. The banking sector remains relatively sound and its NPL ratio has declined, although some of its other indicators, such as profitability and solvency ratios, have slightly worsened

Efeitos do solo e clima numa vinha de uva de mesa com cultura de cobertura. Gestão da rega utilizando redes de sensores

[ENG] TThe use of mulches in vineyards and orchards is a traditional agricultural practice used with the aim of saving moisture, reducing weed growth and improving organic matter content in the soil. In table grape vineyards trained to overhead system in Puglia region (Southeastern Italy), plastic sheets covering the canopy are often used to either advance ripening or delay harvest. In this environment, the living mulches could contribute to the modification of the microclimate around the canopy below the plastic sheets. This condition has an influence on the climatic demand and on both the vegetative and productive activities, mainly in stages with a high evapotranspiration. However, the presence of living mulches could increase the demand of available water and nutrient resources and this could cause a lower yield. The aim of this study was to acquire a suitable knowledge to manage irrigation and verify the influences of living mulches on the vine by using wireless sensor networks to measure the vapor pressure deficit, soil water potential and content.[POR] A utilização de coberturas do solo em vinhas e pomares é uma prática agrícola tradicional, utilizada com o objetivo de preservar a humidade do solo, reduzir o crescimento de infestantes e melhorar o teor de matéria orgânica no solo. Em vinhas de uva de mesa, conduzidas em sistema de pérgula na região de Puglia (sudeste da Itália), são frequentemente usadas coberturas de plástico para promover o avanço da maturação ou o atraso da colheita. Neste ambiente a utilização de enrelvamentos pode contribuir para a modificação do microclima do copado. Esta condição pode influenciar a demanda atmosférica, bem como a atividade vegetativa e reprodutiva da videira, principalmente em períodos de elevada evapotranspiração. No entanto, a presença do enrelvamento pode originar um aumento da demanda dos recursos disponíveis, nomeadamente água e nutrientes, o que poderá provocar uma quebra de produção. O objetivo deste estudo foi adquirir conhecimento para a gestão da rega e, simultaneamente, verificar a influência dos enrelvamentos na atividade da videira, usando para o efeito redes de sensores “sem fio” para medir o déficit de pressão de vapor, o potencial e o conteúdo de água no solo.The development of this work was supported by: The Spanish Ministry of Science and Innovation through the project RIDEFRUT (ref.

El periodisme en el context de la cultura participativa

La creciente gama de herramientas y servicios en línea que posibilitan nuevas formas de comunicación favorece el crecimiento de las demandas de interactividad de los públicos. Eso hace que los medios de comunicación deban operar cada vez más en un contexto de cultura colaborativa. Ante esta realidad, algunos productores de medios fomentarán la participación de sus públicos y aprovecharán los contenidos generados por los usuarios, mientras que otros adoptarán una postura resistente. Se prevé que la mayoría de medios de comunicación intentarán encontrar una posición estable entre los dos extremos, tratando de establecer una nueva relación con sus públicos. Este artículo puede leerse como un diálogo en el que, por una parte, se explicita con ejemplos concretos que la tendencia a la creación de verdaderas comunidades participativas de creación de contenidos es imparable y, por la otra, se exponen una serie de reflexiones desde la teoría del periodismo sobre cómo puede gestionarse la demanda de interactividad y el impulso participativo de los públicos
