  2. Estudio de la Función de las Giberelinas en la Determinación del Número de Óvulos en Plantas

    BARRO TRASTOY, DANIELA
    La formación de óvulos y semillas es un proceso esencial para las plantas, ya que asegura su correcta reproducción, y para el ser humano, pues tiene una gran importancia económica al repercutir directamente en el rendimiento de muchos cultivos. La formación de óvulos se trata, además, de un proceso de desarrollo complejo en el que participan varias redes génicas y hormonales. Actualmente se conocen algunos de los genes clave implicados en el control de la iniciación y desarrollo de los óvulos en Arabidopsis thaliana. Entre los componentes genéticos más relevantes se encuentran AINTEGUMENTA (ANT) y CUP-SHAPE COTYLEDON1 y 2 (CUC1...

  3. Caracterización funcional de un nuevo regulador genético del crecimiento radial de las plantas

    CHANZÁ MARTORELL, AMPARO GEMA
    [EN] The growth of the microorganism is remarked by the integration and coordination of different types of development. In plants, the secondary growth represents the radial growth of the roots and stems in thickness. This process is very important because contributes to the mechanical support and stability for a good length growth and properly maintain their organs. In addition, the secondary growth is the source of a huge amount of biomass that is the origin of the wood of the trees. Even it is so important it is unknown its genetic and molecular regulation. In our Lab a previous experiment was...

    FORTÚN CHOCARRO, MARÍA TERESA
    Las raíces dan capacidad de anclaje a la planta y son los órganos esenciales para explorar y explotar los recursos del suelo. El creciente interés por manipular el desarrollo radicular emana de los retos a los que tendrá que enfrentarse la agricultura en los próximos años: suelos con menores recursos de agua y nutrientes. Se ha propuesto que el desarrollo de nuevos cultivares con sistemas radiculares más eficientes para la adquisición de agua en condiciones de estrés hídrico podría tener un impacto significativo en la producción alimentaria mundial, pero este objetivo sólo podrá lograrse sobre la base del conocimiento de...

  5. Análisis de la heredabilidad de los mecanismos de respuesta a estrés relacionados con la regulación epigenética de la expresión génica

    LEGIDO PEÑA, SERGIO
    [EN] Continuously organisms are persistently exposed to different elements that compromise their survival. In this context, the plants, as sessile organisms, are especially vulnerable. Nevertheless, during the evolution, plants have developed mechanisms that allow to maintain their cellular homeostasis while maintaining a relative plasticity under exposition to different stresses. Between the different phytopathogens there are the viroids, whose vital cycle is tightly linked to their host. Recently, studies carried out with “Hop Stunt Viroid” point to a new mechanism that include the interference of the epigenetic host pattern Cucumis sativus. Surprisingly, it has been proven that this modification also affects the germinal line of male plants, affecting their gametophyte: the...

  6. Identificación y caracterización de mutantes afectados en el desarrollo foliar en líneas T-DNA de tomate

    ROMERO CORTÉS, PABLO YUSSEF
    Detection of mutants with some alteration in leaf development is the best strategy to identify the genes that control these characters. Among the possible alternatives to generate mutants (e.g., radiations, chemical products such as EMS, etc.), insertional mutagenesis is the most appropriate to address this objective. With this strategy, after obtaining a large number of transgenic plants, their phenotype is evaluated in order to detect alterations caused by the integration of T-DNA. If the disruption of an endogenous gene occurs, a loss-of-function mutant is usually obtained, whereas the insertion of the T-DNA in a control region or in the vicinity...

  7. Busqueda de Agroquimicos y edicion de genomas para aumentar la resistencia de las plantas a la sequía

    GARCÍA MAQUILÓN, IRENE
    Drought is one of the most important causes of productivity loss in crops worldwide. For this reason it is of great importance to study the processes of adaptation and tolerance of plants to water stress, especially in plants with agronomic interest. Abscisic acid (ABA) regulates development and stress responses in plants, playing a fundamental role in the adaptation to water stress conditions. In order to improve drought tolerance in economically important crops, we have carried out a project aimed to identify ABA agonists and to implement genome editing techniques in the C4 model plant Setaria viridis. In this work, we...

  8. Control hormonal del desarrollo de los óvulos de tomate: Papel de las giberelinas y su interacción con los brasinosteroides y las citoquininas

    FREIXAS CARDONA, JOAN
    There are many factors that regulated the development of the ovules in plants. Different hormones, which have a fundamental role, participate in the control of this process. In the model plant Arabidopsis thaliana, the role of the auxin hormones (AUX), brassinosteroids (BRs) and cytokinins (CKs) has been determined and the interactions between these hormones have been suggested at the beginning of ovules formation, as well as during the development phase. The gibberellins (GAs) control various processes of plant development; however, their participation in ovules formation has recently been suggested by studies carried out in our laboratory showed that the mutations...

  9. Caracterización de enzimas peroxidasas involucradas en la formación de la cubierta de la semillas en Arabidopsis

    BARBERÁ MORENO, SAMUEL
    [EN] Seed longevity is a crucial factor in agriculture because seeds lose their viability during long-term storage. So, farmers need to buy new seeds every year. The reduction of the crop yield associated with an increase of expenses makes seed longevity an important trait for agricultural economy. Thus, the identification of genes involved in seed longevity constitutes a new target in breeding programs. The purpose of this project is to characterize peroxidases involved in the Arabidopsis thaliana’s seed coat formation and seed longevity. Peroxidases might play an important role for the polymerization of suberin in the outer integument of the seed coat. To identify what peroxidases are involved...

    ABARCA LÁZARO, JAVIER
    The prospects of treatment for neurodegenerative diseases require tackling the issue that the blood-brain barrier signifies for the appropriate drug delivery towards the central nervous system. Through the last decades numerous approaches have been considered to overcome this barrier and the research goes on, searching for new, more effective strategies that manage not only to deliver the drug to its molecular target but to ensure a proper distribution and dosage, reducing the potential risks for the patient. In our experimental assay we explore three protocols to achieve the production of poly-lactic-co-glycolic acid (PLGA), poly-L-lactic acid (PLLA) and chitosan microparticles, biopolymers...

  11. Valoración de la fiabilidad de los resultados de calibrado de una cámara conociendo sus parámetros extrínsecos.

    DÍAZ IZA, HAROLD JOSÉ
    In general, validation of a camera calibration process is based on the reprojection error calculated with the computed model. Given the coupling that exists between several parameters of the camera model, this error can be zero even if the computed camera model does not represent it. In this work a validation of which camera calibration methods obtain better results is done, from the point of view of knowing which model bettrer represents the camera intrinsic parameters and the conditions under which the calibration process is being performed.

  13. Estrategias de ubicación de procesos en núcleos para Sistemas de Tiempo Real "Soft" con multinúcleos SMT

    Furió Novejarque, Clara
    [EN] Real-time systems support a high variety of applications with hard real-time (HRT) constraints or soft (i.e. non-strict) real-time (SRT) constraints. Systems observing HRT constraints must guarantee execution time bounds for tasks with mandatory deadlines and usually do not require from complex processors. In contrast, applications with relaxed time constraints do not cause a system failure when missing a deadline, which just affects their quality of service. Examples of SRT applications are video encoding and decoding, which are becoming ubiquitous in our lifes. Unlike HRT applications, the computational requirements of SRT applications requires from complex microarchitectural techniques such as Simultaneous Multithreading...
