La condició sèssil de les plantes ha fet que desenvolupin un ampli ventall de defenses físiques i químiques per fer front a herbívors i patògens. Moltes plantes tenen reserves permanents de productes químics (defenses constitutives) per fer front a les agressions biòtiques immediatament, però aquestes defenses també poden augmentar o canviar proporcionalment davant d'un atac (defenses induïdes). [...] Plants, due to their sessile condition, have developed a plethora of physical and chemical defences to make front to herbivores and pathogens. Chemical defences are very versatile: permanent reserves of chemical compounds (constitutive defences) are useful to face aggressions immediately, but these defences can also increase or change when biotic aggressions are detected (induced defences).

La presente tesis doctoral se ha centrado en el estudio de la variabilidad del DNA mitocondrial (DNAmt) por secuenciación masiva (NGS) y el impacto de dicha variabilidad en el glioma cerebral. Debido al papel que desempeña la mitocondria en la producción de energía celular, se ha postulado que alteraciones en el DNAmt pueden contribuir al proceso carcinogénico, sobre todo en aquellos tejidos que requieren más energía, como el cerebral. [...] This PhD thesis was focused on the studying of the variability of mitochondrial DNA (DNAmt) by massive parallel sequencing (NGS) and the impact of such variability on the glioma. Due to the significant role of mitochondria in cellular energy production, it has been postulated that mtDNA alterations might contribute to the carcinogenesis process, particularly in those tissues that require more energy, such as the brain.

A pesar del declive generalizado de las abejas debido a la pérdida de sus hábitats y la transformación del paisaje, algunas especies de abejas pueden adaptarse para vivir en habitats modificados por el hombre. [...] Despite bees are in general declining due to habitat loss and transformation, some bee species can adapt to live in human transformed habitats. Precisely, we lack information on the mechanisms that allow them to survive in transformed habitats. [...]

En esta tesis doctoral se han estudiado diversos aspectos biológicos importantes sobre la enfermedad de la mancha ocre del almendro (RLB, por sus siglas en ingles), causada por el hongo ascomiceto P. [...] Major biological aspects of the red leaf blotch (RLB) disease of almond, caused by the ascomycete Polystigma amygdalinum, were studied in this PhD Thesis. This disease is one of the most important foliar diseases in most almond-growing regions in the Mediterranean basin and the Middle East, since severe infections may cause a premature defoliation of the tree.

Introduction: This thesis was devoted to the study of the foot, mainly in ancient collections. The foot is a forgotten bone set in many anthropological, paleopathological, and forensic studies. However, being the key structure that maintains the upright position, it is basic to know the life of a specific individual and the destiny of a population. [...]

Un sistema sexual és defineix com el patró de distribució de la funció masculina i femenina que existeix en una espècie donada, que pot tenir lloc en individus separats (gonocorisme) o al mateix individu (hermafroditisme). [...] A sexual system defines the pattern of distribution of male and female function that exists in a given species, which can occur in separate individuals (gonochorism) or in the same individual (hermaphroditism).

En la mayoría de los organismos estudiados, el reloj circadiano mantiene ritmos en fisiología, metabolismo y desarrollo en sintonía con los cambios medioambientales que suceden durante los ciclos diurnos y nocturnos. [...] In most organisms examined to date, the circadian clock sustains rhythms in physiology, metabolism and development in tune with the environmental changes that occur during the day and night cycle. In plants, the circadian clock controls the proper timing of many essential processes including among others plant responses to a number of abiotic and biotic stresses. [...]

La maduixa representa el cultiu de baies més consumit a tot el món, amb una producció de 9,2 milions de tones l'any 2017. Els programes de millora tradicionalment s'han centrat en els trets agronòmics, però la qualitat dels fruits s'ha convertit recentment en un objectiu principal. [...] La fresa representa el cultivo de bayas más consumido en todo el mundo, con una producción de 9,2 millones de toneladas en el año 2017. Los programas de mejora se han centrado en caracteres agronómicos, siendo la calidad del fruto un objetivo principal en los últimos años. [...] Strawberry, belonging to Fragaria genus, Rosaceae family, is the most commonly consumed berry fruit crop worldwide, with a production of around 9. 2 million tons during 2017. Although traditionally breeding programs have been focused on improving agronomic traits, fruit quality has become a main goal recently. [...]
