    Potencialidades del frijol caupí para la resiliencia al cambio climático en sistemas agrícolas locales
    (2022) Santana-Baños, Yoerlandy; González García, Esther; Ariz Arnedo, Idoia; Carrodeguas Díaz, Sergio; Ciencias; Zientziak
    Las evidencias científicas sugieren tres usos fundamentales del frijol caupí, con agro-ecológicas y beneficios productivos, sociales y ambientales en los sistemas agrícolas locales; sin embargo, su rendimiento a nivel mundial y en América no experimenta crecimiento en los últimos años. Los resultados obtenidos en Pinar del Río, Cuba, sugieren la posibilidad de emplearlo como alternativa para la producción de grano pero debe fomentarse, desde la ciencia, la innovación y las instituciones y órganos de decisión a nivel local, la cultura de producción y consumo de esta leguminosa para su aprovechamiento en la sostenibilidad agrícola de los agro-ecosistemas.

    iNaturalist Arga: acercándonos a la biodiversidad de los ríos urbanos para aprender a cuidarlos
    (Fundación Conama, 2021) González García, Esther; Peralta de Andrés, Francisco Javier; García, Mar; Alzueta, José; Fernández Escalada, Manuel; Marzo Pérez, Asier; Aliende, Andrea; Miguel, Jon; Alvira Guallart, María Aránzazu; Ciencias; Zientziak; Gobierno de Navarra / Nafarroako Gobernua, CENEDUCA3-2019
    La biodiversidad es un concepto que forma parte del currículo de la educación secundaria. Las herramientas TIC (Tecnologías de la Información y la Comunicación) colaborativas abiertas disponibles ofrecen nuevas posibilidades para el ampliar el conocimiento sobre biodiversidad de los estudiantes de secundaria y futuros ciudadanos. Este estudio utiliza la plataforma de ciencia ciudadana iNaturalist como herramienta de utilidad en el currículo sobre biodiversidad incluido en la educación secundaria obligatoria. En este contexto, se ha creado un proyecto en esta plataforma centrado en el río Arga que atraviesa la ciudad de Pamplona: https://www.inaturalist.org/projects/arga. El proyecto implica a centros de educación secundaria, formación profesional y educación ambiental para realizar observaciones sobre biodiversidad en el entorno dicho río. Su objetivo es mejorar el conocimiento de los estudiantes de educación secundaria del concepto biodiversidad así como del río, además de poner en valor este ecosistema fluvial en un entorno urbano en las futuras generaciones. El proyecto fue puesto en marcha en el curso 2019-2020 e incorpora 468 observaciones de 213 especies aportadas por 39 observadores y 140 identificadores han colaborado en su validación. Aunque la participación en ese curso fue limitada a un centro educativo como consecuencia de la pandemia COVID, esta experiencia ha servido como modelo para el futuro desarrollo del proyecto. En el curso 2020-2021 se vuelve a poner en marcha el proyecto ARGA con el objetivo de establecerse como una herramienta de referencia para la comunidad educativa y de conectar el sector educativo con la sociedad en torno al concepto biodiversidad para destacar su importancia en la calidad ambiental en medios urbanos.

    Drought stress tolerance in plants
    (MDPI, 2023) González García, Esther; Ciencias; Zientziak; Institute for Multidisciplinary Research in Applied Biology - IMAB
    The current climate change scenario is accelerating degradation, desertification, and salinisation: all destructive processes that are negatively impacting arable lands and food production. This is particularly important when considering how the world population shows a marked positive trend. This scenario leads to flooding and decreasing water quality, but also to a decrease in the availability of water resources in some regions. More than ever, drought is a significant threat to agriculture worldwide. This Special Issue focuses on recent advances in the mechanisms involved in the drought tolerance of crop plants, with particular attention to the role of the root tissue and shoot¿root interactions. In addition to drought, it considers other abiotic stresses involving water deficit stress at the cell level and their interactions with drought. The Special Issue includes a review paper and a collection of scientific papers that approach drought stress in cereals, legumes, and trees, combining studies in cultivated, wild, and model plants. Overall, this issue remarks the role of transcriptions factors (bHLH, NAC, HD-ZIP III), leucine-rich repeat receptor-like kinases, cytochrome P450 monooxygenases, and U-box E3 ligases in drought stress responses at different levels. In addition, the interaction between plant nutrition and drought stress responses is approached with a physiological strategy.

    Learning plant biodiversity in nature: the use of the citizen–science platform iNaturalist as a collaborative tool in secondary education
    (MDPI, 2021) Echeverría Obanos, Andrés; Ariz Arnedo, Idoia; Moreno Echeverría, Judit; Peralta de Andrés, Francisco Javier; González García, Esther; Zientziak; Institute for Multidisciplinary Research in Applied Biology - IMAB; Ciencias; Gobierno de Navarra / Nafarroako Gobernua, CENEDUCA3/2019
    Biodiversity is a concept of great scientific interest and social value studied in different subjects of the secondary education curriculum. Citizen–science programs may contribute to increasing the engagement of students when studying biodiversity. This work aimed to explore the use of the citizen–science platform iNaturalist as a complement of the elaboration of herbaria in an outdoor activity for 4th course 16-year-old students in the Basaula Reserve. The platform iNaturalist was chosen for its suitability to develop collaborative projects in an educational context. The Basaula project was created and 122 students were trained to record plant species in an outdoor activity. A total of 32 species were recorded, among them the most abundant were beech (Fagus sylvatica) and holm oak (Quercus ilex). The students positively evaluated their experience, highlighting its adequacy to record biodiversity data and make a virtual herbarium. Students valued the innovative character of iNaturalist and its usefulness for research but also the opportunity to integrate mobile devices in school education. We concluded that iNaturalist is a valuable tool to carry out collaborative projects dealing with biodiversity in secondary education.

    Strategies to aply water-deficit stress: similarities and disparities at the whole plant metabolism level in medicago truncatula
    (MDPI, 2021) Castañeda Presa, Verónica; González García, Esther; Ciencias; Zientziak; Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa
    Water-deficit stresses such as drought and salinity are the most important factors limiting crop productivity. Hence, understanding the plant responses to these stresses is key for the improvement of their tolerance and yield. In this study M. truncatula plants were subjected to 250 mM NaCl as well as reduced irrigation (No-W) and 250 g/L polyethylene glycol (PEG)-6000 to induce salinity and drought stress, respectively, provoking a drop to −1.7 MPa in leaf water potential. The whole plant physiology and metabolism was explored by characterizing the stress responses at root, phloem sap and leaf organ level. PEG treatment led to some typical responses of plants to drought stress, but in addition to PEG uptake, an important impairment of nutrient uptake and a different regulation of carbon metabolism could be observed compared to No-W plants. No-W plants showed an important redistribution of antioxidants and assimilates to the root tissue, with a distinctive increase in root proline degradation and alkaline invertase activity. On the contrary, salinity provoked an increase in leaf starch and isocitrate dehydrogenase activity, suggesting key roles in the plant response to this stress. Overall, results suggest higher protection of salt-stressed shoots and non-irrigated roots through different mechanisms, including the regulation of proline and carbon metabolism, while discarding PEG as safe mimicker of drought. This raises the need to understand the effect at the whole plant level of the different strategies employed to apply water-deficit stress.

    Editorial: Drought stress in legumes
    (Frontiers Media, 2022) Furlan, Ana Laura; González García, Esther; Roy Choudhury, Swarup; Signorelli, Santiago; Institute for Multidisciplinary Research in Applied Biology - IMAB; Gobierno de Navarra / Nafarroako Gobernua; Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa
    Plants are challenged by diverse environmental constraints, among which drought stress is increasingly important. Meteorological models predict an increase in the areas prone to drought in the future. Legumes are important sources of fiber, oils, and protein, constituting an essential amenity in the global economy. Additionally, legumes contribute to nitrogen input in the biosphere due to their ability to establish symbiotic interactions with diazotrophs, collectively named rhizobia. Therefore, efforts to decipher the molecular, metabolic, physiological, and agronomic responses are crucial contributing novel strategies to aid drought tolerance in legumes. This Research Topic contains articles either providing new findings or discussing the latest research concerning drought research in legumes, including one mini-review on soybean tolerance to drought (Arya et al.) and seven original research papers dealing with strategies to confer drought tolerance such as priming (Zhou et al.); studies on intraspecific variation in traits associated with drought tolerance (Prince et al.); the analysis of water use efficiency under terminal drought (Polania et al.); and the contribution of a legume dehydrin to drought tolerance (Sun et al.); the functional characterization of a LOX gene family (Mou et al.); the functional analysis of a soybean APETALA2/ETHYLENE RESPONSIVE FACTOR (AP2/ERF) (Wang et al.); and a study on AP2/ERF gene family in a tolerant desert legume (Zhao et al.).
