The first layer, Pattern Triggered Immunity (PTI), is a powerful defense mechanism. It relies on Pattern Recognition Receptors (PRRs) to detect Microbe-Associated Molecular Patterns (MAMPs) from microbes, triggering a robust defense response. This response, including signaling cascades, gene expression changes, and production of antimicrobials and defense hormones, contributes to restricting pathogen colonization. PTI activation can trigger a systemic response known as Induced Systemic Resistance (IRS), enhancing plant defenses throughout the organism and leading to Non-Host-Resistance. The potential of PTI activation to enhance a plant's overall defensive capacity is a promising strategy to improve crop health. PTI activation at infection sites triggers the production of mobile signals within the plant, which then spread IRS throughout the plant, enhancing its overall defensive capacity. Flg22 and xyn11, two well-known MAMPs, trigger PTI in tomato, activating various defense responses and, interestingly, including IRS in tomatoes and other plants. Plant roots, often overlooked in discussions of plant immune systems, possess their own immune system, though less potent than leaves. They respond to MAMPs like Flg22 and chitin, but with weaker production of defense chemicals. Despite this difference, roots activate various defenses like PR proteins and callose deposition. Uniquely, roots secrete antifungal secondary metabolites like flavonoids. These root exudates play a crucial role in shaping the surrounding microbiome, attracting beneficial microbes, and possess antimicrobial activity itself. Studies have shown that root exudate composition can be manipulated to influence the soil microbiome and potentially enhance plant growth. This underlines the importance of considering roots in our understanding of plant immune systems, particularly how defense responses are displayed in the root after immune activation in leaves in terms of a systemic immune response. This often overlooked aspect is crucial for a comprehensive understanding of plant immunity. Plants and microbes communicate two-way, establishing an interaction, by instance, plant root exudates influence the composition of the rhizosphere microbiome, which in turn regulates plant growth and immunity. Research suggests that specific bacteria within the rhizosphere microbiome can enhance plant immunity. In fact, transplanting the microbiome from a resistant tomato variety to a susceptible one improved disease resistance. Understanding this plant-microbiome-soil interaction is crucial for developing sustainable agriculture. Our ongoing research investigates how soil type influences tomato immunity and its connection to the soil microbiome. Preliminary results show that different soil types affect the strength of plant immunity responses, even though the overall bacterial types (phyla) are similar. Interestingly, specific bacterial isolates from a soil type with higher immunity were able to directly trigger plant defense mechanisms. Unraveling the intricate interplay between soil type, the rhizosphere microbiome, and tomato immunity holds the key to unlocking sustainable and resilient agricultural practices. This proposal aims to investigate the potential of targeted Pattern-Triggered Immunity (PTI) activation in tomato leaves to enhance plant defense against diverse pathogens. We hypothesize that leaf application of microbial elicitors (flg22 and Xyn11) will trigger PTI, leading to changes in root gene expression and root exudate composition. These alterations are expected to enrich beneficial bacteria in the rhizosphere microbiome, ultimately enhancing resistance against both the foliar pathogen Pseudomonas syringae pv. tomato and the soil-borne pathogen Fusarium oxysporum f.sp. lycopersici. To achieve this, we have defined three specific objectives: 1) Evaluate the impact of leaf-applied elicitors on pathogen susceptibility, root gene expression, root exudate composition, and soil microbiome composition. 2) Develop synthetic exudates mimicking PTI-activated plants and construct synthetic microbial communities potentially containing beneficial bacteria. 3) Assess the effectiveness of leaf-applied elicitors and synthetic microbial communities on the root microbiome and plant health under field conditions. With this, we aim to elucidate the mechanisms by which leaf-based PTI activation influences root-level processes and shapes the rhizosphere microbiome to enhance tomato plant defense against various pathogens. The findings hold promise for developing novel and sustainable strategies for disease management in tomato production.[/vc_column_text][/vc_column][/vc_row][/vc_section][vc_section css=".vc_custom_1649209804184{background-color: #f6faff !important;}" el_class="p-md-0 pt-md-5"][vc_row el_class="container mx-auto align-items-center p-md-0 pt-5"][vc_column el_class="p-0"][/vc_column][/vc_row][/vc_section][vc_section css=".vc_custom_1649210787516{background-color: #f6faff !important;}" el_class="p-md-0 pt-md-5 pb-md-5"][vc_row el_class="container mx-auto align-items-center"][vc_column][/vc_column][/vc_row][/vc_section]

Drought intensification has been projected to increase in frequency in several regions across the globe, including the southwestern part of South America, the European Mediterranean Basin, Northern Africa, the Middle East, Central Asia, Australia, and the USA. Particularly, the former three areas have been recognized as locations highly likely to face unprecedented droughts during the 21st century, and within Southwestern South America, Chile has been alarmingly pointed out as the country earlier in this era experiencing this phenomenon, regardless of the greenhouse gas emissions scenario. Catastrophic effects such as extreme droughts and changes in fire behavior are important drivers of ecosystem degradation in arid, semiarid, dry temperate and Mediterranean ecosystems. Mediterranean ecosystems of central Chile have been indicated as the earliest in its type experiencing effects of climate change; where an accelerated aridification is already registered; therefore, representing a scenario to anticipate the effects of climate anomalies at other ecosystems of its type. Persistent droughts and land burning can compromise belowground conditions that are essential to support aboveground life in terrestrial ecosystems. Nevertheless, despite their importance for ecosystem functioning and recovery after environmental disturbances, there still a considerable lack of comprehension on how belowground attributes respond to combined stressors such as droughts and fires. This is of particular concern in conditions where post-fire plant and soil recovery have been shown to be inhibited or retarded due to severe droughts. Therefore, this project aims to evaluate individual and combined effects of drought and fires over time in soil microbial communities and carbon and nitrogen functional dynamics along with the relationship of these attributes and the state of sclerophyll vegetation in Mediterranean forests of central Chile. To accomplish this goal a multiscale approach will be applied in this research by integrating scientific disciplines from landcape ecology to molecular biology. By using remote sensing study site will be selected within an area known to be affected by an extended drought period (since 2010), in addition to hyper-dry years (2019 and 2021), which in addition has experienced the occurrence of historical wildfires as the case of 2017. From this initial screening 18 study conditions resulting from three climate anomaly categories identified (high, medium, low) according to differences in precipitation with respect to historical average, three categories for forest response to drought (recovered, unaffected and unrecovered) based on analysis of Normalized Burn Index (NBR = [NIR - SWIR] / [NIR + SWIR]) and two burned conditions (with and without) will be obtained for soil and vegetation assessments. Classical soil physicochemical analyses and NG-sequencing techniques including high-throughput amplicon sequencing (metabarcoding), whole genome sequencing (metagenomics), and gene expression (metatransciptomics), in addition to soil physiological analyses will be performed. Moreover, vegetation recovery following drought and fire will be evaluated. Results from this study will allow to better understand the individual versus the combined effects of drought and fires in soil microbial community structure and carbon and nitrogen functionality, which are expected to be exacerbated with the combined occurrence of these phenomena, giving insights on the resilience capacity of soil microbiomes and carbon and nitrogen biogeochemical cycles. From this work, results will also allow to gain a more comprehensive understanding of the linkages between soil functionality and vegetation responses to drought and fires over time, which will allow to identify ecological drivers related to ecosystem stability.[/vc_column_text][/vc_column][/vc_row][/vc_section][vc_section css=".vc_custom_1649209804184{background-color: #f6faff !important;}" el_class="p-md-0 pt-md-5"][vc_row el_class="container mx-auto align-items-center p-md-0 pt-5"][vc_column el_class="p-0"][/vc_column][/vc_row][/vc_section][vc_section css=".vc_custom_1649210787516{background-color: #f6faff !important;}" el_class="p-md-0 pt-md-5 pb-md-5"][vc_row el_class="container mx-auto align-items-center"][vc_column][/vc_column][/vc_row][/vc_section]

De esta forma, propusieron un conjunto de ideas (p.ej. legalidad, humanidad y proporcionalidad de las penas, debido proceso) para limitar el poder de castigo estatal, racionalizar el uso de la fuerza y disminuir la aplicación de la crueldad, llevando reformar el sistema penal de la época. El pensamiento de otros autores y la emergencia de los derechos humanos permitieron que estas ideas se incorporaran en las actuales democracias liberales comprometidas con el Estado de derecho. Así, en el ámbito penal, a nivel de leyes, constitucional y del derecho internacional, se construyó un sistema de protección del individuo frente al ius puniendi, y que aquí englobamos ampliamente bajo el término “Principios Penales liberales” (en adelante PPL) para referirnos a aquellos principios, sub-principios, ideas, derechos y/o garantías destinadas a limitar y racionalizar el ejercicio de la justicia penal. Aunque estos PPL se encuentran incorporados e institucionalizados, corrientes actuales como el Populismo Penal , la cultura del Control, la punitividad pública, el Derecho Penal del enemigo o los estudios en actitudes punitivas permitirían pensar que los PPL tendrían hoy un bajo respaldo ciudadano. Además, en el actual contexto chileno caracterizado por un incremento en la preocupación por la seguridad, es esperable que la opinión pública vea con reticencia estos PPLL por considerarse que favorecen a los delincuentes y limitan la capacidad estatal para controlar el crimen. Desde el ámbito político, que descansa en buena medida en la opinión pública, algunos actores plantean restablecer la pena de muerte, buscan limitar derecho a defensa gratuito o aumentar desproporcionadamente las penas. También, desde ciertos sectores políticos se ha presionado o cuestionado el actuar de jueces/as y fiscalía sin evaluar las consecuencias de estas acciones para la imparcialidad, en un contexto en el que el término de ‘garantismo jurídico’ parece ser concebido como como una característica negativa del sistema jurídico. Medidas y acciones de este tipo amenazan este conjunto de PPL y la protección del individuo frente al Estado. Dado que, desde el punto de vista politológico, las instituciones requieren de cierto umbral de respaldo subjetivo para su legitimidad social, resulta fundamental estudiar el apoyo ciudadano a los PPL que subyacen al sistema de justicia penal. A pesar, sin embargo, de la relevancia de este tema, la literatura en torno a lo que en adelante llamaremos las ‘Actitudes Ciudadanas hacia los Principios Penales Liberales’ (en adelante APPL) es sumamente escasa. Investigaciones previas solo han abordado el respaldo hacia ciertos principios aislados, hacia un set de PPL , pero no hacia el conjunto completo de PPL subyacentes al sistema de justicia. Sin embargoA pesar de lo anterior, investigación seminal y exploratoria en torno al tema se ha realizado en el contexto chileno identificándose una baja adhesión ciudadana a los PPL y, también,a la vez que, esto se han encontradomantendría un correlatos con el género, la educación y la orientación política de las personas. Por últimoOtro ejemplo de investigación emergente en la temática es, en Reino Unido. En este último páís -con sistema jurídico consuetudinario- se ha validado a nivel confirmatorio una escala (actualmente en revisión) para medir las APPL (en adelante E-APPL). Empero, esta escala no ha sido aplicada aun en otros países, o contextos con sistema de derecho escrito. Adicionalmente, tampoco hay hallazgos sobre los posibles factores explicativos de las APPL y sus consecuencias, relevándose entonces un vacío de conocimiento necesario de abordar. Considerando esto, y mediante una metodología mixta (cuantitativa y cualitativa), nuestra investigación busca estudiar las APPL en población residente en Chile. Específicamente, se busca a) describir los niveles y tipos APPL, b) los posibles factores que explican o dan cuenta de las APPL, y c) las consecuencias de las APPL para la legitimidad y confianza en el sistema de justicia chileno.[/vc_column_text][/vc_column][/vc_row][/vc_section][vc_section css=".vc_custom_1649209804184{background-color: #f6faff !important;}" el_class="p-md-0 pt-md-5"][vc_row el_class="container mx-auto align-items-center p-md-0 pt-5"][vc_column el_class="p-0"][/vc_column][/vc_row][/vc_section][vc_section css=".vc_custom_1649210787516{background-color: #f6faff !important;}" el_class="p-md-0 pt-md-5 pb-md-5"][vc_row el_class="container mx-auto align-items-center"][vc_column][/vc_column][/vc_row][/vc_section]

Therefore, states constantly seek survival, in which security plays a prominent role, surpassing all other issues (Waltz, 1979). The extent to which the movement of people across international borders has become a security issue is evident in how the migration-security nexus is prevalent in the current public and media debate around the globe, including Chile. This proposal stands on the premise that in a democratic society, mainstream media press is a highly significant actor in influencing levels of public concern and shaping people's attitudes towards social developments and phenomena, including migration and its securitization (Scherman et al., 2022; Ekman & Krzyzanowski, 2021). The representation of immigrants in mainstream media press creates opportunities for immigrants to either become part of society or be excluded from the public sphere. The main objective of this proposal is to analyze the media framing of the securitization of the "migration crisis" in the Chilean mainstream media press during 2014-2026. Further on, this main objective is broken down into three specific objectives (SO), namely: SO1: To identify the media news frames of the securitization of the "migration crisis" in Chilean mainstream press during 2014-2026. SO2: To analyze the consolidation of media news frames of the securitization of the "migration crisis" in Chilean mainstream press during 2014-2026. SO3: To compare the media news frames of the securitization of the "migration crisis" between the Northern, the Southern, and the Metropolitan Regions' mainstream press during 2014-2026. The empirical part includes the analysis of all informative pieces concerning the issues of security and immigration collected from the national editions of seven leading Chilean newspapers published in the Northern, Metropolitan, and Southern regions throughout a decade timespan (2014-2026). Such an elaborate dataset will reveal systematic longitudinal analysis across time, regions, and media outlets, providing a profound understanding of Chile's securitization of the "migration crisis." The proposed methodological paths for each SO are: SO1 will employ news framing analysis (de Vreese, 2005; Muñiz, 2011) to identify the media coverage frames of the securitization of the "migration crisis," applying a manual qualitative content analysis using Atlas. Ti 23 software for better coding manageability (Kovar, 2023; Vázquez-Herrero et al., 2022; Sarah-Liu, 2021). We will follow an inductive approach in which frames emerge from the collected corpus in situ (Semetko & Valkenburg, 2000) since it broadens the possibility of discovering a more amplified list of frames, thus contributing to a deeper analysis of the issue. SO2 will use a frequency analysis in Atlas.ti 23 and in Microsoft Excel (v2023) to identify and examine the most prominent media frames over the selected period. SO3 will follow a comparative analysis (Collier, 1993) to define similarities and/or differences between a) different media conglomerates (El Mercurio S.A.P and COPESA S.A) and independent outlets (Publimetro) and b) the Northern, the Metropolitan, and the Southern regions over the selected period. In addition, our longitudinal data (2014-2026) allows us to study possible changes in media framing covering the migration-security nexus over a decade, providing a comprehensive study on the issue currently under development across the national mainstream press. The main expected result is the generation of empirical evidence that advances understanding of the dominant frames of the securitization of the "migration crisis" in Chile. Given that most of the previous and current research on media securitization of migration has been EU or US-centered, our project calls for de-Westernizing this issue by contributing to a Latin American perspective to expand the geographical reach of research beyond European and US borders. As such, it offers new insights into the complexities of the securitization of the "migration crisis" in Chilean media and will contribute to the area of ​​Communication and Social Studies and anyone interested in migration and security issues. Likewise, since the securitization of migration reinforces a politics of fear and racism (Wodak, 2015), our findings may also concern the Ministry of the Interior and Public Security, which is responsible for public policies and laws regarding immigration. The association of migration with security can be reflected in laws and policies that the country may adopt toward migrants through limiting access to certain nationalities, changes in visa procedures, higher security controls, and, most importantly, deterioration of the rights of migrants (Planas Gifra, 2024). Finally, as this project will empirically identify migration-security patterns in the mainstream press and track their evolution, identifying potential shifts over a decade's time span, it will help us raise public and service awareness in Chile by generating policy papers, infographics, and seminars for the lay public and opinion columns in local and national media, among others.[/vc_column_text][/vc_column][/vc_row][/vc_section][vc_section css=".vc_custom_1649209804184{background-color: #f6faff !important;}" el_class="p-md-0 pt-md-5"][vc_row el_class="container mx-auto align-items-center p-md-0 pt-5"][vc_column el_class="p-0"][/vc_column][/vc_row][/vc_section][vc_section css=".vc_custom_1649210787516{background-color: #f6faff !important;}" el_class="p-md-0 pt-md-5 pb-md-5"][vc_row el_class="container mx-auto align-items-center"][vc_column][/vc_column][/vc_row][/vc_section]

SO3: To compare the media news frames of the securitization of the "migration crisis" between the Northern, the Southern, and the Metropolitan Regions' mainstream press during 2014-2026. The empirical part includes the analysis of all informative pieces concerning the issues of security and immigration collected from the national editions of seven leading Chilean newspapers published in the Northern, Metropolitan, and Southern regions throughout a decade timespan (2014-2026). Such an elaborate dataset will reveal systematic longitudinal analysis across time, regions, and media outlets, providing a profound understanding of Chile's securitization of the "migration crisis." The proposed methodological paths for each SO are: SO1 will employ news framing analysis (de Vreese, 2005; Muñiz, 2011) to identify the media coverage frames of the securitization of the "migration crisis," applying a manual qualitative content analysis using Atlas. Ti 23 software for better coding manageability (Kovar, 2023; Vázquez-Herrero et al., 2022; Sarah-Liu, 2021). We will follow an inductive approach in which frames emerge from the collected corpus in situ (Semetko & Valkenburg, 2000) since it broadens the possibility of discovering a more amplified list of frames, thus contributing to a deeper analysis of the issue. SO2 will use a frequency analysis in Atlas.ti 23 and in Microsoft Excel (v2023) to identify and examine the most prominent media frames over the selected period. SO3 will follow a comparative analysis (Collier, 1993) to define similarities and/or differences between a) different media conglomerates (El Mercurio S.A.P and COPESA S.A) and independent outlets (Publimetro) and b) the Northern, the Metropolitan, and the Southern regions over the selected period. In addition, our longitudinal data (2014-2026) allows us to study possible changes in media framing covering the migration-security nexus over a decade, providing a comprehensive study on the issue currently under development across the national mainstream press. The main expected result is the generation of empirical evidence that advances understanding of the dominant frames of the securitization of the "migration crisis" in Chile. Given that most of the previous and current research on media securitization of migration has been EU or US-centered, our project calls for de-Westernizing this issue by contributing to a Latin American perspective to expand the geographical reach of research beyond European and US borders. As such, it offers new insights into the complexities of the securitization of the "migration crisis" in Chilean media and will contribute to the area of ​​Communication and Social Studies and anyone interested in migration and security issues. Likewise, since the securitization of migration reinforces a politics of fear and racism (Wodak, 2015), our findings may also concern the Ministry of the Interior and Public Security, which is responsible for public policies and laws regarding immigration. The association of migration with security can be reflected in laws and policies that the country may adopt toward migrants through limiting access to certain nationalities, changes in visa procedures, higher security controls, and, most importantly, deterioration of the rights of migrants (Planas Gifra, 2024). Finally, as this project will empirically identify migration-security patterns in the mainstream press and track their evolution, identifying potential shifts over a decade's time span, it will help us raise public and service awareness in Chile by generating policy papers, infographics, and seminars for the lay public and opinion columns in local and national media, among others.[/vc_column_text][/vc_column][/vc_row][/vc_section][vc_section css=".vc_custom_1649209804184{background-color: #f6faff !important;}" el_class="p-md-0 pt-md-5"][vc_row el_class="container mx-auto align-items-center p-md-0 pt-5"][vc_column el_class="p-0"][/vc_column][/vc_row][/vc_section][vc_section css=".vc_custom_1649210787516{background-color: #f6faff !important;}" el_class="p-md-0 pt-md-5 pb-md-5"][vc_row el_class="container mx-auto align-items-center"][vc_column][/vc_column][/vc_row][/vc_section]
