Are local action groups, under LEADER approach, a good way to support resilience in rural areas?

The LEADER approach is a tool of governance in rural areas in Spain since its launch as a Community initiative, more than two decades ago. Its contribution to the development of rural areas, and their adaptation to the changes that have occurred in the last twenty years, are decisive. For local action groups (LAGs), the existence of networks that grouped them, is essential for the development of the methodology, the transmission of information and the relationship with governments, at regional, national and European level. Both, LAGs and networks can play an important role to analyze the effects of the economic crisis in rural areas and the capacity of resilience. This paper analyzes the role of LAGs and the existing rural development networks in Spain, their functioning, how LAGs adapt themselves to the crisis, how they are supported by the mentioned networks, and how they can contribute to the resilience in rural areas

An indicator of political diversity for analyzing their influence in shaping the local action groups leader in Spain

Between 1987 and 2013 Spain has implemented programs of rural development through the LEADER methodology, all of them led and managed by Local Action Groups (LAG). The influence of municipal governments within these GAL is a subject discussed from the beginning but lacks specificity in terms of quantitative data. . This paper identifies two indicators to measure patterns representing municipal governments. From these different situations of interest include the influence of the balance of political parties in the initial constitution of the LAG and its evolution over time, and the power of internal political negotiation of a LAG that the majority political party is faced with are analyzed the other political parties of the same LAG

Differential Expression of Fungal Genes Determines the Lifestyle of Plectosphaerella Strains During Arabidopsis thaliana Colonization

16 Päg.The fungal genus Plectosphaerella comprises species and strains with different lifestyles on plants, such as P. cucumerina, which has served as model for the characterization of Arabidopsis thaliana basal and nonhost resistance to necrotrophic fungi. We have sequenced, annotated, and compared the genomes and transcriptomes of three Plectosphaerella strains with different lifestyles on A. thaliana, namely, PcBMM, a natural pathogen of wild-type plants (Col-0), Pc2127, a nonpathogenic strain on Col-0 but pathogenic on the immunocompromised cyp79B2 cyp79B3 mutant, and P0831, which was isolated from a natural population of A. thaliana and is shown here to be nonpathogenic and to grow epiphytically on Col-0 and cyp79B2 cyp79B3 plants. The genomes of these Plectosphaerella strains are very similar and do not differ in the number of genes with pathogenesis-related functions, with the exception of secreted carbohydrate-active enzymes (CAZymes), which are up to five times more abundant in the pathogenic strain PcBMM. Analysis of the fungal transcriptomes in inoculated Col-0 and cyp79B2 cyp79B3 plants at initial colonization stages confirm the key role of secreted CAZymes in the necrotrophic interaction, since PcBMM expresses more genes encoding secreted CAZymes than Pc2127 and P0831. We also show that P0831 epiphytic growth on A. thaliana involves the transcription of specific repertoires of fungal genes, which might be necessary for epiphytic growth adaptation. Overall, these results suggest that in-planta expression of specific sets of fungal genes at early stages of colonization determine the diverse lifestyles and pathogenicity of Plectosphaerella strains.This work was supported by the Spanish Ministry of Economy and Competitiveness (MINECO) grant BIO2015-64077-R and the Spanish Research Agency (AEI) grant RTI2018-096975-B-I00 to A.

Clonal chromosomal mosaicism and loss of chromosome Y in elderly men increase vulnerability for SARS-CoV-2

The pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2, COVID-19) had an estimated overall case fatality ratio of 1.38% (pre-vaccination), being 53% higher in males and increasing exponentially with age. Among 9578 individuals diagnosed with COVID-19 in the SCOURGE study, we found 133 cases (1.42%) with detectable clonal mosaicism for chromosome alterations (mCA) and 226 males (5.08%) with acquired loss of chromosome Y (LOY). Individuals with clonal mosaic events (mCA and/or LOY) showed a 54% increase in the risk of COVID-19 lethality. LOY is associated with transcriptomic biomarkers of immune dysfunction, pro-coagulation activity and cardiovascular risk. Interferon-induced genes involved in the initial immune response to SARS-CoV-2 are also down-regulated in LOY. Thus, mCA and LOY underlie at least part of the sex-biased severity and mortality of COVID-19 in aging patients. Given its potential therapeutic and prognostic relevance, evaluation of clonal mosaicism should be implemented as biomarker of COVID-19 severity in elderly people. Among 9578 individuals diagnosed with COVID-19 in the SCOURGE study, individuals with clonal mosaic events (clonal mosaicism for chromosome alterations and/or loss of chromosome Y) showed an increased risk of COVID-19 lethality
