The success of truffle cultivation depends especially on the quality of mycorrhizal seedlings, which are typically produced under aseptic conditions to avoid contamination by unwanted fungi. However, such practices may also eliminate beneficial microorganisms that could support truffle symbiosis, improving seedling quality and enhancing field establishment of truffle plantations. In this study, a set of 12 endophytic bacteria and fungi isolated from the Tuber melanosporum environment (gleba tissue, mycorrhizae and truffle brûlé) was tested on Quercus ilex seedlings under nursery conditions. Co-inoculation with a strain of Agrobacterium tumefaciens significantly enhanced root colonization by T. melanosporum and exhibited in vitro plant growth-promoting traits, supporting its potential role as mycorrhizal helper bacterium. In contrast, a strain of Trichoderma harzianum negatively affected mycorrhization. None of the tested strains showed significant effects on seedling growth. Our findings support the hypothesis that specific bacterial strains associated with truffles can act as mycorrhizal helper bacteria, highlighting their potential for co-inoculation strategies to enhance quality of truffle seedlings in nurseries. However, most of the tested microorganisms did not show a significant effect on seedling mycorrhization or growth, underscoring the need for further research to better understand the interactions within the mycorrhizosphere, in order to improve seedling quality., Diputación Provincial de Huesca (collaboration agreement DPH-CITA), Peer reviewed

Individual variation among and within natural populations can have eco-evolutionary implications by, for example, affecting species interactions or evolutionary potential. Urban systems present a unique opportunity to evaluate how environmental change shapes variation since urban phenotypic differentiation is widely documented on contemporary timescales. We introduce and test three hypotheses to determine how urbanization affects phenotypic variation at different population levels. Combining 21 long-term datasets in a mega-analysis approach, we synthesize how urbanization impacts variation in tarsus length and lay date among and within subpopulations of great and blue tits (Parus major, Cyanistes caeruleus) at a continental scale. Our synthesis reveals that urbanization is associated with increased phenotypic variation within subpopulations by 11% on average, and by as much as 25% across the species and traits examined. We also find some evidence (for tarsus length in great tits) that urbanization increases differentiation between subpopulations. We did not, however, find that urbanization increases differences between subpopulations in their within-subpopulation variation. Our synthesis provides novel insights into how urban contexts impact individual diversity at different spatial scales and we highlight future directions that could establish the genetic and environmental effects that underlie these continental patterns of urban phenotypic variation., Agence Nationale de la Recherche : ANR-19-CE34-0008-05, URBANTIT; Fonds de Recherche du Québec – Nature et Technologies, Grant / PhD scholarship; Natural Sciences and Engineering Research Council, Canadian Graduate Scholarship; Centre Méditerranéen de l’Environnement et de la Biodiversité, Mobility Grant; Centre National de la Recherche Scientifique, SEE-Life., Peer reviewed
