Few studies have investigated the genetic effects of forest wildfires. Species with perennial canopy seed banks in serotinous cones and soil or with long-distance seed and pollen dispersion can preserve genetic diversity and population differentiation under normal fire regimes. To test this hypothesis, we characterised molecularly Pinus pinaster Aiton (maritime pine) seedlings produced from seeds sampled in post-fire, naturally regenerated populations that had been subject to different fire regimes in the North of Portugal using inter-simple sequence repeats (ISSRs). The sampled populations burned once (A), twice (B), or three (D) times or had no prior fire history (C, control). Given the globally low seed germination ability, only 104 plantlets regenerated and were described. These plantlets were grouped according to their origin population. Intra-group ISSR polymorphism ranged from 72.73% (B) to 89.41% (D), revealing genetic differentiation among groups originating from populations that had experienced different fire recurrence. Overall, the unaffected genetic diversity of the regenerated plantlets allowed us to accept the hypothesis. Our findings enhance our understanding of the species ability to withstand fire-induced challenges and their responses to wildfires, guiding conservation endeavours and forest management strategies to bolster ecosystem resilience.<\/jats:p>","DOI":"10.3390\/fire7030088","type":"journal-article","created":{"date-parts":[[2024,3,15]],"date-time":"2024-03-15T14:05:25Z","timestamp":1710511525000},"page":"88","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Molecular Characterisation of Post-Fire Naturally Regenerated Populations of Maritime Pine (Pinus pinaster Ait.) in the North of Portugal"],"prefix":"10.3390","volume":"7","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6049-9291","authenticated-orcid":false,"given":"Ana","family":"Carvalho","sequence":"first","affiliation":[{"name":"Laborat\u00f3rio de Citogen\u00f3mica Vegetal, Departamento de Gen\u00e9tica e Biotecnologia, Universidade de Tr\u00e1s-os-Montes e Alto Douro (UTAD), Quinta de Prados, 5000-801 Vila Real, Portugal"},{"name":"Centro de Investiga\u00e7\u00e3o e Tecnologias Agroambientais e Biol\u00f3gicas (CITAB), Laborat\u00f3rio Associado Inov4Agro\u2014Instituto para a Inova\u00e7\u00e3o, Capacita\u00e7\u00e3o e Sustentabilidade de Produ\u00e7\u00e3o Agro-Alimentar, Universidade de Tr\u00e1s-os-Montes e Alto Douro (UTAD), Quinta de Prados, 5000-801 Vila Real, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3552-6582","authenticated-orcid":false,"given":"St\u00e9phanie","family":"Ribeiro","sequence":"additional","affiliation":[{"name":"Departamento de Ci\u00eancias Florestais e Arquitetura Paisagista (CIFAP), Universidade de Tr\u00e1s-os-Montes e Alto Douro (UTAD), Quinta de Prados, 5000-801 Vila Real, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2082-4205","authenticated-orcid":false,"given":"Maria Jo\u00e3o","family":"Gaspar","sequence":"additional","affiliation":[{"name":"Laborat\u00f3rio de Citogen\u00f3mica Vegetal, Departamento de Gen\u00e9tica e Biotecnologia, Universidade de Tr\u00e1s-os-Montes e Alto Douro (UTAD), Quinta de Prados, 5000-801 Vila Real, Portugal"},{"name":"Centro de Investiga\u00e7\u00e3o e Tecnologias Agroambientais e Biol\u00f3gicas (CITAB), Laborat\u00f3rio Associado Inov4Agro\u2014Instituto para a Inova\u00e7\u00e3o, Capacita\u00e7\u00e3o e Sustentabilidade de Produ\u00e7\u00e3o Agro-Alimentar, Universidade de Tr\u00e1s-os-Montes e Alto Douro (UTAD), Quinta de Prados, 5000-801 Vila Real, Portugal"},{"name":"Centro de Estudos Florestais (CEF), Instituto Superior de Agronomia, Universidade de Lisboa, Tapada da Ajuda, 1349-017 Lisboa, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6269-3605","authenticated-orcid":false,"given":"Teresa","family":"Fonseca","sequence":"additional","affiliation":[{"name":"Centro de Investiga\u00e7\u00e3o e Tecnologias Agroambientais e Biol\u00f3gicas (CITAB), Laborat\u00f3rio Associado Inov4Agro\u2014Instituto para a Inova\u00e7\u00e3o, Capacita\u00e7\u00e3o e Sustentabilidade de Produ\u00e7\u00e3o Agro-Alimentar, Universidade de Tr\u00e1s-os-Montes e Alto Douro (UTAD), Quinta de Prados, 5000-801 Vila Real, Portugal"},{"name":"Departamento de Ci\u00eancias Florestais e Arquitetura Paisagista (CIFAP), Universidade de Tr\u00e1s-os-Montes e Alto Douro (UTAD), Quinta de Prados, 5000-801 Vila Real, Portugal"},{"name":"Centro de Estudos Florestais (CEF), Instituto Superior de Agronomia, Universidade de Lisboa, Tapada da Ajuda, 1349-017 Lisboa, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6204-009X","authenticated-orcid":false,"given":"Jos\u00e9","family":"Lima-Brito","sequence":"additional","affiliation":[{"name":"Laborat\u00f3rio de Citogen\u00f3mica Vegetal, Departamento de Gen\u00e9tica e Biotecnologia, Universidade de Tr\u00e1s-os-Montes e Alto Douro (UTAD), Quinta de Prados, 5000-801 Vila Real, Portugal"},{"name":"Centro de Investiga\u00e7\u00e3o e Tecnologias Agroambientais e Biol\u00f3gicas (CITAB), Laborat\u00f3rio Associado Inov4Agro\u2014Instituto para a Inova\u00e7\u00e3o, Capacita\u00e7\u00e3o e Sustentabilidade de Produ\u00e7\u00e3o Agro-Alimentar, Universidade de Tr\u00e1s-os-Montes e Alto Douro (UTAD), Quinta de Prados, 5000-801 Vila Real, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2024,3,14]]},"reference":[{"key":"ref_1","unstructured":"P\u00f6rtner, H.-O., Roberts, D.C., Tignor, M., Poloczanska, E.S., Mintenbeck, K., Alegr\u00eda, A., Craig, M., Langsdorf, S., L\u00f6schke, S., and M\u00f6ller, V.
