“…Our results are in agreement with a large body of research on Mediterranean dry forests (de Román & Miguel, 2005, Martín-Pinto et al, 2006b, Buscardo et al, 2010, Hernández-Rodríguez et al, 2013 and specifically with some studies conducted also with P. pinaster (Buscardo et al, 2011, Gassibe et al, 2011, Sousa et al, 2011. Nonetheless, the overall evidence in this field cannot be considered as conclusive yet.…”

“…After a forest fire, the extent of the decrease in species richness (Smith et al, 2005, Hernández-Rodríguez et al, 2013 and relative abundance (Jonsson et al, 1999) and its further impact on forest regeneration depend on many factors such as variations in the intensity/severity of the fire, time elapsed after fire, the fire return interval and soil depth , Turrión et al, 2012. However, while the direct effect of fire is mainly destructive for existing fungal communities, at the same time fire also provides large inputs to new communities, mainly competition-free resources and substrates for fungi and plants to use (Penttilä & Kotiranta, 1996).…”

Aim of the study: Mycorrhizal fungi in Mediterranean forests play a key role in the complex process of recovery after wildfires. A broader understanding of an important pyrophytic species as Pinus pinaster and its fungal symbionts is thus necessary for forest restoration purposes. This study aims to assess the effects of ectomycorrhizal symbiosis on maritime pine seedlings and how fire severity affects fungal colonization ability.Area of study: Central Spain, in a Mediterranean region typically affected by wildfires dominated by Pinus pinaster, a species adapted to fire disturbance.Material and Methods: We studied P. pinaster root apexes from seedlings grown in soils collected one year after fire in undisturbed sites, sites moderately affected by fire and sites highly affected by fire. Natural ectomycorrhization was observed at the whole root system level as well as at two root vertical sections (0-10 cm and 10-20 cm). We also measured several morphometric traits (tap root length, shoot length, dry biomass of shoots and root/shoot ratio), which were used to test the influence of fire severity and soil chemistry upon them.Main results: Ectomycorrhizal colonization in undisturbed soils for total and separated root vertical sections was higher than in soils that had been affected by fire to some degree. Inversely, seedling vegetative size increased according to fire severity.Research highlights: Fire severity affected soil properties and mycorrhizal colonization one year after occurrence, thus affecting plant development. These findings can contribute to a better knowledge of the factors mediating successful establishment of P. pinaster in Mediterranean forests after wildfires.Keywords: Wildfire; mycorrhizal fungi; Maritime pine; bioassay.

“…Both total clearing and controlled burning increased bacterial richness, which may be explained by the increase in stand heterogeneity. Senescent C. ladanifer stands normally have a high density of the plants reaching almost total cover (Hernández‐Rodríguez et al ., ), which provides a rather homogeneous structure with a low diversity of niches. Both the total clearing and the controlled burning treatments essentially removes most of the closed scrublands, creating new available niches microorganisms.…”

Summary Cistus ladanifer scrublands, traditionally considered as unproductive, have nonetheless been observed to produce large quantities of king bolete (Boletus edulis) fruitbodies. These pyrophytic scrublands are prone to wildfires, which severely affect fungi, hence the need for fire prevention in producing C. ladanifer scrublands. In addition, B. edulis productions have severely decreased in the last years. A deeper understanding of the B. edulis life cycle and of biotic and abiotic factors influencing sporocarp formation is needed to implement management practices that facilitate B. edulis production. For example, some bacteria likely are involved in sporocarp production, representing a key part in the triple symbiosis (plant–fungus–bacteria). In this study, we used soil DNA metabarcoding in C. ladanifer scrublands to (i) assess the effect of site history and fire prevention treatment on bacterial richness and community composition; (ii) test if there was any correlation between various taxonomic groups of bacteria and mycelial biomass and sporocarp production of B. edulis; and to (iii) identify indicator bacteria associated with the most productive B. edulis sites. Our results show that site history drives bacterial richness and community composition, while fire prevention treatments have a weaker, but still detectable effect, particularly in the senescent plots. Sporocarp production correlated positively with genera in Verrucomicrobia. Several genera, e.g. Azospirillum and Gemmatimonas, were identified as indicators of the most productive sites, suggesting a potential biological role in B. edulis fructification. This study provides a better understanding of the triple symbiosis (plant–fungus–bacteria) involved in C. ladanifer–B. edulis systems.
