Two ectomycorrhizal truffles, Tuber melanosporum and T. aestivum , endophytically colonise roots of non‐ectomycorrhizal plants in natural environments
2020
International audience; Serendipitous findings and studies on Tuber species suggest that some ectomycorrhizal fungi, beyond their complex interaction with ectomycorrhizal hosts, also colonise roots of nonectomycorrhizal plants in a loose way called endophytism. Here, we investigate endophytism of T. melanosporum and T. aestivum . We visualised endophytic T. melanosporum hyphae by fluorescent in situ hybridisation on nonectomycorrhizal plants. For the two Tuber species, microsatellite genotyping investigated the endophytic presence of the individuals whose mating produced nearby ascocarps. We quantified the expression of four T. aestivum genes in roots of endophyted, non‐ectomycorrhizal plan…
Holm Oak Quercus ilex L.
2018
The holm oak is an evergreen tree species representative of Mediterranean forests. The largest populations of this species are in the Iberian Peninsula, forming the tree cover of an agro-silvo-pastoral system called “dehesa” in Spain and “montado” in Portugal. The high ecological and economic value of the species is of interest for rural development. The main current product are the acorns used for feeding Iberian black pigs, which are the basis of an important gastronomic industry. In addition, several bioactive compounds with new potential industrial applications in nutrition, pharmacology and cosmetics have been identified in acorns of oak species. Plantations with holm oak seedlings myc…
