dc.description.abstract | Suillus fungal specimens of pine forests from a Mediterranean area of central Spain (Madrid region) were studied based on molecular and physiological analysis of sporocarps to obtain fungal native inocula to produce mycorrhizal Pinus halepensis Miller in nursery. Variation within the internal transcribed spacer (ITS) region of the ribosomal RNA genes of Suillus was examined by restriction fragment length polymorphism (RFLP) and direct sequencing of polymerase chain reaction products. Ribosomal DNA (rDNA) spacers were amplified from pure cultures obtained from fruit bodies of a range of Suillus species: Suillus bellinii (Inzenga) Watling, Suillus bovinus (Pers.) Kuntze, Suillus collinitus (Fr.) Kuntze, Suillus granulatus (L.) Snell, Suillus mediterraneensis (Jacquet. & Blum) Redeuil, Suillus luteus L. (Gray), and Suillus variegatus (Sw.) Kuntze. Interspecific variation in the length and number of restriction sites of the amplified ITS region was observed. This variation was confirmed by sequencing, which allowed us to identify some isolates. This is the first time that the ITS sequence of S. mediterraneensis is completely described. No intraspecific rDNA variation was observed within isolates of S. collinitus, S. mediterraneensis, and S. luteus. The phylogenetic analysis established the close relationship among these Mediterranean fungal species. As a further step to characterize the different isolates and to understand the relation between genetic and functional diversity, some physiological variables were evaluated. Intraspecific variation in axenic fungal growth and in mycorrhizal capacities was detected, especially within S. collinitus isolates. The fungal isolates stimulated the growth of P. halepensis in different rates. These studies indicated that ITS analysis, in conjunction with mycorrhizal tests, provides suitable combined tools for the analysis of Suillus spp. in a small geographic area for selecting isolates with final afforestation purposes. | es_ES |
