Abstract
  • T. borchii is a very common truffle in Sardinia and in other Italian regions. It is a ubiquitous spedes as it can be found both in the inland hills and the coastal environment especial1y when covered by pine forests, in a wide range of variable soils from c1ayey types to the loose and sandy ones; with sub-alkaline, sub-acid and even acid reaction as in the cork oak stands of Gallura. In this survey the genetic variability of T. borchii was analysed by sequencing the ITSI-5.8SITS2 region and the genes coding for ~-tubulin and elongation factor l a (EF-l a), of 37 fungal samples collected in Sardinia, Apulia and Basilicata (ltaly). By sequence comparison it was found that in Sardinia there are two different groups of \"whitish truffle\", A and B, corresponding to the two cryptic species described by Bonuso et al. in Emilia Romagna and Sicily, with a BI subgroup, distinguishable only by ITS l and ITS2 sequences anaIysis. The results of this preliminary research confirmed the great genetic variability of T. borchii and the presence in this species of two or three groups of different genetic sequences which could indicate thc existence of as many populations comparabIe to sub-specific taxa. Waiting for future biogenetic and moiecular studies that shcd Iight on the differences characterising such taxa, T. borchii should be considered, in our opinion, as a complex species. (literal)
