Identifying and naming the currently known diversity of the genus Hydnum, with an emphasis on European and North American taxa.

In this study, 49 species of Hydnum are recognized worldwide. Twenty-two of them are described here as new species. Epitypes are proposed for H.

The genus (): a ribosomal DNA-based phylogeny and revised systematics of European 'deer truffles'.

('deer truffles') is one of the most important ectomycorrhizal fungal genera in temperate and subarctic forest ecosystems, but also one of the least documented in public databases. The current systematics are mainly based on macromorphology, and is not significantly different from that proposed by Vittadini (1831). Within the 49 species recognised worldwide, 23 were originally described from Europe and 17 of these were described before the 20th century.

Filamin isoforms in molluscan smooth muscle.

The role of filamin in molluscan catch muscles is unknown. In this work three proteins isolated from the posterior adductor muscle of the sea mussel Mytilus galloprovincialis were identified by MALDI-TOF/TOF MS as homologous to mammalian filamin. They were named FLN-270, FLN-230 and FLN-105, according to their apparent molecular weight determined by SDS-PAGE: 270kDa, 230kDa and 105kDa, respectively.

Isoforms of cAMP-dependent protein kinase in the bivalve mollusk Mytilus galloprovincialis: activation by cyclic nucleotides and effect of temperature.

Two different isoforms of cAMP-dependent protein kinase (PKA) have been partially purified from the posterior adductor muscle and the mantle tissue of the sea mussel Mytilus galloprovincialis. The holoenzymes contain as regulatory subunit (R) the previously identified isoforms Rmyt1 and Rmyt2, and were named PKAmyt1 and PKAmyt2, respectively. Both cAMP and cGMP can activate these PKA isoforms completely, although they exhibit a sensitivity approximately 100-fold higher for cAMP than for cGMP.
