The first results of a multidisciplinary study on the Messinian evaporitic interval of the Govone section (northwestern Italy), subdivided into several sedimentary cycles, are reported here. Primary sulphate evaporites and intercalated shaly deposits, which formed during the Messinian Salinity Crisis, contain well-preserved and taxonomically determinable terrestrial plant remains. Palynomorphs are present continuously all along the analysed succession and among them, pollen is especially abundant and diverse. Additionally, a few fragments of silicified wood (which are rare in the studied area) occurred in layers rich in phytodebris, but their analysis showed poor preservation of anatomy. Carpological remains are not abundant and are strongly altered by diagenesis. Compressed conifer shoots and angiosperm leaves are well-preserved in several layers, one of which yielded a particularly diverse assemblage. The various plant records have been integrated to obtain an initial general idea on the floristic composition of the assemblages and the palaeoenvironment. We hypothesize that a subtropical humid forest may have surrounded the basin, not only during the deposition of shale deposits, but also during the formation of gypsum, generally considered a product of arid climate. Despite the low-resolution sampling strategy for macrofossils, the identification of several relevant plant taxa (Engelhardia orsbergensis, Eurya stigmosa, Symplocos casparyi, Taiwania sp.), seems to indicate that the Govone section could provide an interesting glimpse into the composition of the palaeoflora of northern Italy during the deposition of the Messinian evaporites.

Available knowledge on the European white oaks (Quercus, sect. Quercus) plastome still exhibits large gaps, mostly in respect of detailed phylogeny and information from southern Europe and adjacent Near East. We investigated DNA sequence polymorphism at two plastid loci on 270 individuals representing 13 white oak species/taxa and retrieved several hundred sequences of the same two DNA regions from GenBank to fill the above gaps, and contribute to a better understanding of white oak diversity and evolution. The modern European sect. Quercus species exhibits a poorly differentiated plastid DNA, despite its current highly diversified taxonomy. Twenty-nine haplotypes were identified across the Euro-Mediterranean and Near East regions, including two ancestral variants that are westerly and south-easterly partitioned. Other high- and low-frequency haplotypes also showed a well-structured geographic distribution consistent with the current phytogeographic framework of the European continent. The climatic and geological events that characterized the end of the Tertiary and Quaternary periods played a crucial role in triggering haplotype mixing, isolation, and in offering niche opportunities for more recent diversification. Euro-Mediterranean southern territories host a high and as yet poorly studied genetic variation; the role of the Italian Peninsula as a crossroad and threshold for haplotype diversity and distribution clearly emerges from this study.
