A better understanding of the germination behaviour of Aegilops species is important to improve their use in breeding programmes and strengthen their in situ/ex situ conservation. In this study, we investigated the germination behaviour of nine Aegilops species, five of them not yet investigated, under two alternating and two constant temperatures. Seed germination was higher than 60% in all temperature treatments and species. Alternating temperatures promoted higher germination rates in all the species and significantly enhanced seed germination in three species (Aegilops biuncialis, Aegilops geniculata and Aegilops neglecta), in comparison with constant temperatures. One of the rarest and least productive species in the genus (Aegilops uniaristata) displayed the highest germination. This study suggests that different (seed) regeneration strategies/niches occur across Aegilops species."

Reintroduction of a dioecious aquatic macrophyte (Stratiotes aloides L.) regionally extinct in the wild. Interesting answers from genetics / Simone Orsenigo in Aquatic Conservation : Marine and Freshwater Ecosystems, vol. 27, n°1 (Février 2017)

Public [article]  inAquatic Conservation : Marine and Freshwater Ecosystems > vol. 27, n°1 (Février 2017) . - pp. 10-23 Titre : Reintroduction of a dioecious aquatic macrophyte (Stratiotes aloides L.) regionally extinct in the wild. Interesting answers from genetics Type de document : Livre Auteurs : Simone Orsenigo, Auteur ; Rodolfo Gentili, Auteur ; Alfons J.P. Smolders, Auteur ; Andrey Efremov, Auteur ; Graziano Rossi, Auteur ; Nicola M. G. Ardenghi, Auteur ; Sandra Citterio, Auteur ; Thomas Abeli, Auteur Année de publication : 2017 Article en page(s) : pp. 10-23 Langues : Anglais Mots-clés : lake  pond  plante menacée  genetics  reintroduction  macrophyte  nutrient enrichment  pollution Résumé : "The reintroduction of a plant species regionally extinct in the wild poses a stimulating conservation challenge. If the species is dioecious and the ex situ preserved population is only of one sex, the challenge is even more difficult. To assess whether the female population of Stratiotes aloides originally studied requires a reinforcement to increase its genetic variation, and to determine from which source male individuals should be taken to re‐establish a viable population, the genetic structure of nine different accessions of S. aloides across Europe and Asia were analysed – six native populations and the last three Italian populations, preserved ex situ. Amplified fragment length polymorphism (AFLP) fingerprinting of 190 individuals from these populations was performed using six primer combinations and chromosome counts. AFLP markers revealed medium to high values of genetic diversity at the population level, unexpectedly including residual ex situ accessions. Neighbour‐joining tree, PCoA and STRUCTURE analyses indicate the presence of three genetic patterns identifiable in the central‐western, central and eastern Europe–Asian populations. Chromosome counts revealed the presence of diploid (2n = 24) and tetraploid (2n = 48) populations. Similarity between populations belonging to different hydrographical basins, and differences between neighbouring populations could be explained through long‐distance bird‐mediated dispersal events. Genetic analysis showed that reinforcement with female individuals from other European populations to increase the genetic diversity of the Italian female population is not necessary. Surprisingly, the geographically closest male population (Bavaria) to the Po basin is not the best option for male reintroduction. Instead, male individuals should be reintroduced from the Rhine basin (Netherlands) and eastern part of the Danube basin (Romania)."

Original and detailed descriptions, illustrations and information on distribution and ecology are provided, along with an updated identification key. Late-season leaf pigmentation, presence/absence of phylloxera galls, ripe berries flavor, and seed morphology proved to be useful characters for the identification of the treated species and nothospecies. Nomenclatural aspects regarding V. riparia × V. vinifera are also discussed."

The current paper analyzes the taxonomy and the distribution of seven taxa recorded in Italy and assigns new names to three nothospecies, naturalized and/or invasive in additional European countries: V. ×instabilis (= V. riparia × V. rupestris), V. ×koberi (= V. berlandieri × V. riparia), V. ×ruggerii (= V. berlandieri × V. rupestris). Nomenclatural and systematic aspects regarding V. vinifera are also discussed.
