Ancient tree genomes for old questions.

Most foundational work on the evolution and migration of plant species relies on genomic data from contemporary samples. Ancient plant samples can give us access to allele sequences and distributions on the landscape dating back to the mid Holocene or earlier (Gugerli et al., 2005).

A haplotype-resolved chromosome-scale genome for Quercus rubra L. provides insights into the genetics of adaptive traits for red oak species.

Northern red oak (Quercus rubra L.) is an ecologically and economically important forest tree native to North America. We present a chromosome-scale genome of Q.

Evidence for Glacial Refugia of the Forest Understorey Species (Ranunculaceae) in the Southern as Well as in the Northern Limestone Alps.

Glacial refugia of alpine and subnival biota have been intensively studied in the European Alps but the fate of forests and their understory species in that area remains largely unclear. In order to fill this gap, we aimed at disentangling the spatiotemporal diversification of disjunctly distributed black hellebore (Ranunculaceae). We applied a set of phylogeographic analyses based on restriction-site associated DNA sequencing (RADseq) data and plastid DNA sequences to a range-wide sampling of populations.

North American Douglas-fir (. in Europe: establishment and reproduction within new geographic space without consequences for its genetic diversity.

Genetic admixture and plasticity along with propagule pressure, large seed dispersal distances and fast adaptation support successful establishment and spread of introduced species outside their native range. Consequently, introductions may display climatic niche shifts in the introduced range. Douglas-fir, a controversial forest and ornamental conifer represented by two ecologically different and hybridising varieties, was transferred multiple times outside the native range in North America.

Development of novel microsatellite markers for by comparative transcriptomics.

Premise: (Boraginaceae) is an important medicinal herb with its main distribution across the Mediterranean region. To reveal its genetic variation and population structure, microsatellite markers were developed and validated in four Greek populations.

Methods And Results: RNA-Seq data of the related species and were assembled and mined to identify conserved ortholog sets containing simple sequence repeat motifs.
