The presence and strength of post-pollination barriers in an orchid lineage that lacks pollinator specialization Open
Background and Aims Post-pollination pre-zygotic barriers involve interactions between the pollen, pistil and ovules that impede fertilization by heterospecific pollen. These barriers act sequentially when pollen from different donors simu…

The evolutionary history of the common bean (Phaseolus vulgaris) revealed by chloroplast and nuclear genomes analysis Open
Key message The origin of common bean was investigated throughout chloroplast and nuclear WGS data considering recombination events. Our results support the Mesoamerican origin of common bean. Abstract The remarkable evolutionary history o…

Early sex identification by leaflet distance in plantlets of Cycas revoluta Open
In dioecious plants, the process of sex determination usually occurs during the reproductive stage. However, it can be challenging to determine the sex of long-lived plants with long generation times. This is true for Cycas revoluta , whic…

The evolutionary history of the common bean (<i>Phaseolus vulgaris</i>) revealed by chloroplast and nuclear genomes Open
The remarkable evolutionary history of the common bean ( Phaseolus vulgaris L. ) has led to the emergence of three wild main genepools corresponding to three different ecogeographic areas: Mesoamerica, the Andes and northern Peru/Ecuador. …

Reproductive character displacement allows two sexually deceptive orchids to coexist and attract the same specific pollinator Open
An increased divergence in characters between species in secondary contact can be shaped by selection against competition for a common resource (ecological character displacement, ECD) or against maladapted hybridization (reproductive char…

Hopping or Jumping on the Cliffs: The Unusual Phylogeographical and Demographic Structure of an Extremely Narrow Endemic Mediterranean Plant Open
Several past and recent climatic and geological events have greatly influenced the current distribution of coastal species around the Mediterranean Basin. As a consequence, the reconstruction of the distributional history of these species …

DNA barcoding of native Caucasus herbal plants: potentials and limitations in complex groups and implications for phylogeographic patterns Open
DNA barcoding has rapidly become a useful complementary tool in floristic investigations particularly for identifying specimens that lack diagnostic characters. Here, we assess the capability of three DNA barcode markers (chloroplast rpoB …

Cultivated Tomato (Solanum lycopersicum L.) Suffered a Severe Cytoplasmic Bottleneck during Domestication: Implications from Chloroplast Genomes Open
In various crops, genetic bottlenecks occurring through domestication can limit crop resilience to biotic and abiotic stresses. In the present study, we investigated nucleotide diversity in tomato chloroplast genome through sequencing seve…

Phenotypic expression of floral traits in hybrid zones provides insights into their genetic architecture Open
Summary Information on the genetic architecture of phenotypic traits is helpful for constructing and testing models of the ecoevolutionary dynamics of natural populations. For plant groups with long life cycles there is a lack of line cros…

View article: The influence of a relict distribution on genetic structure and variation in the Mediterranean tree,<i>Platanus orientalis</i>
The influence of a relict distribution on genetic structure and variation in the Mediterranean tree,<i>Platanus orientalis</i> Open
The distribution of plant species around the Mediterranean basin is a product of the influence of both geographical barriers and of climatic changes experienced during the Tertiary, with the transition from a warm to cool periods. Several …

The complete plastid genomes of Ophrys iricolor and O. sphegodes (Orchidaceae) and comparative analyses with other orchids Open
Sexually deceptive orchids of the genus Ophrys may rapidly evolve by adaptation to pollinators. However, understanding of the genetic basis of potential changes and patterns of relationships is hampered by a lack of genomic information. We…

Strong but permeable barriers to gene exchange between sister species of <i>Epidendrum</i> Open
PREMISE OF THE STUDY: The investigation of reproductive barriers between sister species can provide insights into how new lineages arise, and how species integrity is maintained in the face of interspecific gene flow. Different pre‐ and po…

Transitions between self-compatibility and self-incompatibility and the evolution of reproductive isolation in the large and diverse tropical genus<i>Dendrobium</i>(Orchidaceae) Open
Transitions between SC and SI and the gradual accumulation of genetic incompatibilities affecting postzygotic isolation are important mechanisms preventing gene flow among Dendrobium species, and may constitute important evolutionary proce…
