Phylogenetics of Ochna (Ochnaceae) and a new infrageneric classification.
Advances in high-throughput DNA sequencing are allowing faster and more affordable generation of molecular phylogenetic trees for many organisms. However, resolving relationships at species level is still challenging, particularly for taxonomically difficult groups. Until recently, the classification of Ochna had been based only on morphological data. Here, we present the...Shah, Toral ; Mashimba, Fandey H. ; Suleiman, Haji O. ; Mbailwa, Yahya S ; Schneider, Julio V …

Genetic assimilation of ancestral plasticity during parallel adaptation to zinc contamination in Silene uniflora.
Phenotypic plasticity in ancestral populations is hypothesized to facilitate adaptation, but evidence is piecemeal and often contradictory. Further, whether ancestral plasticity increases the probability of parallel adaptive changes has not been explored. The most general finding is that ancestral responses to a new environment are reversed following adaptation (known as... -

The Implications of Incongruence between Gene Tree and Species Tree Topologies for Divergence Time Estimation.
Phylogenetic analyses are increasingly being performed with data sets that incorporate hundreds of loci. Due to incomplete lineage sorting, hybridization, and horizontal gene transfer, the gene trees for these loci may often have topologies that differ from each other and from the species tree. The effect of these topological incongruences...Carruthers, Tom ; Sun, Miao ; Baker, William J. ; Smith, Stephen A. ; de Vos, Jurriaan M. …

Estimation of species divergence times in presence of cross-species gene flow.
Cross-species introgression can have significant impacts on phylogenomic reconstruction of species divergence events. Here, we used simulations to show how the presence of even a small amount of introgression can bias divergence time estimates when gene flow is ignored in the analysis. Using advances in analytical methods under the multispecies...Tiley, George P ; Flouri, Tomás ; Jiao, Xiyun ; Poelstra, Jelmer W. ; Xu, Bo …

Metagenomics Shines Light on the Evolution of ‘Sunscreen’ Pigment Metabolism in the Teloschistales (Lichen-Forming Ascomycota).
Fungi produce a vast number of secondary metabolites that shape their interactions with other organisms and the environment. Characterising the genes underpinning metabolite synthesis is therefore key to understanding fungal evolution and adaptation. Lichenised fungi represent almost one-third of Ascomycota diversity and boast impressive secondary metabolites repertoires. However, most lichen... -

First evidence of a monodominant (Englerodendron, Amherstieae, Detarioideae, Leguminosae) .tropical moist forest from the early Miocene (21.73 Ma) of Ethiopia
Many tropical wet forests are species-rich and have relatively even species frequency distributions. But, dominance by a single canopy species can also occur in tropical wet climates and can remain stable for centuries. These are uncommon globally, with the African wet tropics supporting more such communities than the Neotropics or... -

Phylogeography and conservation gaps of Musa balbisiana Colla genetic diversity revealed by microsatellite markers.
Collection and storage of crop wild relative (CWR) germplasm is crucial for preserving species genetic diversity and crop improvement. Nevertheless, much of the genetic variation of CWRs is absent in ex situ collections and detailed passport data are often lacking. Here, we focussed on one of the two main progenitor...Mertens, Arne ; Bawin, Yves ; Vanden Abeele, Samuel ; Kallow, Simon ; Swennen, Rony …

Conical petal epidermal cells, regulated by the MYB transcription factor MIXTA, have an ancient origin within the angiosperms.
Conical epidermal cells occur on the tepals (perianth organs, typically petals and/or sepals) of the majority of animal-pollinated angiosperms, where they play both visual and tactile roles in pollinator attraction, providing grip to foraging insects and enhancing colour, temperature and hydrophobicity. To explore the evolutionary history of conical epidermal cells...Reed, Alison ; Rudall, Paula J ; Brockington, Samuel F ; Glover, Beverley J

Disentangling the causes of temporal variation in the opportunity for sexual selection.
In principle, temporal fluctuations in the potential for sexual selection can be estimated as changes in intrasexual variance in reproductive success (i.e. the opportunity for selection). However, we know little about how opportunity measures vary over time, and the extent to which such dynamics are affected by stochasticity. We use...Carleial, Rômulo ; Pizzari, Tommaso ; Richardson, David S. ; McDonald, Grant C.
