With the rapid reduction in sequencing costs of high-throughput genomic data, it has become commonplace to use hundreds of genes/sites to infer phylogeny of any study system. While sampling large number of genes has given us a tremendous opportunity to uncover previously unknown relationships and improve phylogenetic resolution, it also presents us with new challenges when the phylogenetic signal is confused by differences in the evolutionary histories of sampled genes. Given the addition of acc...

Abstract Saccharina latissima is a perennial kelp with a circumboreal distribution from the North Pacific to the North Atlantic coasts. Our study clarified the taxonomy of the morphologically distinct Saccharina latissima forma angustissima (Collins) A.Mathieson from the low intertidal zone on exposed islands and ledges of Casco Bay, Maine, USA. To identify genetic divergence between the two morphotypes, S. latissima and S. latissima f. angustissima, we used a multilocus phylogenetic approach in...

Interactions between fungi and plants, including parasitism, mutualism, and saprotrophy, have been invoked as key to their respective macroevolutionary success. Here we evaluate the origins of plant-fungal symbioses and saprotrophy using a time-calibrated phylogenetic framework that reveals linked and drastic shifts in diversification rates of each kingdom. Fungal colonization of land was associated with at least two origins of terrestrial green algae and preceded embryophytes (as evidenced by l...

The evolution of oxygenic photosynthesis by cyanobacteria was arguably one of the most significant biological events in Earth’s history, shaping the atmosphere and subsequently leading to diverse ecosystems (1). The permanent endosymbiotic merger between a cyanobacterium and a unicellular heterotrophic eukaryote in deep evolutionary time set the stage for the stunning diversity of photosynthetic eukaryotes and ecosystems seen today, giving rise to the supergroup Archaeplastida, the red, glaucoph...

Abstract: In molecular phylogenetic trees of zoospore-producing unicellular chlorophycean algae, well-resolved lineages often do not correspond to current taxonomic categories, and therefore characterising diagnostic morphological traits of lineages can be challenging. We employed a phylogenetic framework to examine the evolution of light microscopic (LM) and transmission electron microscopic (TEM) features in the phylogroup Moewusinia and a related genus and then assessed the features that coul...

The phylogenetic placement of Prasiola calophylla, from an anthropogenic habitat previously shown to contain a novel UV sunscreen compound, was confirmed by analysis of its rbcL gene. This alga has the capacity to tolerate strong water-limiting conditions. The photosynthetic performance and ultrastructural changes under desiccation and osmotic stress were investigated. Freshly harvested thalli showed an effective quantum yield of PSII [Y(II)] of 0.52 ± 0.06 that decreased to ∼60% of the initial ...

AbstractTwo non-native stalk-forming diatoms that were recently observed in the West Branch of the Farmington River, a tributary of the Connecticut River in Connecticut (USA), are characterized morphologically and barcode marker sequences were obtained for each of them. Cymbella janischii, the dominant stalk-forming species during the summer of 2012, previously had not been found in the northeastern USA. Samples of C. janischii were examined microscopically and used to obtain four sequences of t...

A resurgence of green algal taxonomy over the last decade has resulted from investigations of unusual and previously poorly sampled habitats (e.g., Neustupa et al., 2011 ; Ramos et al., 2015 ; Caisova et al., 2015 ), from the application of molecular methods to resolve cryptic taxa (e.g., Fucikova et al., 2014a ), and through taxonomic clarifi cation of known species (e.g., Sanchez-Puerta et al., 2006 ; Caisova et al., 2011 ; Hegewald et al., 2013 ; Skaloud et al., 2013b ). Even aquatic habitats...
