Independent evidence from morphological, ultrastructural, biochemical, and molecular data have shown that land plants originated from charophycean green algae. However, the branching order within charophytes is still unresolved, and contradictory phylogenies about, for example,the position of the unicellular green alga Mesostigma viride are difficult to reconcile. A comparison of nuclear-encode...

In the past decade, an increasing number of plant genomes ranging from unicellular alga to trees have been completely sequenced. As the transport of water, nutrients, hormones, and metabolites in aquatic plants could differ from that of non-vascular, vascular or flowering plants, this rich resource has the potential to answer many of our most urgent questions: How did specific transporters evol...

Peer-reviewed literature and published reports were used to summarize knowledge of benthic algal assemblage composition and ecology in Lake Erie, and causes and consequences of temporal variation in algal abundance. Macroalgal assemblages in rocky littoral and so— substrate habitats have been reasonably well described and studied, as has the epiphyte/ metaphyte assemblage associated with rocky ...
