Abstract The importance of 'eco-evolutionary feedbacks' in natural systems is currently unclear. Here, we advance a general hypothesis for a particular class of eco-evolutionary feedbacks with potentially large, long-lasting impacts in complex ecosystems. These eco-evolutionary feedbacks involve traits that mediate important interactions with abiotic and biotic features of the environment and a self-driven reversal of selection as the ecological impact of the trait varies between private (small ...

Organelle retention is a form of mixotrophy that allows organisms to reap metabolic benefits similar to those of photoautotrophs through capture of algal prey and sequestration of their plastids. Mesodinium rubrum is an abundant and broadly distributed photosynthetic marine ciliate that steals organelles from cryptophyte algae, such as Geminigera cryophila. M. rubrum is unique from most other acquired phototrophs because it also steals a functional nucleus that facilitates genetic control of seq...

A striking property of the mutualism between figs and their pollinating wasps is that wasps consistently oviposit in the inner flowers of the fig syconium, which develop into galls that house developing larvae. Wasps typically do not use the outer ring of flowers, which develop into seeds. To better understand differences between gall and seed flowers, we used a metatranscriptomic approach to analyze eukaryotic gene expression within fig flowers at the time of oviposition choice and early gall d...

Abstract Phylomes (comprehensive sets of gene phylogenies for organisms) are built to investigate fundamental questions in genomics and evolutionary biology, such as those pertaining to the detection and characterization of horizontal gene transfer in microbes. To address these questions, phylome construction demands rigorous yet efficient phylogenetic methods. Currently, many sequence alignment and tree-building models can analyze several thousands of genes in a high-throughput manner. However,...

The dinoflagellates are an evolutionarily and ecologically important group of microbial eukaryotes. Previous work suggests that horizontal gene transfer (HGT) is an important source of gene innovation in these organisms. However, dinoflagellate genomes are notoriously large and complex, making genomic investigation of this phenomenon impractical with currently available sequencing technology. Fortunately, de novo transcriptome sequencing and assembly provides an alternative approach for investig...

Dinoflagellates produce a variety of toxic secondary metabolites that have a significant impact on marine ecosystems and fisheries. Saxitoxin (STX), the cause of paralytic shellfish poisoning, is produced by three marine dinoflagellate genera and is also made by some freshwater cyanobacteria. Genes involved in STX synthesis have been identified in cyanobacteria but are yet to be reported in the massive genomes of dinoflagellates. We have assembled comprehensive transcriptome data sets for severa...

Many microbes cooperatively secrete extracellular products that favorably modify their environment. Consistent with social evolution theory, structured habitats play a role in maintaining these traits in microbial model systems, by localizing the benefits and separating strains that invest in these products from ‘cheater’ strains that benefit without paying the cost. It is thus surprising that many unicellular, well-mixed microalgal populations invest in extracellular toxins that confer ecologic...

Background: Microalgae hold promise for yielding a biofuel feedstock that is sustainable, carbon-neutral, distributed, and only minimally disruptive for the production of food and feed by traditional agriculture. Amongst oleaginous eukaryotic algae, the B race of Botryococcus braunii is unique in that it produces large amounts of liquid hydrocarbons of terpenoid origin. These are comparable to fossil crude oil, and are sequestered outside the cells in a communal extracellular polymeric matrix ma...

Microbial eukaryotes may extinguish much of their nuclear phylogenetic history due to endosymbiotic/horizontal gene transfer (E/HGT). We studied E/HGT in 32,110 contigs of expressed sequence tags (ESTs) from the dinoflagellate Alexandrium tamarense (Dinophyceae) using a conservative phylogenomic approach. The vast majority of predicted proteins (86.4%) in this alga are novel or dinoflagellate-specific. We searched for putative homologs of these predicted proteins against a taxonomically broadly ...

The dinoflagellates are an ecologically important group of microbial eukaryotes that have evolved many novel genomic characteristics. They possess some of the largest nuclear genomes among eukaryotes arranged on permanently condensed liquid-crystalline chromosomes. Recent advances have revealed the presence of genes arranged in tandem arrays, trans-splicing of messenger RNAs, and a reduced role for transcriptional regulation compared to other eukaryotes. In contrast, the mitochondrial and plasti...
