Draft Genome Sequence of the Sexually Transmitted Pathogen Trichomonas vaginalis
The genome sequence of the protist Trichomonas vaginalis predicts previously unknown functions for the hydrogenosome, which support a common evolutionary origin of this unusual organelle with mitochondria.
A photosynthetic alveolate closely related to apicomplexan parasites
This corrects the article to say that the author of the paper is a post-graduate student at the Massachusetts Institute of Technology (MIT) and the article was originally written by a PhD student.
Functional and Evolutionary Insights from the Genomes of Three Parasitoid Nasonia Species
Key findings include the identification of a functional DNA methylation tool kit; hymenopteran-specific genes including diverse venoms; lateral gene transfers among Pox viruses, Wolbachia, and Nasonia; and the rapid evolution of genes involved in nuclear-mitochondrial interactions that are implicated in speciation.
Microsporidia are related to Fungi: evidence from the largest subunit of RNA polymerase II and other proteins.

Phylogenetic analyses of RPB1 sequences strongly support the notion that Microsporidia are not early-diverging eukaryotes but instead are specifically related to Fungi, and reexamination of elongation factors EF-1alpha and EF-2 sequence data show support for an early (Archezoan) divergence of these amitochondriate protists to be weak and likely caused by artifacts in phylogenetic analyses.

An Expanded Inventory of Conserved Meiotic Genes Provides Evidence for Sex in Trichomonas vaginalis
The analyses indicate that these meiotic genes arose, or were already present, early in eukaryotic evolution; thus, the eUKaryotic cenancestor contained most or all components of this set and was likely capable of performing meiotic recombination using near-universal meiotic machinery.
Signs of sex: what we know and how we know it.
Identification of Two Proteins Required for Conjunction and Regular Segregation of Achiasmate Homologs in Drosophila Male Meiosis
Using a meiosis detection toolkit to investigate ancient asexual "scandals" and the evolution of sex.
A "meiosis detection toolkit", a set of meiotic genes that represent the best markers for the presence of meiosis that will help to understand both meiotic gene evolution and the capacity for meiosis and sex in putative obligate asexuals.
