Identification of Plant-like Galactolipids in Chromera velia, a Photosynthetic Relative of Malaria Parasites*
Apicomplexa are protist parasites that include Plasmodium spp., the causative agents of malaria, and Toxoplasma gondii, responsible for toxoplasmosis. Most Apicomplexa possess a relict plastid, the apicoplast, which was acquired by secondary endosymbiosis of a red alga. Despite being nonphotosynthetic, the apicoplast is otherwise metabolically similar to algal and plant plastids and is essentia...
متن کاملMorphology and ultrastructure of multiple life cycle stages of the photosynthetic relative of apicomplexa, Chromera velia.
Chromera veliais a photosynthetic alga with a secondary plastid that represents the closest known photosynthetic relative of the apicomplexan parasites. The original description of this organism was based on brownish, immotile coccoid cells, which is the predominating stage ofC. veliain the culture. Here we provide a detailed light and electron microscopy description of coccoid cells ofC. velia...
متن کاملNonreductive iron uptake mechanism in the marine alveolate Chromera velia.
Chromera velia is a newly cultured photosynthetic marine alveolate. This microalga has a high iron requirement for respiration and photosynthesis, although its natural environment contains less than 1 nm of this metal. We found that this organism uses a novel mechanism of iron uptake, differing from the classic reductive and siderophore-mediated iron uptake systems characterized in the model ye...
متن کاملRed and Problematic Green Phylogenetic Signals among Thousands of Nuclear Genes from the Photosynthetic Apicomplexan Chromera velia
Among the 3151 Chromera EST-contigs that we recently published (Woehle et al. 2011; Genome Biol. Evol. 3:1220–1230) we have subsequently identified 113 sequences having very high nucleotide sequence identity ( 90%) to some higher eukaryote accessions, mainly Hordeum or Triticum, at the NCBI nucleotide database. These are almost certainly contaminations introduced at the commercial sequencing fa...
متن کاملRed and Problematic Green Phylogenetic Signals among Thousands of Nuclear Genes from the Photosynthetic and Apicomplexa-Related Chromera velia
The photosynthetic and basal apicomplexan Chromera velia was recently described, expanding the membership of this otherwise nonphotosynthetic group of parasite protists. Apicomplexans are alveolates with secondary plastids of red algal origin, but the evolutionary history of their nuclear genes is still actively discussed. Using deep sequencing of expressed genes, we investigated the phylogenet...
