Green) Research priorities MO is currently working on the evolution of secondary endosymbiosis. Many unicellular photoautotrophic eukaryotes (such as diatoms, heterokonts, cryptophytes, haptophytes, euglenoids) possess complex photosynthetic organelles that evolved during the process of secondary endosymbiogenesis. Such secondary (or complex) plastids are surrounded by three or four membranes. Nuclear-encoded proteins are postraslationally imported into the complex plastid via secretory pathway. We have participated on the annotation of the genome of diatom Thalassiosira pseudonana , particularly on the search of nuclear-encoded plastid targeted proteins, their in silico localization and phylogeny. Complex plastid is also present in apicomplexan parasites, however, it is not photosynthetic in this case. The size of the apicomplexan plastid genome is extremely small (35 kb) thus offering a limited number of genes for phylogenetic analysis. Moreover, the sequences of apicoplast genes are highly AT rich and rapidly evolving. Although it is evident that the apicoplast and its genome is plastid-derived, our detailed phylogenetic analysis of amino acid and nucleotide sequences of selected apicoplast ribosomal protein genes rpl2 , rpl14 and rps12 show their possible mitochondrial origin. Based on our results, a hypothesis is proposed that apicoplasts might contain both plastid and mitochondrial genes, thus constituting a hybrid assembly. MO is also involved in phylogenetic projets concerning molecular phylogeny of protozoa, e.g. microsporidia, apicomplexan parasites and kinteoplastids.
