This paper presents the first full DNA sequence of a nucleomorph genome (that of the cryptomonad G. theta), the smallest nuclear genome completely sequenced. It shows that most nucleomorph genes are genetic housekeeping genes that are needed only to enable the expression of the 30 nucleomorph-encoded chloroplast protein genes and a handful of other end-product genes, notably a few transporter proteins.

This is an excellent review of protein targeting and import into chromalveolate and cabozoan chloroplasts. The term 'complex plastids', however, is misleading (except, perhaps, for dinoflagellates and euglenoids, which have triple chloroplast envelopes), because in chromists, Sporozoa and chlorarachneans, the two additional membranes (the periplastid membrane and either the epiplastid membrane or the perichloroplast rough ER) are neither evolutionarily nor cytologically chloroplast envelope membranes, but entirely distinct, additional structures that are not part of the chloroplasts themselves.

    • Chloroplast protein and centrosomal genes, a tRNA intron, and odd telomeres in an unusually compact eukaryotic genome, the cryptomonad nucleomorph
    • Zauner S, Fraunholz M, Wastl J, Penny S, Beaton M, Cavalier-Smith T, Maier UG, Douglas S: Chloroplast protein and centrosomal genes, a tRNA intron, and odd telomeres in an unusually compact eukaryotic genome, the cryptomonad nucleomorph. Proc Natl Acad Sci USA 2000, 97:200-205. Together with [5], this paper provides evidence for several centrosomal proteins encoded by the cryptomonad nucleomorph, making it highly probable that it divides mitotically. This is even though the authors of [12,13] could not detect microtubules ultrastructurally within dividing nuclei, in which the envelope does not break down (that is, nucleomorphs probably use closed mitosis like some red algae). This paper shows that the telomere sequences are less typical than in chlorarachnean nucleomorphs.

    • Evidence for nucleomorph to host nucleus gene transfer: Light-harvesting complex proteins from cryptomonads and chlorarachniophytes
    • Deane JA, Fraunholz M, Su V, Maier UG, Martin W, Durnford DG, McFadden GI: Evidence for nucleomorph to host nucleus gene transfer: light-harvesting complex proteins from cryptomonads and chlorarachniophytes. Protist 2000, 151:239-252. It had long been deduced that hundreds, possibly thousands, of genes must have been transferred from nucleomorphs into the host nucleus. The light-harvesting complex (LHC) proteins are the first well-studied example. The bipartite cryptomonad targeting sequences are more similar to those of heterokonts than alveolates, supporting chromist monophyly. This study provides the first evidence for bipartite targeting sequences in chlorarachneans and suggests that their LHC protein is more similar to that of Tetraselmis than those of higher plants, corroborating other evidence that both chlorarachnean and euglenoid plastids came from a green alga belonging to the infraphylum Tetraphytae, which includes Tetraselmis, Ulvophyceae, Trebouxiophyceae and Chlorophyceae [4].

    • A cyanobacterial gene in nonphotosynthetic protists - An early chloroplast acquisition in eukaryotes?
    • Andersson JO, Roger AJ: A cyanobacterial gene in nonphotosynthetic protists - An early chloroplast acquisition in eukaryotes? Curr Biol 2002, 12:115-119. The presence of a cyanobacterium-/plastid-related gene (gnd) for 6-phosphogluconate dehydrogenase (the second enzyme in the oxidative pentose phosphate pathway) shows that Percolozoa and oomycetes arose from algal ancestors, as argued by the cabozoan and chromalveolate theories, respectively. Although the trypanosome gnd gene is so divergent that its ancestry is unclear, the simplest view is that it was present in a common photosynthetic ancestor of all discicristate protozoa; even the more divergent gnd genes of Metamonada might have come from a common ancestral photosynthetic excavate [43•]. Although these data imply that plastids were present much earlier in excavate evolution than often assumed, they do not distinguish between acquisition of the gnd gene by secondary symbiogenesis (the cabozoan theory) and the less parsimonious idea that the primary origin of chloroplasts took place in a common ancestor of plants and excavates such as discicristates.

This paper provides the strongest evidence yet for chromalvealate monophyly and their common ancestral origin by a single symbiogenetic enslavement of a red alga. The red algal plastid glyceraldehyde phosphate dehydrogenase has been replaced in chromalveolates by a duplicate of the cytosolic version that acquired bipartite amino-terminal targeting sequences for import into plastids from the cytosol. This version is clearly related to the cytosolic one of ciliates, alveolates that, before the chromalveolate theory, had been assumed not to have had a photosynthetic ancestor. It is highly improbable that an identical gene duplication, retargeting and gene replacement occurred independently in all four major chromalveolate groups (cryptomonads, chromobiotes, dinoflagellates and Sporozoa), as theories of separate secondary origins of each plastid type must assume.

    • The structure and gene repertoire of an ancient red algal plastid genome
    • Glockner G, Rosenthal A, Valentin K: The structure and gene repertoire of an ancient red algal plastid genome. J Mol Evol 2000, 51:382-390. This paper shows unique features of the Cyanidium chloroplast genome that are not shared with that of other red algae or chromalveolates. It supports the idea that Cyanidiophyceae should be a distinct red algal class and that the primary divergence within red algae was between them and the other unicellular class, Rhodellophyceae [4]. It also indicates that the red alga enslaved by the ancestral chromalveolate to form the cryptomonad nucleomorph and periplastid membrane was not derived from a cyanidiophyte, but from a more typical rhodellophyte red alga.

    • The phagotrophic origin of eukaryotes and phylogenetic classification of Protozoa
    • Cavalier-Smith T: The phagotrophic origin of eukaryotes and phylogenetic classification of Protozoa. Int J Syst Evol Microbiol 2002, 52:297-354. This paper revises the phagotrophy theory of the origin of eukaryotes in the light of evidence that no extant eukaryotes are primitively amitochondrial. It revises protozoan higher classification, formally establishing the new infrakingdoms Rhizaria and Excavata, and expanding the phylum Cercozoa (to which Chlorarachnea belong) by including the parasitic Ascetosporea. It names the ancestrally biciliate bikont clade, which includes plants, chromaIveolates, excavates and Rhizaria, arguing that their complex ciliary transformation indicates that they are derived compared with the putatively primitively uniciliate Amoebozoa and opisthokonts.

    • Rooting the eukaryote tree by using a derived gene fusion
    • Stechmann A, Cavalier-Smith T: Rooting the eukaryote tree by using a derived gene fusion. Science 2002, 297:89-91. This paper shows that a secondarily derived gene fusion between dihydrofolate reductase and thymidylate synthetase (TS) is present in all bikont eukaryotes so far studied. If this gene fusion has never been reversed, the eukaryotic root must lie between bikonts (plants, chromalveolates, cabozoa, Heliozoa and Apusozoa) and opisthokonts (animals, choanozoan protozoa and fungi), which lack the fusion. The position of Amoebozoa with respect to the root remains ambiguous because it is unknown whether TS genes arnplified from them are truly separate or part of a fusion gene that simply would not amplify. As previous deductions of the position of the root using outgroup rooting of sequence trees were flawed by long-branch artefacts, this is the strongest available evidence regarding its true position.

    • Retortamonad flagellates are closely related to diplomonads - Implications for the history of mitochondrial function in eukaryote evolution
    • Silberman JD, Simpson AG, Kulda J, Cepicka I, Hampl V, Johnson PJ, Roger AJ: Retortamonad flagellates are closely related to diplomonads - Implications for the history of mitochondrial function in eukaryote evolution. Mol Biol Evol 2002, 19:777-786. This paper provides the first rRNA sequence evidence for the position of retortamonads, showing that they are either sisters of or derived from diplomonads. This supports the monophyly of the protozoan superclass Eopharyngia (diplomonads plus retortamonads) [4] and means that, like all other established groups of amitochondrial eukaryotes, they must be secondarily amitochondrial. Thus, no amitochondrial eukaryotes are primitive.
