Abstract
We favor a recent hypothesis that glaucocystophyte cyanelles as the closest cousins to cyanobacteria among plastids contain 'eukaryotic carboxysomes': bicarbonate enrichment within cyanelles should be considerably higher than in chloroplasts with their pyrenoid-based CCM. Thus, the stress-bearing fu...

Abstract
We explored the effects of a textile industry effluent on water quality, habitat quality and structural and functional responses of benthic communities in a lowland stream. Two sampling sites were selected: site 1 was located 300 m upstream of the outflow from the textile factory and site 2 was 500...

Abstract
The nature of the cytoplasmic pathway of starch biosynthesis was investigated in the model glaucophyte Cyanophora paradoxa. The storage polysaccharide granules are shown to be composed of both amylose and amylopectin fractions, with a chain length distribution and crystalline organization similar to...

Abstract
In this paper we present evidence for a dual location of the Sec translocon in the thylakoid as well as inner envelope membranes of the cyanelles from Cyanophora paradoxa, i. e. conservative sorting sensu stricto. The prerequisite was the generation of specific antisera directed against cyanelle Sec...

Abstract
We used immunofluorescence microscopy to observe the process of FtsZ ring formation, which is expected to lead cyanelle division, and demonstrated that an FtsZ arc and a split FtsZ ring emerge during the early and late stages of cyanelle division, respectively. We used an anti-FtsZ antibody to obser...

Abstract
We present physiological data in support of a CCM: CO(2) exchange activity as well as apparent affinity against inorganic carbon were found to increase under CO(2)-limiting stress. Further, expressed sequence tags (ESTs) of C. paradoxa were obtained from two cDNA libraries, one from cells grown in h...

Abstract
We assembled a multigene data set of conserved nuclear-encoded plastid-targeted proteins of cyanobacterial origin (i.e., through primary endosymbiotic gene transfer) from glaucophyte, red, and green (including land plants) algae to infer the branching order within this supergroup. We find strong sup...

Abstract
We established 12 new GPI sequences from rhodophytes, the glaucophyte Cyanophora paradoxa, a ciliate, and all orders of complex algae with red plastids (haptophytes, diatoms, cryptophytes, and dinoflagellates). Our comprehensive phylogenies do not support previous GPI-based speculations about a euka...

Abstract
We established 15 new sequences including three cDNA and twelve genomic clones with up to 24 introns per gene, which were identified in the GPI of Marchantia. The intron patterns of all six genes are completely conserved among seed plants, lycopods, mosses and even liverworts. This intron stasis wit...

Abstract
To further explore the initial mode of protein translocation, the observed phenylalanine dependence for protein translocation into glaucophyte plastids was pursued in detail. We document that indeed the phenylalanine has an impact on both, lipid binding and binding to proteoliposomes hosting an Omp8...

Abstract
We have assigned fractions Y2 and Y3 as inner and outer envelope membrane fractions of cyanelles, respectively. Protein compositions were rather different between the two envelope membranes indicating little cross-contamination among the fractions....

Current Biology (16)24 2006
Abstract
The nuclear genomes of photosynthetic eukaryotes are littered with genes derived from the cyanobacterial progenitor of modern-day plastids. A genomic analysis of Cyanophora paradoxa - a deeply diverged unicellular alga - suggests that the abundance and functional diversity of nucleus-encoded genes o...

Current Biology (16)23 2006
Abstract
We determine whether the level of cyanobacterial gene recruitment proposed for Arabidopsis is of the same magnitude in the algal sisters of plants by analyzing expressed-sequence tag (EST) data from the glaucophyte alga Cyanophora paradoxa. Bioinformatic analysis of 3,576 Cyanophora nuclear genes sh...

Abstract
We established GapA, GapB, and CP12 sequences from bryophytes, all orders of charophyte as well as chlorophyte green algae, and the glaucophyte Cyanophora paradoxa. Comprehensive phylogenetic analyses of all available plastid GAPDH sequences suggest that glaucophytes and green plants are sister line...

Plant Journal (44)4 2005
Abstract
We now demonstrate that heterologous precursors are readily imported into isolated cyanelles, provided that the essential phenylalanine residue is engineered into the N-terminal part of chloroplast transit peptides. The cyanelle and likely also the rhodoplast import apparatus can be envisaged as pro...

Current Biology (15)14 2005
Abstract
We present two phylogenomic analyses, with 50 genes from 16 plastid and 15 cyanobacterial genomes and with 143 nuclear genes from 34 eukaryotic species, respectively. The nuclear dataset includes new sequences from glaucophytes, the less-studied group of primary photosynthetic eukaryotes. We find si...

Abstract
We have identified a novel carotenoid-rich protein (CRP) in the glaucophyte Cyanophora paradoxa that is 28 kDa and immunologically related to the family of LHCs. CRP is associated with the thylakoid membrane, though it can be removed by stringent washes, suggesting that there are probably significan...

Molecular Membrane Biology (22)1-2 2005
Abstract
The cyanelles of the glaucocystophyte alga Cyanophora paradoxa resemble endosymbiotic cyanobacteria in morphology, pigmentation and, especially, in the presence of a peptidoglycan wall situated between the inner and outer envelope membranes. However, it is now clear that cyanelles in fact are primit...

Abstract
We have sampled various diverse protists to determine which groups have retained the gene. Database searches and degenerate PCR uncovered genes for likely mitochondrial FtsZs from the glaucocystophyte Cyanophora paradoxa, the oomycete Phytophthora infestans, two haptophyte algae, and two diatoms--on...

Abstract
We conclude that the catalytic deficiency is most likely due to the perturbation of the global structure of the plastid P RNAs compared to the bacterial counterpart. As a consequence, the plastid P RNAs are unable to bind to the precursor tRNA substrates. We discuss these results in the context of p...

Abstract
We report the sequence of apcC, specifying the precursor to the colorless polypeptide L(c)(7.8), the first core linker reported for a eukaryote. The precursor was efficiently imported in vitro into isolated cyanelles. Fractionation into thylakoid membranes and stroma and into intact phycobilisomes a...
