Are algal genes in nonphotosynthetic protists evidence of historical plastid endosymbioses?
18 Oct 2009 
BACKGROUND: How photosynthetic organelles, or plastids, were acquired by diverse eukaryotes is among the most hotly debated topics in broad scale eukaryotic evolution. The history of plastid endosymbioses commonly is interpreted under the ...

14 Oct 2009 BACKGROUND: Heterokont algae, together with cryptophytes, haptophytes and some alveolates, possess red-algal derived plastids. The chromalveolate hypothesis proposes that the red-algal derived plastids of all four groups have a monophyletic origin ...

6 Oct 2009 BACKGROUND: Single- and low- copy genes are less likely subject to concerted evolution, thus making themselves ideal tools for studying the origin and evolution of polyploid taxa. Leymus is a polyploid genus with a diverse array of morphology, ...

The plant endoplasmic reticulum: a cell-wide web.
23 Sep 2009 The ER (endoplasmic reticulum) in higher plants forms a pleomorphic web of membrane tubules and small cisternae that pervade the cytoplasm, but in particular form a polygonal network at the cortex of the cell which may be anchored to the plasma ...

8 Sep 2009 Since its endosymbiotic beginning, the chloroplast has become fully integrated into the biology of the host eukaryotic cell. The exchange of genetic information from the chloroplast to the nucleus has resulted in considerable co-ordination in the ...

7 Sep 2009 Pentatricopeptide repeat (PPR) proteins constitute a large family in land plants and are required for various post-transcriptional steps associated with RNA in plant organelles. The moss Physcomitrella patens PPR protein, PpPPR_38, is a ...

Toxoplasma gondii: a simple Real-time PCR assay to quantify the proliferation of the apicoplast.
27 Aug 2009 A Real-time quantitative PCR assay to quantify the Toxoplasma gondii apicoplast was studied. Primers were designed to amplify a 305bp product specific to T. gondii apicoplast. Standard curves were generated for both T. gondii apicoplast DNA and ...

Function and biogenesis of iron-sulphur proteins.
11 Aug 2009 Iron-sulphur (Fe-S) clusters have long been recognized as essential and versatile cofactors of proteins involved in catalysis, electron transport and sensing of ambient conditions. Despite the relative simplicity of Fe-S clusters in terms of ...

Cyanobacterial contribution to the genomes of the plastid-lacking protists.
9 Aug 2009 BACKGROUND: Eukaryotic genes with cyanobacterial ancestry in plastid-lacking protists have been regarded as important evolutionary markers implicating the presence of plastids in the early evolution of eukaryotes. Although recent genomic surveys ...

4 Aug 2009 Unlike other oilseeds (e.g. Arabidopsis), developing sunflower seeds do not accumulate a lot of starch and they rely on the sucrose that comes from the mother plant to synthesise lipid precursors. Between 10 and 25 days after flowering (DAF), when ...
