The rice plastid genes psaA and psaB encoding the two apoproteins ofP700 chlorophyll a protein complex of photosystem I reac-tion center, and the putative rpsl4 gene for ribosomal protein Sl4, are organized into a transcription u it. Northern blot analyses revealed that the polycistronic mRNA is tra ..."

Genome Fragmentation Is Not Confined to the Peridinin Plastid in Dinoflagellates
"... When plastids are transferred between eukaryote lineages through series of endosymbiosis, their environment changes dramatically. Comparison of dinoflagellate plastids that originated from different algal groups has revealed convergent evolution, suggesting that the host environment mainly influence ..."

the mini-circles of the peridin-containing plastids, we have investigated its genome by in-depth sequencing using 454 pyrosequencing technology, PCR and clone library analysis. Sequence analyses show several genes with significantly higher copy numbers than present in the chromosome. These genes are most
Nuclear encoding of a plastid σ factor in rice and its tissue- and light-dependent expression
, 1997
"... DDBJ/EMBL/GenBank accession no. AB005290 A full-length cDNA encoding a putative σ factor for a plastid RNA polymerase was isolated from the higher plant Oryza sativa. The nucleotide sequence of the corresponding nuclear gene, named Os-sigA (O.sativa sigma A), predicts a polypeptide of 519 amino acid ..."

Genes of Cyanobacterial Origin in Plant Nuclear Genomes Point to a Heterocyst-Forming Plastid Ancestor
"... Plastids are descended from a cyanobacterial symbiosis which occurred over 1.2 billion years ago. During the course of endosymbiosis, most genes were lost from the cyanobacterium’s genome and many were relocated to the host nucleus through endosymbiotic gene transfer (EGT). The issue of how many gen ..."

Ectopic Overexpression of The Transcription Factor OsGLK1 Induces Chloroplast Development in Non-Green
"... For systematic and genome-wide analyses of rice gene functions, we took advantage of the full-length cDNA overexpresser (FOX) gene-hunting system and generated> 12 000 independent FOX-rice lines from> 25 000 rice calli treated with the rice-FOX Agrobacterium library. We found two FOX-rice line ..."

number of nucleus-encoded genes involved in chloroplast functions were highly expressed and transcripts of plastid-encoded genes, psaA, psbA and rbcL, increased in the OsGLK1-FOX calli. Transmission electron microscopy showed the existence of differentiated chloroplasts with grana stacks
Phylogenetic artifacts can be caused by leucine, serine, and arginine codon usage heterogeneity: dinoXagellate plastid origins as a case study

, 2004
"... Abstract.—Phylogenetic analyses of first and second codon positions (DNA1+2 analysis) and amino acid sequences (protein analysis) are often thought to provide similar estimates of deep-level phylogeny. However, here we report a novel artifact influencing DNA level phylogenetic inference of protein-c ..."

-coding genes introduced by codon usage heterogeneity that causes significant incongruities between DNA1+2 and protein analyses. DNA1+2 analyses of plastid-encoded psbA genes (encoding of photosystem II D1 proteins) strongly suggest a relationship between haptophyte plastids and typical (peridinin
1 Macroarray for studying chloroplast gene expression profiles associated with the initial development of wheat
"... Chloroplasts, as photosynthetic carbon assimilating organelles, play an essential role in plants throughout their development. We have previously devised a mitochondrial macroarray using a set of rice and wheat mitochondrial genes to study their expression associated with biogenesis and initial deve ..."

"... Abstract: We demonstrate the scarcity of conserved bacterial-type promoters in plastids of Streptophyta and report widely conserved promoters only for genes psaA, psbA, psbB, psbE, rbcL. Among the reasonable explanations are: evolutionary changes of sigma subunit paralogs and phage-type RNA polymera ..."
