Genome sequence of the ultrasmall unicellular red alga Cyanidioschyzon merolae 10D
The results indicate that the C. merolae genome provides a model system with a simple gene composition for studying the origin, evolution and fundamental mechanisms of eukaryotic cells.

The results indicate that plastid division involves the stepwise localization of FtsZ, PDV1, and ARC5 at the division site and that PDV 1 and PDV2 together mediate the recruitment of ARC5 to the midplastid constriction at a late stage of division.
Pollen Tube Attraction by the Synergid Cell
It is shown by laser cell ablation that two synergid cells adjacent to the egg cell attract the pollen tube, and a single synergid cell was sufficient to generate an attraction signal, and two cells enhanced it.
Genome Sequence of the Pea Aphid Acyrthosiphon pisum
The genome of the pea aphid shows remarkable levels of gene duplication and equally remarkable gene absences that shed light on aspects of aphid biology, most especially its symbiosis with Buchnera.
Identification of cyanobacterial cell division genes by comparative and mutational analyses
Comparisons and mutational analyses define more comprehensively the repertoire of genes involved in cyanobacterial cell division and suggest that cyanobacteria and Gram‐positive bacteria share specific division proteins.
The PLASTID DIVISION1 and 2 Components of the Chloroplast Division Machinery Determine the Rate of Chloroplast Division in Land Plant Cell Differentiation[C][W]
It is suggested that the integration of PDV proteins into the division machinery enabled land plant cells to change chloroplast size and number in accord with the fate of cell differentiation.
PARC6, a novel chloroplast division factor, influences FtsZ assembly and is required for recruitment of PDV1 during chloroplast division in Arabidopsis.
PARC6, an ARC6-like protein unique to vascular plants, fulfills the role of coordinating the internal and external components of the chloroplast division complex, but that PARC6 has evolved distinct functions in the division process.
Complete sequence and analysis of the plastid genome of the unicellular red alga Cyanidioschyzon merolae.
The phylogenetic results suggest that the Cyanidiophyceae, including C. merolae, are a basal clade within the red lineage plastids, and several genes that are rarely found in other plastid genomes are identified.
A Plant-Specific Dynamin-Related Protein Forms a Ring at the Chloroplast Division Site Article, publication date, and citation information can be found at www.plantcell.org/cgi/doi/10.1105/tpc.009373.
Results show that a dynamin-related protein also participates in chloroplast division and that its behavior differs from that of FtsZ and plastid-dividing rings that form before constriction at the site of division.
