Abstract
Chloroplast is a crucial organelle for plant photosynthesis and maintaining normal life activities in higher plants. Although some genes related to chloroplast development and pigment synthesis have been identified or cloned in rice, little is known about the relationship between these genes and abiotic stress response. In this study, we identified a novel mutant white stripe leaf 12 (wsl12) affecting pigment synthesis, chloroplast development and abiotic stress response in rice. The mutant phenotype was obvious at seeding and tillering stages and in response to the temperature change. Genetic analysis of reciprocal crosses between wsl12 and wild-type plants showed that wsl12 was a recessive mutant in a single nuclear locus. Map-based cloning revealed that the WSL12 locus encoded OsNDPK2, one of the three nucleoside diphosphate kinases (OsNDPKs). WSL12 expressed in all tested tissues, while it highly expressed in leaves and young tissues. The WSL12 protein localized to the chloroplast. The wsl12 mutant showed higher superoxide anion level and enhanced sensitivity to abscisic acid (ABA) and salinity. The transcription pattern of many genes involved in chlorophyll biosynthesis, ABA synthesis, light signaling pathway, reactive oxygen species-scavenging pathway and the other two OsNDPKs was altered in the wsl12 mutant. These results indicate that the OsNDPK2 encoded by WSL12 plays an important role in chloroplast development and chlorophyll biosynthesis by regulating the expression levels of related genes. In addition, WSL12 also affects the response to abiotic stress, such as ABA and salinity in rice, and is beneficial to molecular breeding of stress tolerance.

Abstract
This review describes the five nucleoside diphosphate kinase (NDPK) genes found in both model plants Arabidopsis thaliana (thale cress) and Oryza sativa L. (rice). Phylogenetic and sequence analyses of these genes allow the definition of four types of NDPK isoforms with different predicted subcellular localization. These predictions are supported by experimental evidence for most NDPK types. Data mining also provides evidence for the existence of a novel NDPK type putatively localized in the endoplasmic reticulum. Phylogenic analyses indicate that plant types I, II, and III belong to the previously identified Nme group I whereas type IV belongs to Nme group II. Additional analysis of the literature offers clues supporting the idea that the various plant NDPK types have different functions. Hence, cytosolic type I NDPKs are involved in metabolism, growth, and stress responses. Type II NDPKs are localized in the chloroplast and mainly involved in photosynthetic development and oxidative stress management. Type III NDPKs have dual targeting to the mitochondria and the chloroplast and are principally involved in energy metabolism. The subcellular localization and precise function of the novel type IV NDPKs, however, will require further investigations.

Abstract
Sugar metabolism is intricately connected with mitochondria through the conversion of sugars to ATP, and through the production of carbon skeletons that can be used in anabolic processes. Sugar molecules also take part in signalling cascades. In this study we investigated the impact of sucrose on the expression of the Arabidopsis thaliana Nucleoside Diphosphate Kinase gene family (NDPK, EC 2.7.4.6), focusing on NDPK3a, the product of which is located predominantly in mitochondria. Using quantitative PCR we show that the NDPK3a gene is subject to sucrose and glucose induction, while no other Arabidopsis NDPK gene are sucrose-inducible. The induction reaches a half-maximum after about 6 hours and is stable for at least 48 h. Sucrose and glucose inductions were found not to be affected by the presence of a hexokinase inhibitor, N-acetyl-glucosamine. Furthermore, turanose, a sucrose analogue that is not metabolised in plant cells, did not induce NDPK3a gene expression. An analysis of the NDPK3a gene revealed two WBOXHWISO1 boxes in the promoter region, elements that have previously been reported to be involved in sugar signalling in barley via the SUSIBA2 protein. SUSIBA2 belongs to the WRKY group of transcription factors. In this study we used two mutants containing T-DNA insertions in WRKY-genes, AtWrky4 and AtWrky34, to investigate the possible involvement of WRKY transcription factors in the sugar induction of NDPK3a.

Abstract
Phytochromes are light responsive photoreceptors in plants that influence development and differentiation during the entire plant life cycle. Plant nucleoside diphosphate kinase 2 (NDPK2) has been reported to be a component of the light-mediated signalling cascade and to interact physically with phytochrome A in the cytosol. By using diverse methods as in vitro imports, in vivo localisation of GFP-fusion proteins and immuno blotting of plant cell fractions we clearly localise NDPK2 only to chloroplasts but not to the cytosol, demonstrating that although high affinity protein-protein interactions can occur in vitro, their physiological relevance can be artificial if the proteins are localised to different cell compartments in vivo.

Abstract
Here, we present the characterization of a plant NDPK exhibiting nuclease activity. This is the first identification of a nuclease localised in the intermembrane space of plant mitochondria. The recombinant pea NDPK3 protein cleaves not only supercoiled plasmid DNA, but also highly structured RNA molecules such as tRNAs or the 3'UTR of the atp9 mRNA suggesting that the NDPK3 nuclease activity has a structural requirement. ATP inhibits this nuclease activity, while ADP has no effect. Furthermore, studies on NDPK mutant proteins indicate that the nuclease- and the kinase-mechanisms are separate.

Abstract
A cDNA encoding Solanum chacoense cytosolic NDPK (NDPK1, EC 2.7.4.6) was isolated. The open reading frame encoded a 148 amino acid protein that shares homology with other cytosolic NDPKs including a conserved N-terminal domain. S. chacoense NDPK1 was expressed in Escherichia coli as a 6xHis-tagged protein and purified by affinity chromatography. The recombinant protein exhibited a pattern of abortive complex formation suggesting that the enzyme is strongly regulated by the NTP/NDP ratio. A polyclonal antibody generated against recombinant NDPK1 was specific for the cytosolic isoform in Solanum tuberosum as shown from immunoprecipitation experiments and immunoblot analysis of chloroplasts and mitochondria preparations. NDPK activity and NDPK1 protein were found at different levels in various vegetative and reproductive tissues. DEAE fractogel analyses of NDPK activity in root tips, leaves, tubers and cell cultures suggest that NDPK1 constitutes the bulk of extractable NDPK activity in all these organs. NDPK activity and NDPK1 protein levels raised during the exponential growth phase of potato cell cultures whereas no rise in activity or NDPK1 protein was observed when sucrose concentration in the culture was manipulated to limit growth. Activity measurements, immunoblot analysis as well as immunolocalization experiments performed on potato root tips and shoot apical buds demonstrated that NDPK1 was predominantly localized in the meristematic zones and provascular tissues of the apical regions. These data suggest that NDPK1 plays a specific role in the supply of UTP during early growth of plant meristematic and provascular tissues.

Abstract
This study presents an analysis of the stromal proteome in its oligomeric state extracted from highly purified chloroplasts of Arabidopsis thaliana. 241 proteins (88% with predicted cTP), mostly assembled in oligomeric complexes, were identified by mass spectrometry with emphasis on distinguishing between paralogues. This is critical because different paralogues in a gene family often have different subcellular localizations and/or different expression patterns and functions. The native protein masses were determined for all identified proteins. Comparison with the few well characterized stromal complexes from A. thaliana confirmed the accuracy of the native mass determination, and by extension, the usefulness of the native mass data for future in-depth protein interaction studies. Resolved protein interactions are discussed and compared with an extensive collection of native mass data of orthologues in other plants and bacteria. Relative protein expression levels were estimated from spot intensities and also provided estimates of relative concentrations of individual proteins. No such quantification has been reported so far. Surprisingly proteins dedicated to chloroplast protein synthesis, biogenesis, and fate represented nearly 10% of the total stroma protein mass. Oxidative pentose phosphate pathway, glycolysis, and Calvin cycle represented together about 75%, nitrogen assimilation represented 5-7%, and all other pathways such as biosynthesis of e.g. fatty acids, amino acids, nucleotides, tetrapyrroles, and vitamins B(1) and B(2) each represented less than 1% of total protein mass. Several proteins with diverse functions outside primary carbon metabolism, such as the isomerase ROC4, lipoxygenase 2 involved in jasmonic acid biosynthesis, and a carbonic anhydrase (CA1), were surprisingly abundant in the range of 0.75-1.5% of the total stromal mass. Native images with associated information are available via the Plastid Proteome Database.

Abstract
The apparatus of photosynthetic energy conversion in chloroplasts is quite well characterized with respect to structure and function. Light-driven electron transport in the thylakoid membrane is coupled to synthesis of ATP, used to drive energy-dependent metabolic processes in the stroma and the outer surface of the thylakoid membrane. The role of the inner (luminal) compartment of the thylakoids has, however, remained largely unknown although recent proteomic analyses have revealed the presence of up to 80 different proteins. Further, there are no reports concerning the presence of nucleotides in the thylakoid lumen. Here, we bring three lines of experimental evidence for nucleotide-dependent processes in this chloroplast compartment. (i) The thylakoid lumen contains a protein of 17.2 kDa, catalyzing the transfer of the gamma-phosphate group from ATP to GDP, proposed to correspond to the nucleoside diphosphate kinase III. (ii) The 33-kDa subunit of photosystem II, bound to the luminal side of the thylakoid membrane and associated with the water-splitting process, can bind GTP. (iii) The thylakoid membrane contains a nucleotide transport system that is suggested to be associated with a 36.5-kDa nucleotide-binding protein. Our results imply, against current dogmas, that the thylakoid lumen contains nucleotides, thereby providing unexpected aspects on this chloroplast compartment from a metabolic and regulatory perspective and expanding its functional significance beyond a pure bioenergetic function.

Abstract
In this work we have further characterized the first mitochondrial nucleoside diphosphate kinase (mtNDPK) isolated from plants. The mitochondrial isoform was found to be especially abundant in reproductive and young tissues. Expression of the pea (Pisum sativum L. cv Oregon sugarpod) mtNDPK was not affected by different stress conditions. However, the pea mtNDPK was found to interact with a novel 86-kD protein, which is de novo synthesized in pea leaves upon exposure to heat. Thus, we have evidence for the involvement of mtNDPK in mitochondrial heat response in pea in vivo. Studies on oligomerization revealed that mtNDPK was found in complexes of various sizes, corresponding to the sizes of e.g. hexamers, tetramers, and dimers, indicating flexibility in oligomerization. This flexibility, also found for other NDPK isoforms, has been correlated with the ability of this enzyme to interact with other proteins. We believe that the mtNDPK is involved in heat stress response in pea, possibly as a modulator of the 86-kD protein.

Abstract
Nucleoside (NDP) diphosphate kinases are oligomeric enzymes. Most are hexameric, but some bacterial enzymes are tetrameric. Hexamers and tetramers are constructed by assembling identical dimers. The hexameric structure is important for protein stability, as demonstrated by studies with natural mutants (the Killer-of-prune mutant of Drosophila NDP kinase and the S120G mutant of the human NDP kinase A in neuroblastomas) and with mutants obtained by site-directed mutagenesis. It is also essential for enzymic activity. The function of the tetrameric structure is unclear.

Abstract
For the first time, to our knowledge, a nucleoside diphosphate kinase (NDPK) has been purified from plant mitochondria (Pisum sativum L.). In intact pea leaf mitochondria, a 17.4-kDa soluble protein was phosphorylated in the presence of EDTA when [gamma-32P]ATP was used as the phosphate donor. Cell fractionation demonstrated that the 17.4-kDa protein is a true mitochondrial protein, and the lack of accessibility to EDTA of the matrix compartment in intact mitochondria suggested it may have an intermembrane space localization. The 17.4-kDa protein was purified from mitochondrial soluble proteins using ATP-agarose and anion exchange chromatography. Amino-acid sequencing of two peptides, resulting from a trypsin digestion, revealed high similarity with the conserved catalytic phosphohistidine site and with the C-terminal of NDPKs. Acid and alkali treatments of [32P]-labelled pea mitochondrial NDPK indicated the presence of acid-stable as well as alkali-stable phosphogroups. Thin-layer chromatography experiments revealed serine as the acid-stable phosphogroup. The alkali-stable labelling probably reflects phosphorylation of the conserved catalytic histidine residue. In phosphorylation experiments, the purified pea mitochondrial NDPK was labelled more heavily on serine than histidine residues. Furthermore, kinetic studies showed a faster phosphorylation rate for serine compared to histidine. Both ATP and GTP could be used as phosphate donor for histidine as well as serine labelling of the pea mitochondrial NDPK.

Abstract
Nucleoside diphosphate kinases (NDPKs) catalyse the phosphorylation of nucleoside diphosphates. In mammals, the functional enzyme is a hexamer composed of different amounts of two homologous acidic (A) and basic (B) subunits encoded by separate genes. In prokaryotes and invertebrate eukaryotes, only one cytoplasmic enzyme has been isolated. Other genes encoding chloroplastic and mitochondrial forms as well as related proteins have been cloned. Here, we show that in Xenopus laevis, as in mammals, the cytoplasmic NDPK is encoded by several homologous genes. With Xenopus laevis being a pseudotetraploid species, each monomer is encoded by two genes. The amino acid sequences are very similar, and all the differences concern amino acids located at the outer surface of the hexameric enzyme. The Xenopus genes share 82-87% identity with their human counterparts. Interestingly, in vitro, the Xenopus X1 enzyme binds to a specific nuclease hypersensitive element (NHE) of the human c-myc promoter, as does its human counterpart. X1 also binds to a single-stranded (CT)(n) dinucleotide repeat. The NHE is present in the coding strand of a pyrimidine-rich region of the 3' non-coding sequence of the Xenopus NDPK genes. We propose that NDPK is indeed able to bind to its own mRNA and prevent polyadenylation at the normal position. This could provide an autoregulatory translation mechanism. A phylogenetic tree of the vertebrate NDPK sequences supports the idea that in amphibians, as in mammals, gene duplication has resulted in functional diversification.
