    ABSTRACT: Protein ubiquitination in plant plays critical roles in many biological processes, including adaptation to abiotic stresses. Previously, Ring finger E3 Ligase has been characterized during salt stress response in several plant species, but little is known about its function in tomato. Here, we report that SpRing, a stress-inducible gene, is involved in salt stress signaling in wild tomato species Solanum pimpinellifolium “PI365967”. In vitro ubiquitination assay revealed that SpRing is an E3 ubiquitin ligase and the RING finger conserved region is required for its activity. SpRing is expressed in all tissues of wild tomato and upregulated by salt, drought and osmotic stresses, but repressed by low temperature. GFP fusion analysis showed that SpRing is localized at endoplasmic reticulum. Silencing of SpRing through virus-induced gene silencing approach led to increased sensitivity to salt stress in wild tomato. Over-expression of SpRing in Arabidopsis thaliana resulted in enhanced salt tolerance during seed germination and early seedling development. The expression levels of certain key stress-related genes are altered both in SpRing over-expression Arabidopsis plants and virus-induced gene silenced tomato seedlings. Taken together, our results indicate that SpRing is involved in salt stress and functions as a positive regulator of salt tolerance.

    ABSTRACT: Redox-regulation is an essential post-translational regulatory mechanism in Prokaryotes and Eukaryotes. The reversible oxidation and reduction of cysteine residues of proteins is also important in photosynthetic organisms to control enzymatic activities, protein stability and the interaction with other proteins of chloroplast-localized proteins. Several enzymes of the plant tetrapyrrole biosynthesis pathway have been identified to be redox-regulated by thioredoxins (TRXs) and NADPH-dependent thioredoxin reductase C (NTRC). Among those proteins Mg-protoporphyrin IX methyltransferase (encoded by CHLM) was identified to be activated and stabilized by interaction with NTRC. CHLM catalyses a methyl-group transfer by using S-adenosyl methionine (SAM). Here we demonstrate that three conserved cysteine residues of Arabidopsis CHLM are essential for catalytic function and redox-dependent activation of the enzyme. In vitro and in planta biochemical assays of recombinant CHLM and the Arabidopsis chlm knockout mutant overexpressing wild-type and cysteine substitution mutants of CHLM revealed modified methyltransferase activity, when the conserved cysteine residues of CHLM are replaced by serine. While C177 is responsible for redox-dependent enzyme activation, exchange of the two cysteine residues C111 and C115 has a strong impact on enzyme activity. The modified CHLM activity of single and double mutants with cysteine substitution is presented and the role of each cysteine residue is discussed based on a modelled structure of CHLM. These studies contribute to enhanced understanding of the physiological and enzymatic significance of redox-regulated CHLM.

    ABSTRACT: Magnesium (Mg) is an essential macronutrient, functioning as both a cofactor of many enzymes and as a component of Chl. Mg is abundant in plants; however, further investigation of the Mg transporters involved in Mg uptake and distribution is needed. Here, we isolated an Arabidopsis thaliana mutant sensitive to high calcium (Ca) conditions without Mg supplementation. The causal gene of the mutant encodes MRS2-4, an Mg transporter. MRS2-4 single mutants exhibited growth defects under low Mg conditions, whereas an MRS2-4 and MRS2-7 double mutant exhibited growth defects even under normal Mg concentrations. Under normal Mg conditions, the Mg concentration of the MRS2-4 mutant was lower than that of the wild type. The transcriptome profiles of mrs2-4-1 mutants under normal conditions were similar to those of wild-type plants grown under low Mg conditions. In addition, both mrs2-4 and mrs2-7 mutants were sensitive to high levels of Mg. These results indicate that both MRS2-4 and MRS2-7 are essential for Mg homeostasis, even under normal and high Mg conditions. MRS2-4–green fluorescent protein (GFP) was mainly detected in the endoplasmic reticulum. These results indicate that these two MRS2 transporter genes are essential for the ability to adapt to a wide range of environmental Mg concentrations.

    ABSTRACT: Glutathione (GSH) plays multiple roles in plants, including stress defense and growth/developmental regulation. Previous studies have demonstrated that ascorbate (AsA) redox state is involved in flowering initiation in Oncidium orchid. In this study, we discovered that a significantly decreased GSH content and GSH redox ratio are correlated with a decline in AsA redox state during flowering initiation and high ambient temperature-induced flowering. At the same time, the expression level and enzymatic activity of GSH redox-regulated genes, glutathione reductase (GR1), and the GSH biosynthesis genes γ-glutamylcysteine synthetase (GSH1) and glutathione synthase (GSH2), are down-regulated. Elevating dehydroascorbate (DHA) content in Oncidium by artificial addition of DHA resulted in the decreased AsA and GSH redox ratio, and enhanced dehydroascorbate reductase (DHAR) activity. This demonstrated that the lower GSH redox state could be influenced by the lower AsA redox ratio. Moreover, exogenous application of buthionine sulphoximine (BSO), to inhibit GSH biosynthesis, and glutathione disulfide (GSSG), to decrease GSH redox ratio, also caused early flowering. However, spraying plants with GSH increased GSH redox ratio and delayed flowering. Furthermore, transgenic Arabidopsis overexpressing Oncidium GSH1, GSH2, and GR1 displayed high GSH redox ratio as well as delayed flowering under high ambient temperature treatment, while pad2 and cad2, and gr1 mutants exhibited early flowering and low GSH redox ratio. In conclusion, our results provide evidence that the decreased GSH redox state is linked with the decline in AsA redox ratio and mediated by down-regulated expression of GSH metabolism-related genes to affect flowering time in Oncidium orchid.

    ABSTRACT: Plant cell morphogenesis involves concerted rearrangements of microtubules and actin microfilaments. We previously reported that FH1, the main housekeeping Arabidopsis thaliana Class I membrane-anchored formin, contributes to actin dynamics and microtubule stability in rhizodermis cells. Here we examine effects of mutations affecting FH1 (At3g25500) on cell morphogenesis and above-ground organ development in seedlings, as well as on cytoskeletal organization and dynamics, using a combination of confocal and variable angle epifluorescence microscopy with a pharmacological approach. Homozygous fh1 mutants exhibited cotyledon epinasty and had larger cotyledon pavement cells with more pronounced lobes than the wild type. The pavement cell shape alterations were enhanced by expression of the fluorescent microtubule marker GFP-MAP4. Mutant cotyledon pavement cells exhibited reduced density and increased stability of microfilament bundles, as well as enhanced dynamics of microtubules. Analogous results were obtained also upon treatments with the formin inhibitor SMIFH2. Pavement cell shape in wt and fh1 plants in some situations exhibited differential response towards anti-cytoskeletal drugs, especially the microtubule disruptor Oryzalin. Our observations indicate that FH1 participates in the control of microtubule dynamics, possibly via its effects on actin, subsequently influencing cell morphogenesis and macroscopic organ development.

    ABSTRACT: Various kinds of organisms, including microalgae, accumulate neutral lipids in distinct intracellular compartments called lipid droplets. Generally, lipid droplets are generated from the endoplasmic reticulum and particular proteins localize on their surface. Some of these proteins function as structural proteins to prevent fusion between the lipid droplets, and the others could have an enzymatic role or might be involved in intracellular membrane trafficking. However, information about lipid droplet proteins in microalgae is scarce as compared with that in animals and land plants. We focused on the oil-producing, marine, pennate diatom Phaeodactylum tricornutum that forms lipid droplets during nitrogen deprivation and we investigated the proteins located on the lipid droplets. After 6 days of cultivation in a nitrate-deficient medium, the mature lipid droplets were isolated by sucrose density gradient centrifugation. Proteomic analyses revealed five proteins, with Stramenopile-type lipid droplet protein (StLDP) being the most abundant protein in the lipid droplet fraction. Though the primary sequence of StLDP did not have homology to any known lipid droplet proteins, StLDP had a central hydrophobic domain. This structural feature is also detected in oleosin of the land plant and lipid droplet surface protein (LDSP) of the Nannochloropsis. As a proline knot motif of oleosin, conservative proline residues existed in the hydrophobic domain. StLDP was upregulated during nitrate deprivation and fluctuations of StLDP expression levels corresponded with the size of the lipid droplets.

    ABSTRACT: Reactive oxygen species (ROS) have dual functions in plant cells as cytotoxic molecules and emergency signals. The balance between the production and scavenging of these molecules in chloroplasts, major sites for the production of ROS, is one of the key determinants for plant acclimation to stress conditions. The water-water cycle is a crucial regulator of ROS levels in chloroplasts. In this cycle, the stromal and thylakoid membrane-attached isoforms of ascorbate peroxidase (sAPX and tAPX, respectively) are involved in the metabolism of H2O2. Current genome and phylogenetic analyses suggest that the first mono-functional APX was generated as sAPX in unicellular green algae, and that tAPX occurred in multicellular charophytes during plant evolution. Chloroplastic APXs, especially tAPX, have been considered to be the source of a bottleneck in the water-water cycle, at least in higher plants, because of their high susceptibility to H2O2. A number of studies have succeeded in improving plant stress resistance by reinforcing the fragile characteristics of the enzymes. However, researchers have unexpectedly failed to find a 'stress-sensitive phenotype' among loss-of-function mutants at least in the laboratory conditions. Interestingly, the susceptibility of enzymes to H2O2 may have been acquired during plant evolution, thereby allowing for the flexible use of H2O2 as a signaling molecule in plants, and this is supported by growing lines of evidence for the physiological significance of chloroplastic H2O2 as a retrograde signal in plant stress responses. By overviewing historical, biochemical, physiological, and genetic studies, we herein discuss the diverse functions of chloroplastic APXs as antioxidant enzymes and signaling modulators.

    ABSTRACT: TOMATOMA (http://tomatoma.nbrp.jp/) is a tomato mutant database providing visible phenotypic data of tomato mutant lines generated by ethylmethane sulfonate (EMS) treatment or γ-ray irradiation in the genetic background of Micro-Tom, a small and rapidly growing variety. To increase mutation efficiency further, mutagenized M3 seeds were subjected to a second round of EMS treatment; M3M1 populations were generated. These plants were self-pollinated, and 4,952 lines of M3M2 mutagenized seeds were generated. We checked for visible phenotypes in the M3M2 plants, and 618 mutant lines with 1,194 phenotypic categories were identified. In addition to the phenotypic information, we investigated Brix values and carotenoid contents in the fruits of individual mutants. Of 466 samples from 171 mutant lines, Brix values and carotenoid contents were between 3.2% and 11.6% and 6.9 and 37.3 µg g–1 FW, respectively. This metabolite information concerning the mutant fruits would be useful in breeding programs as well as for the elucidation of metabolic regulation. Researchers are able to browse and search this phenotypic and metabolite information and order seeds of individual mutants via TOMATOMA. Our new Micro-Tom double-mutagenized populations and the metabolic information could provide a valuable genetic toolkit to accelerate tomato research and potential breeding programs.

    ABSTRACT: The miR156-modulated SQUAMOSA PROMOTER BINDING PROTEIN-LIKE (SPL) is involved in diverse biological processes that include growth, development and metabolism. Here, we report that the Arabidopsis miR156 and SPL3 as regulators play important roles in phosphate (Pi) deficiency response. MiR156 was induced during Pi starvation whereas SPL3 expression was repressed. Phenotypes of reduced rhizosphere acidification and decreased anthocyanin accumulation were observed in 35S:MIM156 (via target mimicry) transgenic plants under Pi deficiency. The content and uptake of Pi in 35S:MIM156 Arabidopsis plants were increased compared with wild-type (Col-0 ecotype) plants. 35S:rSPL3 seedlings showed similar anthocyanin accumulation and Pi content phenotypes to those of 35S:MIM156 plants. Chromatin immunoprecipitation and an electrophoretic mobility shift assay indicated that the SPL3 protein directly bound to GTAC motifs in the PLDZ2, Pht1;5 and miR399f promoters. The expression of several Pi starvation-induced genes was increased in 35S:MIM156 and 35S:rSPL3 plants, including high-affinity Pi transporters, Mt4/TPS1-like genes and phosphatases. Collectively, our results suggest that the miR156–SPL3–Pht1;5 (–PLDZ2 and miR399f) pathways constitute a component of the Pi deficiency-induced regulatory mechanism of Arabidopsis.

    ABSTRACT: In the era of energy and food shortage, microalgae have been gained much attention as promising sources of biofuels and food ingredients. However, only a small fraction of microalgal genes have been functionally characterized. Here, we have developed the Algae Gene Coexpression Database (ALCOdb, http://alcodb.jp), which provides gene coexpression information to survey gene modules for a function of interest. ALCOdb currently supports two model algae: the green alga Chlamydomonas reinhardtii and the red alga Cyanidioschyzon merolae. Users can retrieve coexpression information for genes of interest through three unique data pages: (i) Coexpressed Gene List, (ii) Gene Information and (iii) Coexpressed Gene Network. In addition to the basal coexpression information, ALCOdb also provides several advanced functionalities such as an expression profile viewer and a differentially expressed gene search tool. Using these user interfaces, we demonstrated that our gene coexpression data have the potential to detect functionally related genes and are useful in extrapolating the biological roles of uncharacterized genes. ALCOdb will facilitate the molecular and biochemical studies of microalgal biological phenomena, such as lipid metabolism and organelle development, and promote the evolutionary understanding of plant cellular systems.

    ABSTRACT: The genus Vigna includes legume crops such as cowpea, mungbean and azuki bean, as well as >100 wild species. A number of the wild species are highly tolerant to severe environmental conditions including high-salinity, acid or alkaline soil; drought; flooding; and pests and diseases. These features of the genus Vigna make it a good target for investigation of genetic diversity in adaptation to stressful environments; however, a lack of genomic information has hindered such research in this genus. Here, we present a genome database of the genus Vigna, Vigna Genome Server (‘VigGS’, http://viggs.dna.affrc.go.jp), based on the recently sequenced azuki bean genome, which incorporates annotated exon–intron structures, along with evidence for transcripts and proteins, visualized in GBrowse. VigGS also facilitates user construction of multiple alignments between azuki bean genes and those of six related dicot species. In addition, the database displays sequence polymorphisms between azuki bean and its wild relatives and enables users to design primer sequences targeting any variant site. VigGS offers a simple keyword search in addition to sequence similarity searches using BLAST and BLAT. To incorporate up to date genomic information, VigGS automatically receives newly deposited mRNA sequences of pre-set species from the public database once a week. Users can refer to not only gene structures mapped on the azuki bean genome on GBrowse but also relevant literature of the genes. VigGS will contribute to genomic research into plant biotic and abiotic stresses and to the future development of new stress-tolerant crops.

    ABSTRACT: Target of rapamycin (TOR) kinase is known to be a controller of cell growth and aging, which determines the fine balance between growth rates and energy availabilities. It has been reported that many eukaryotes express TOR genes. In plants, TOR signaling modifies growth and development in response to a plant’s energy status. An example of TOR action can be found in the root apices, which are active organs that explore the soil environment via vigorous growth and numerous tropisms. The exploratory nature of root apices requires a large energy supply for signaling, as well as for cell division and elongation. In the case of negative tropisms, roots must respond quickly to avoid patches of unfavorable soil conditions, again by consuming precious energy reserves. Here we review the current findings on TOR signaling in plants and animals, and propose possible roles for this important complex in driving plant root negative tropisms, particularly during light escape and salt avoidance behavior.

    ABSTRACT: The cyanobacterial circadian-related protein, Pex, accumulates in the dark period of the diurnal light–dark cycle. After the diurnal cycle, an approximately 3 h advance in the phase of the circadian bioluminescence rhythm is observed in pex-deficient mutants, as compared with the wild type. However, it is unclear what type of photosensing mechanism regulates the accumulation and the phase change. In monochromatic light irradiation experiments, Pex accumulation was strongly repressed under blue light conditions; however, only small reductions in Pex accumulation were observed under red or green light conditions. After the diurnal cycle of 12 h of white fluorescent light and 12 h of blue light, the phase advance was repressed more than that of the cycle of 12 h red (or green) light. The phase advance also occurred after 16 h light/8 h dark cycles (long-day cycles) but did not occur after 8 h light/16 h dark cycles (short-day cycles). While Pex is a unique winged helix transcription factor harboring secondary structures (α0 and α4 helices), the importance of the structures is not understood. In in vivo experiments with site-directed mutations in the α0 helix, the obtained mutants, in which Pex was missing the hydrophobic side chain at the 28th or 32nd amino acid residue, exhibited no phase delay after the light/dark cycle. In in vitro DNA binding assays, the mutant proteins showed no binding to the promoter region of the clock gene kaiA. From these results, we propose a molecular model which describes the phase delay in cyanobacteria.
