    Summary:The pepper L gene conditions the plant's resistance to Tobamovirus spp. Alleles L(1), L(2), L(3), and L(4) confer a broadening spectra of resistance to different virus pathotypes. In this study, we report the genetic basis for the hierarchical interaction between L genes and Tobamovirus pathotypes. We cloned L(3) using map-based methods, and L(1), L(1a), L(1c), L(2), L(2b), and L(4) using a homology-based method. L gene alleles encode coiled-coil, nucleotide-binding, leucine-rich repeat (LRR)-type resistance proteins with the ability to induce resistance response to the viral coat protein (CP) avirulence effectors by themselves. Their different recognition spectra in original pepper species were reproduced in an Agrobacterium tuntefaciens-mediated transient expression system in Nicotiana benthamiana. Chimera analysis with L(1), which showed the narrowest recognition spectrum, indicates that the broader recognition spectra conferred by L(2), Lab, L(3), and L(4) require different subregions of the LRR domain. We identified a critical amino acid residue for the determination of recognition spectra but other regions also influenced the L genes' resistance spectra. The results suggest that the hierarchical interactions between L genes and Tobamovirus spp. are determined by the interaction of multiple subregions of the LRR domain of L proteins with different viral CP themselves or some protein complexes including them.
  • A protein containing an XYPPX repeat and a C2 domain is associated with virally induced hypersensitive cell death in plants, Masaru Sakamoto, Reiko Tomita, Kappei Kobayashi, FEBS LETTERS, FEBS LETTERS, 583(15), 2552 - 2556, Aug. 2009 , Refereed
    Summary:In this study, we characterized a Capsicum hypersensitive response (HR)-associated gene, SS52, which encodes a protein that contains an N-terminal C2 domain and a C-terminal XYPPX repeat. Expression analyses revealed that SS52 and its homologue in Arabidopsis were induced by infection with incompatible viruses, indicating the conserved function of this gene. SS52 was not induced by treatment with defense-related hormones, but was induced by abiotic stresses, including wounding. Overexpression of SS52 in tobacco plants suppressed the spread of HR cell death and restricted the spread of an incompatible virus from local lesions. Collectively, the results suggest that SS52 negatively regulates plant HR cell death. (c) 2009 Federation of European Biochemical Societies. Published by Elsevier B.V. All rights reserved.
  • Recombinant plant dsRNA-binding protein as an effective tool for the isolation of viral replicative form dsRNA and universal detection of RNA viruses, Kappei Kobayashi, Reiko Tomita, Masaru Sakamoto, JOURNAL OF GENERAL PLANT PATHOLOGY, JOURNAL OF GENERAL PLANT PATHOLOGY, 75(2), 87 - 91, Apr. 2009 , Refereed
    Summary:The isolation of viral replicative form (RF) double-stranded RNA (dsRNA) is a classic technique for plant virus detection when the virus species cannot be predicted from disease symptoms. However, the method has not been very widely used, most likely because dsRNA isolation using CF-11 cellulose is laborious and time-consuming. Here we report an alternative tool, a recombinant plant dsRNA-binding protein, to isolate dsRNA. This tool enables us to isolate viral RF dsRNA in an hour from either extracted nucleic acids or crude detergent extracts. Combining this technique with sequence-non-specific reverse transcription, PCR amplification, cloning, and sequencing, a variety of viruses were efficiently detected using a single set of reagents and procedures.
  • Fine mapping and DNA fiber FISH analysis locates the tobamovirus resistance gene L(3) of Capsicum chinense in a 400-kb region of R-like genes cluster embedded in highly repetitive sequences, R. Tomita, J. Murai, Y. Miura, H. Ishihara, S. Liu, Y. Kubotera, A. Honda, R. Hatta, T. Kuroda, H. Hamada, M. Sakamoto, I. Munemura, O. Nunomura, K. Ishikawa, Y. Genda, S. Kawasaki, K. Suzuki, K. Meksem, K. Kobayashi, THEORETICAL AND APPLIED GENETICS, THEORETICAL AND APPLIED GENETICS, 117(7), 1107 - 1118, Nov. 2008 , Refereed
    Summary:The tobamovirus resistance gene L(3) of Capsicum chinense was mapped using an intra-specific F2 population (2,016 individuals) of Capsicum annuum cultivars, into one of which had been introduced the C. chinense L(3) gene, and an inter-specific F2 population (3,391 individuals) between C. chinense and Capsicum frutescence. Analysis of a BAC library with an AFLP marker closely linked to L(3)-resistance revealed the presence of homologs of the tomato disease resistance gene I2. Partial or full-length coding sequences were cloned by degenerate PCR from 35 different pepper I2 homologs and 17 genetic markers were generated in the inter-specific combination. The L(3) gene was mapped between I2 homolog marker IH1-04 and BAC-end marker 189D23M, and located within a region encompassing two different BAC contigs consisting of four and one clones, respectively. DNA fiber FISH analysis revealed that these two contigs are separated from each other by about 30 kb. DNA fiber FISH results and Southern blotting of the BAC clones suggested that the L(3) locus-containing region is rich in highly repetitive sequences. Southern blot analysis indicated that the two BAC contigs contain more than ten copies of the I2 homologs. In contrast to the inter-specific F2 population, no recombinant progeny were identified to have a crossover point within two BAC contigs consisting of seven and two clones in the intra-specific F2 population. Moreover, distribution of the crossover points differed between the two populations, suggesting linkage disequilibrium in the region containing the L locus.
  • A primer-introduced restriction analysis-PCR-based method to analyse Pepper mild mottle virus populations in plants and field soil with respect to virus mutations that break L(3) gene-mediated resistance of Capsicum plants, M. Sakamoto, R. Tomita, H. Hamada, Y. Iwadate, I. Munemura, K. Kobayashi, PLANT PATHOLOGY, PLANT PATHOLOGY, 57(5), 825 - 833, Oct. 2008 , Refereed
    Summary:One or a few nucleotide changes in the coat protein gene reportedly confer Pepper mild mottle virus (PMMoV) with the ability to overcome L(3) gene-mediated resistance in Capsicum plants. Primer-introduced restriction analysis-PCR (PIRA-PCR) was set up to detect four known resistance-breaking mutations. Each mutation from the L(3)-breaking PMMoV strains was successfully detected by reverse transcription-PCR amplification of the viral coat protein gene, PCR amplification of the regions containing the mutations with restriction site-introducing primers, followed by restriction analysis. Since PIRA-PCR primers were designed such that only PCR products from L(3)-breaking PMMoV strains can be digested by appropriate restriction enzymes, L(3)-breaking strains could be detected when they comprised no more than 20% of the mixture with non-L(3)-breaking strain. Using this PIRA-PCR-based method, L(3)-breaking PMMoV was detected in field soil samples taken from the base of both diseased and non-diseased plants harbouring L(3). The results show that PIRA-PCR is useful to quickly detect L(3)-breaking PMMoV strains not only in Capsicum plants harbouring the L(3) resistance gene but also in field soil, which serves as a reservoir of infectious viruses.
  • Involvement of hydrogen peroxide in leaf abscission signaling, revealed by analysis with an in vitro abscission system in Capsicum plants, Masaru Sakamoto, Ikuko Munemura, Reiko Tomita, Kappei Kobayashi, PLANT JOURNAL, PLANT JOURNAL, 56(1), 13 - 27, Oct. 2008 , Refereed
    Summary:Although auxin and ethylene play pivotal roles in leaf abscission, the subsequent signaling molecules are poorly understood. This is mainly because it is difficult to effectively treat the intact abscission zone (AZ) with pharmacological reagents. We developed an in vitro experimental system that reproduces stress-induced leaf abscission in planta. In this system, 1-mm-thick petiole strips, encompassing the AZ, were separated within 4 days of abscission at the AZ through cell wall degradation in an auxin depletion- and ethylene-dependent manner. The system allowed us to show that hydrogen peroxide (H(2)O(2)) is involved in abscission signaling. Microscopic analyses revealed continuous H(2)O(2) production by AZ cells. H(2)O(2) scavengers and diphenylene iodonium, an inhibitor of NADPH oxidase, suppressed in vitro abscission and cellulase expression. Conversely, the application of H(2)O(2) promoted in vitro abscission and expression of cellulase. Ethephon-induced abscission was suppressed by inhibitors of H(2)O(2) production, whereas the expression of ethylene-responsive genes was unaffected by both H(2)O(2) and an H(2)O(2) inhibitor. These results indicated that H(2)O(2) acts downstream from ethylene in in vitro abscission signaling. In planta, salinity stress induced the expression of genes that respond to ethylene and reactive oxygen species, and also induced H(2)O(2) production at the AZ, which preceded leaf abscission. These results indicate that H(2)O(2) has roles in leaf abscission associated with ethylene both in vitro and in planta.

    Summary:Reactive oxygen species (ROS) are produced in response to many environmental stresses, such as UV, chilling, salt and pathogen attack. These stresses also accompany leaf abscission in some plants, however, the relationship between these stresses and abscission is poorly understood. In our recent report, we developed an in vitro abscission system that reproduces stress-induced pepper leaf abscission in planta. Using this system, we demonstrated that continuous production of hydrogen peroxide (H 2O2) is involved in leaf abscission signaling. Continuous H2O2 production is required to induce expression of the cell wall-degrading enzyme, cellulase and functions downstream of ethylene in abscission signaling. Furthermore, enhanced production of H2O 2 occurs at the execution phase of abscission, suggesting that H 2O2 also plays a role in the cell-wall degradation process. These data suggest that H2O2 has several roles in leaf abscission signaling. Here, we propose a model for these roles. ©2008 Landes Bioscience.
  • Two phases of intracellular reactive oxygen species production during victorin-induced cell death in oats, Masaru Sakamoto, Yasuomi Tada, Hitoshi Nakayashiki, Yukio Tosa, Shigeyuki Mayama, Journal of General Plant Pathology, Journal of General Plant Pathology, 71(6), 387 - 394, Dec. 2005 , Refereed
    Summary:Reactive oxygen species (ROS) are thought to be involved in various forms of programmed cell death (PCD) in animal and plant cells. PCD, along with the production of ROS, occurs during plant-pathogen interactions. Here we show that victorin, a host-specific toxin produced by Cochliobolus victoriae, which causes victoria blight of oats, induces two phases of intracellular ROS production in victorin-sensitive oat mesophyll cells. The initial production of ROS is restricted at mitochondria and not accompanied with cellular oxidative damage. Later production of ROS is dispersed into cells concomitant with lipid peroxidation, chloroplast dysfunction, and cell death. Superoxide dismutase can clearly suppress the initial ROS production and delay the progression of cell death. These data indicate that the initial ROS production may be involved in the cell death induction process, and the later ROS production may play important roles in events leading to cellular disruption. © The Phytopathological Society of Japan and Springer-Verlag 2005.
  • Victorin triggers programmed cell death and the defense response via interaction with a cell surface mediator, Y Tada, Y Ohura, S Betsuyaku, T Shinogi, M Sakamoto, Y Ohura, S Hata, T Mori, Y Tosa, S Mayama, PLANT AND CELL PHYSIOLOGY, PLANT AND CELL PHYSIOLOGY, 46(11), 1787 - 1798, Nov. 2005 , Refereed
    Summary:The host-selective toxin victorin is produced by Cochliobolus victoriae, the causal agent of victoria blight of oats. Victorin has been shown to bind to the P protein of the glycine decarboxylase complex (GDC) in mitochondria, and induce defense-related responses such as phytoalexin synthesis, extracellular alkalization and programmed cell death. However, evidence demonstrating that the GDC plays a critical role in the onset of cell death is still lacking, and the role of defense-like responses in the pathogenicity has yet to be elucidated. Here, cytofluorimetric analyses, using the fluorescein (VicFluor) or bovine serum albumin-fluorescein derivative of victorin (VicBSA), demonstrated that victorin-induced cell death occurs before these conjugates traverse the plasma membrane. As with native victorin, VicBSA clearly elicits apoptosis-like cell death, production of phytoalexin, extracellular alkalization, and generation of nitric oxide and reactive oxygen intermediates. These results suggest that the initial recognition of victorin takes place on the cell surface, not in mitochondria, and leads to the activation of a battery of victorin-induced responses. Pharmacological studies showed that extracellular alkalization is the essential regulator for both victorin- and VicBSA-induced cellular responses. We propose a model where victorin may kill the host cell by activating an HR-like response, independent of the binding to the GDC, through ion fluxes across the plasma membrane.
  • Coordinate involvement of cysteine protease and nuclease in the executive phase of plant apoptosis, K Kusaka, Y Tada, T Shigemi, M Sakamoto, H Nakayashiki, Y Tosa, S Mayama, FEBS LETTERS, FEBS LETTERS, 578(3), 363 - 367, Dec. 2004 , Refereed
    Summary:We have developed an oat cell-free apoptosis system to investigate the execution mechanisms of plant apoptosis. Cell extracts derived from oat tissues undergoing toxin (victorin)-induced apoptosis caused nuclear collapse and internucleosomal DNA fragmentation in isolated nuclei. Pharmacological studies revealed that cysteine protease, which is E-64-sensitive but insensitive to caspase-specific inhibitors, is a crucial component in the morphological change of isolated nuclei, and that nuclease and the cysteine protease act cooperatively to induce the apoptotic DNA laddering. Interestingly, this finding is contrasted with those in well-studied animal cell-free systems in which an apoptotic endonuclease is solely responsible for the DNA fragmentation.

  • Nitric oxide and reactive oxygen species do not elicit hypersensitive cell death but induce apoptosis in the adjacent cells during the defense response of oat, Y Tada, T Mori, T Shinogi, N Yao, S Takahashi, S Betsuyaku, M Sakamoto, P Park, H Nakayashiki, Y Tosa, S Mayama, MOLECULAR PLANT-MICROBE INTERACTIONS, MOLECULAR PLANT-MICROBE INTERACTIONS, 17(3), 245 - 253, Mar. 2004 , Refereed
    Summary:Nitric oxide (NO) acts as a signaling molecule in many cellular responses in plants and animals. Oat plants (Avena sativa L.) evoke the hypersensitive response (HR), which shares morphological and biochemical features with mammalian apoptosis, such as DNA laddering and heterochromatin condensation, in response to the avirulent crown rust fungus (Puccinia coronata f. sp. avenae). We examined the role of NO and reactive oxygen species (ROS) in the initiation of hypersensitive cell death, which is induced by direct contact with the pathogen, and apoptotic cell death in the adjacent cells. Cytofluorimetric analysis using the fluorescent NO probe DAF and the H2O2 probe DCF demonstrated that NO and H2O2 were generated simultaneously in primary leaves at an early stage of the defense response. The NO scavenger 2-(4-carboxyphenyl)-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide (cPTIO) markedly enhanced H2O2 accumulation detected by 3,3-diaminobenzidine staining and DCF, whereas treatment with the NO donor S-nitroso-N-acetylpenicillantine (SNAP) strongly suppressed it. Superoxide dismutase (SOD) increased NO accumulation, suggesting that endogenous NO may modulate the level of H2O2 by interacting with O-2(-) in the HR lesion. Cytological observation showed that administration of cPTIO, SNAP, or SOD had no effect on elicitation of hypersensitive cell death, but clearly reduced heterochromatin condensation in the nearby cells and DNA laddering. These findings indicate that NO and ROS are not essential mediators for the initiation of hypersensitive cell death. However, NO and O-2(-) but not H2O2 are required for the onset of apoptotic cell death in the adjacent cells, where excess NO may exert its anti-apoptotic function by regulating cellular redox state.

  • Developments of mass production method of sweetpotatoes and methane fermentation, SUZUKI Takahiro, SAKAMOTO Masaru, Proceedings of the Annual Conference of The Japan Institute of Energy,   2017 08
    Summary:

    Mass production of sweetpotatoes by a cheap cultivation method was achieved with small pots by optimizing the elongation space of the roots and the hygroscopic condition of the soil. In Okinawa we planted vine of sweetpotato in October, and harvested in April. The amount of sweetpotatoes cultivated in the winter months was reached to 7.3 kg/m2, which was three times the national average to grow in the summer. The result showed that annual production of 20kg/m2 sweetpotatoes is feasible by further optimizing the growth condition. For the purpose to use sweetpotatoes as fuel, technological issues of the methane fermentation and the gas power generation system were investigated.

  • Effect of root zone irrigation system on mass production of sweetpotatoes, SUZUKI Takahiro, SAKAMOTO Masaru, Proceedings of the Annual Conference of The Japan Institute of Energy,   2016 08
    Summary:

    The innovation is required to production of a large amount of biomass by cultivation of domestic photosynthetic plant and to replace fossil fuels. The author has found that the best crop is sweetpotato cultivated in multilayer system. So far, the 4-layers cultivation method using a triangular shelf showed that it is possible to sweetpotato production of about 20kg/m2. This is eight times the amount of domestic average yield (2.5kg/m2). However, the soil hygroscopic level decreased quickly and the production of the sweetpotatoes suppressed significantly, were found by the multi-layer cultivation system. Therefore we investigated the influence of the basic irrigation state to produce sweetpotatoes. As the result the yield of sweetpotatoes cultivated with root zone irrigation system increased to 179% of the amount of the past. In addition, the root zone irrigation system was effective to increase the weight of the mass production of sweetpotatoes by increasing the density of the vine seeding per area.
