Refereed, Plant and Cell Physiology, Oxford University Press, Functionally Diversified Members of the MIR165/6 Gene Family Regulate Ovule Morphogenesis in Arabidopsis thaliana, Kayo Hashimoto; Shunsuke Miyashima; Kumi Sato-Nara; Toshihiro Yamada; Keiji Nakajima, The ovules of flowering plants consist of a central embryo sac and surrounding layers of the inner and outer integument. As these structural units eventually give rise to the embryo/endosperm and seed coat, respectively, a precisely organized ovule structure is essential for successful fertilization and seed production. In Arabidopsis thaliana, correct ovule patterning depends on the restricted expression of the CLASS III HOMEODOMAIN LEUCINE ZIPPER (HD-ZIP III) gene PHABULOSA (PHB) in the apical region of the incipient inner integument, which in turn is regulated via post-transcriptional suppression by miR165 and miR166 (miR165/6) derived from multiple MIR165/6 genes. While a common subset of MIR165/6 genes regulate PHB expression in the root meristem, leaf primordium and embryo, it is unknown whether the same MIR165/6 subset also regulate PHB expression during ovule development. Furthermore, it is unclear where in the ovule primordia miR165/6 are produced. Here, we show that a distinct set of MIR165/6 genes that are highly expressed in the small regions of early ovule primordia restrict the PHB expression domain to promote integument formation. MIR165/6 genes that function in ovule development are phylogenetically distinct from those acting in roots and leaf primordia. Taken together, our data suggest that members of the MIR165/6 gene family are diversified in their expression capacity to establish elaborate PHB expression patterns depending on the developmental context, thereby allowing HD-ZIP III transcription factors to regulate multiple aspects of plant development., 01 May 2018, 59, 5, 1017, 1026, Scientific journal, 10.1093/pcp/pcy042
Refereed, Plants, MDPI AG, Accumulation of TIP2;2 aquaporin during dark adaptation is partially phyA dependent in roots of Arabidopsis seedlings, Yumi Uenishi; Yukari Nakabayashi; Ayako Tsuchihira; Mari Takusagawa; Kayo Hashimoto; Masayoshi Maeshima; Kumi Sato-Nara, Light regulates the expression and function of aquaporins, which are involved in water and solute transport. In Arabidopsis thaliana, mRNA levels of one of the aquaporin genes, TIP2
2, increase during dark adaptation and decrease under far-red light illumination, but the effects of light at the protein level and on the mechanism of light regulation remain unknown. Numerous studies have described the light regulation of aquaporin genes, but none have identified the regulatory mechanisms behind this regulation via specific photoreceptor signaling. In this paper, we focus on the role of phytochrome A (phyA) signaling in the regulation of the TIP2
2 protein. We generated Arabidopsis transgenic plants expressing a TIP2
2-GFP fusion protein driven by its own promoter, and showed several differences in TIP2
2 behavior between wild type and the phyA mutant. Fluorescence of TIP2
2-GFP protein in the endodermis of roots in the wild-type seedlings increased during dark adaptation, but not in the phyA mutant. The amount of the TIP2
2-GFP protein in wild-type seedlings decreased rapidly under far-red light illumination, and a delay in reduction of TIP2
2-GFP was observed in the phyA mutant. Our results imply that phyA, cooperating with other photoreceptors, modulates the level of TIP2
2 in Arabidopsis roots., 01 Mar. 2014, 3, 1, 177, 195, Scientific journal, 10.3390/plants3010177
Refereed, Plant Signaling and Behavior, Diurnal changes in shoot water dynamics are synchronized with hypocotyl elongation in Arabidopsis thaliana, Haruki Ishikawa; Kumi Sato-Nara; Tomoyuki Takase; Hitoshi Suzuki, We recently demonstrated the circadian clock modulated water dynamics in the roots of a small model plant, Arabidopsis thaliana, by the Nuclear Magnetic Resonance (NMR) microimaging technique. Our developed technique was able to visualize the water distribution that depended on differences in the 1H signal among region in the shoot, such as the shoot apex, the hypocotyl and the root shoot junction. Water content in the shoot increased during periods of light in comparison with dark periods, and continued through the early stage of seedling growth until the dark period. When the water content changed, elongation and/or movement occurred in the hypocotyl, and these events were synchronized. The water dynamics of the shoot also displayed an opposite phase with the root water dynamics. © 2013 Landes Bioscience., Mar. 2013, 8, 3, e23250.2, Scientific journal, 10.4161/psb.23250
Refereed, PLANT AND CELL PHYSIOLOGY, OXFORD UNIV PRESS, A Comprehensive Expression Analysis of the Arabidopsis MICRORNA165/6 Gene Family during Embryogenesis Reveals a Conserved Role in Meristem Specification and a Non-Cell-Autonomous Function, Shunsuke Miyashima; Minami Honda; Kayo Hashimoto; Kiyoshi Tatematsu; Takashi Hashimoto; Kumi Sato-Nara; Kiyotaka Okada; Keiji Nakajima, One of the most fundamental events in plant ontogeny is the specification of the shoot and root apical meristem (SAM and RAM) in embryogenesis. In Arabidopsis, the restricted expression of class III homeodomain leucine zipper (HD-ZIP III) transcription factors (TFs) at the central-apical domain of early embryos is required for the correct specification of the SAM and RAM. Because the expression of HD-ZIP III TFs is suppressed by microRNA165/166 (miR165/6), elucidation of the sites of miR165/6 production and their activity range is a key to understanding the molecular basis of SAM and RAM specification in embryogenesis. Here, we present a comprehensive reporter analysis of all nine Arabidopsis MICRORNA165/166 (MIR165/6) genes during embryogenesis. We show that five MIR165/6 genes are transcribed in a largely conserved pattern in embryos, with their expression being preferentially focused at the basal-peripheral region of embryos. Our analysis also indicated that MIR165/6 transcription does not depend on SCARECROW (SCR) function in early embryos, in contrast to its requirement in post-embryonic roots. Furthermore, by observing the expression pattern of the miR-resistant PHBmu-GFP (green fluorescent protein) reporter, in either the presence or absence of the MIR165Amu transgene, which targets PHBmu-GFP, we obtained data that indicate a non-cell-autonomous function for miR165 in early embryos. These results suggest that miR165, and possibly miR166 as well, has the capacity to act as a positional cue from the basal-peripheral region of early embryos, and remotely controls SAM and RAM specification with their non-cell-autonomous function., Mar. 2013, 54, 3, 375, 384, Scientific journal, 10.1093/pcp/pcs188
Refereed, PLANT AND CELL PHYSIOLOGY, OXFORD UNIV PRESS, The Circadian Clock Modulates Water Dynamics and Aquaporin Expression in Arabidopsis Roots, Tomoyuki Takase; Haruki Ishikawa; Haruko Murakami; Jun Kikuchi; Kumi Sato-Nara; Hitoshi Suzuki, We have developed a plant growth system to analyze water dynamics in the roots of a small model plant, Arabidopsis thaliana, by nuclear magnetic resonance (NMR) microscopic imaging. Using the two-dimensional slice technique, we obtained a series of images with high signal-to-noise ratio indicating the water distribution in the root. To demonstrate light regulation of water transport in the root and involvement of aquaporin gene expression, we visualized the distribution of water in Arabidopsis roots under various light conditions and compared the data with the expression profiles of two aquaporin genes. (1)H-NMR imaging revealed that water content in Arabidopsis roots is lower in the light than in the dark. This diurnal variation in water content was clearly observed in the basal zone of the root. In addition, an autonomous rhythm of water dynamics was observed under continuous light (LL) and darkness (DD). However, the circadian oscillation in water dynamics was obscured in the early-flowering 3 (elf3) mutant under LL. The expression of both the aquaporin genes, AtPIP1;2 and AtPIP2;1, oscillated with the circadian rhythm under LL conditions in wild-type seedlings, but not in the elf3 mutant. These results demonstrate the advantages of our technique for monitoring water dynamics in roots of living Arabidopsis seedlings, and suggest that the circadian clock modulates water dynamics and aquaporin expression., Feb. 2011, 52, 2, 373, 383, Scientific journal, 10.1093/pcp/pcq198

To evaluate whether gene expression of roots is affected by a dark-FR light cycle, gene expression profiles were analysed for dark-adapted versus light-grown plants and for FR light-illuminated versus dark-adapted plants using the RIKEN Arabidopsis full-length cDNA microarray (containing approximately 7000 independent, full-length cDNA groups). Among candidate dark- and FR-regulated genes, several were further analysed. Eleven dark-inducible and five dark-repressed genes were characterized. Almost all the dark-inducible and -repressed genes were oppositely regulated by FR light illumination. The functions of dark- and FR-responsive genes and the significance of FR light-regulated gene expression in roots under ground are discussed., Nov. 2004, 27, 11, 1387, 1394, Scientific journal
Refereed, PLANTA, SPRINGER-VERLAG, Expression of photosynthesis-related genes and their regulation by light during somatic embryogenesis in Daucus carota, K Sato-Nara; T Demura; H Fukuda, To clarify the spatial and temporal pattern of gene expression for photosynthesis-associated proteins during somatic embryogenesis in Daucus carota L., the localization of mRNAs for three genes, rbcL, Lhcb and por, was examined in dark-grown and light-irradiated somatic embryos by in situ hybridization. The three mRNAs were expressed in common in the mesophyll precursor cells of light-irradiated embryos at the late torpedo and plantlet stages, but characteristic expression patterns of each photosynthesis-related gene were also observed. Expression of rbcL mRNA first occurred throughout the embryo but gradually became localized in the mesophyll precursor cells and cortex during early embryogenesis. Localization of Lhcb mRNA in the mesophyll precursor cells and shoot apical meristem became clear in the early torpedo stage. Expression of Lhcb mRNA was not affected by light during early embryogenesis, but could be induced by light in the torpedo stage, suggesting that light-inducible expression of Lhcb mRNA arises within the torpedo stage. At the late torpedo stage, clear localization of por mRNA started in mesophyll precursor cells of the cotyledon in light-irradiated embryos. Greening potency of the embryo also appeared first at this stage. Therefore, greening and initial differentiation of photosynthetic tissues during somatic embryogenesis seem to be associated with coordinated expression of mRNA for rbcL, Lhcb and por in late torpedo-shaped embryos., May 2004, 219, 1, 23, 31, Scientific journal, 10.1007/s00425-003-1201-6
Refereed, JOURNAL OF PLANT RESEARCH, SPRINGER-VERLAG TOKYO, Sugar-induced adventitious roots in Arabidopsis seedlings, F Takahashi; K Sato-Nara; K Kobayashi; M Suzuki; H Suzuki, The effects of sugars on root growth and on development of adventitious roots were analyzed in Arabidopsis thaliana. Seeds were sown on agar plates containing 0.0-5.0% sugars and placed vertically in darkness (DD) or under long day (LD,16 h : 8 h) conditions, so that the seedlings were constantly attached to the agar medium. In the sucrose-supplemented medium, seedlings showed sustained growth in both DD and LD. However, only dark-grown seedlings developed adventitious roots from the elongated hypocotyl. The adventitious roots began to develop 5 days after imbibition and increased in number until day 11. They could, however, be initiated at any position along the hypocotyl, near the cotyledon or the primary root. They were initiated in the pericycle in the same manner as ordinary lateral roots. Sucrose, glucose and fructose greatly stimulated the induction of adventitious roots, but mannose or sorbitol did not. Sucrose at concentrations of 0.5-2.0% was most effective in inducing adventitious roots, although 5.0% sucrose suppressed induction. Direct contact of the hypocotyl with the sugar-supplemented agar medium was indispensable for the induction of adventitious roots., Apr. 2003, 116, 2, 83, 91, Scientific journal, 10.1007/s10265-002-0074-2

Refereed, PLANTA, SPRINGER-VERLAG, The rates of deceleration of nuclear and organellar DNA syntheses differ in the progenitor cells of the apical meristems during carrot somatic embryogenesis, K Sato-Nara; H Fukuda, The synthesis of DNA in nuclei and organellar nucleoids at the various stages of somatic embryogenesis in carrot (Daucus carota L. cv. Kurodagosun) was analyzed using anti-5-bromo-2'-deoxyuridine (BrdU) immunofluorescence microscopy. The active syntheses of both nuclear and organellar DNA started in the cells forming the embryo groper 3 d after the initiation of embryogenesis, but not in cells forming suspensor-like cell aggregates. In the early globular embryo, active DNA syntheses were continuously observed in the whole embryo groper, except for the progenitor cells of the root apical meristem (RAM) and shoot apical meristem (SAM). These were recognized as slowly cycling cells with a non-BrdU-labelled nucleus and strongly BrdU-labelled organellar nucleoids. At the heart- and torpedo-shaped embryo stages, both nuclear and organellar DNA syntheses were inactive in the presumptive RAM and SAM. Thus, slowing down of organellar DNA synthesis is not coupled with, but is later than, that of nuclear DNA synthesis in the progenitor cells of the embryonic RAM and SAM. These findings clearly indicate that the timing of DNA synthesis is similar in the progenitor cells of both the RAM and SAM in the early stages of somatic embryogenesis., Sep. 2000, 211, 4, 457, 466, Scientific journal
Refereed, PLANT PHYSIOLOGY, AMER SOC PLANT PHYSIOLOGISTS, Stage- and tissue-specific expression of ethylene receptor homolog genes during fruit development in muskmelon, K Sato-Nara; K Yuhashi; K Higashi; K Hosoya; M Kubota; H Ezura, We isolated two muskmelon (Cucumis melo) cDNA homologs of the Arabidopsis ethylene receptor genes ETR1 and ERS1 and designated them Cm-ETR1 (C. melo ETR1; accession no. AF054806) and Cm-ETR1 (C. melo ERS1; accession no. AF037368), respectively. Northern analysis revealed that the level of Cm-ERS1 mRNA in the pericarp increased in parallel with the increase in fruit size and then markedly decreased at the end of enlargement. In fully enlarged fruit the level of Cm-ERS1 mRNA was low in all tissues, whereas that of Cm-ETR1 mRNA was very high in the seeds and placenta. During ripening Cm-ERS1 mRNA increased slightly in the pericarp of fruit before the marked increase of Cm-ETR1 mRNA paralleled climacteric ethylene production. These results indicate that both Cm-ETR1 and Cm-ERS1 play specific roles not only in ripening but also in the early development of melon fruit and that they have distinct roles in particular fruit tissues at particular developmental stages., May 1999, 120, 1, 321, 329, Scientific journal
Not Refereed, Plant Biotechnology, Japanese Society for Plant Cell and Molecular Biology, Ethylene receptors and genetic engineering of ethylene sensitivity in plants, Kumi Sato-Nara; Ken-Ichi Yuhashi; Hiroshi Ezura, Ethylene is a gaseous plant hormone which gives cues to various developmental processes and stress responses in plants. Plants regulate their ethylene sensitivity for programmed development and responses to environmental stresses. After the successful isolation of the Arabidopsis ethylene receptor gene ETR1, ethylene receptor genes have been found in various plant species. Characterization of ethylene receptor genes provides clues to understanding how plants regulate their ethylene sensitivity. This knowledge also gives us potential methods for engineering the ethylene sensitivity of plants. Genetically - engineered plants with reduced ethylene sensitivity will be potential resources for improving crop performance. Moreover, those transgenic plants will provide further information to elucidate the mechanism of how plants regulate their ethylene sensitivity. The recent progress in genetic and protein analyses of ethylene receptors is summarized in this review. The possible strategies for altering the ethylene sensitivity of plants using the ethylene receptor genes are also discussed., 1999, 16, 5, 321, 334, Scientific journal, 10.5511/plantbiotechnology.16.321
Refereed, PLANT AND CELL PHYSIOLOGY, JAPANESE SOC PLANT PHYSIOLOGISTS, Purification and characterization of a mitochondrial DNA polymerase from cultured tobacco cells, K Sato; H Fukuda, The mitochondrial DNA polymerase of tobacco BY-2 cells was purified more than 1,200-fold by column chromatography on DEAE cellulose, phosphocellulose, and Affi-Prep heparin. The enzyme was classified as a gamma-type DNA polymerase, in view of the inhibition of its activity by N-ethylmaleimide and dideoxy TTP, the absence of inhibition by aphidicolin and arabinosyl CTP, the stimulation by KCI, and the ability of the enzyme to utilize poly(A)(dT)(12-18) in the presence of Mn2+ ions. The molecular mass of the native mitochondrial DNA polymerase was estimated to be 70-110 kDa by column chromatography on Superose 12. When DNA polymerase activity was analyzed after sodium dodecyl sulfate-polyacrylamide gel electrophoresis, the activity that polymerized DNA was observed as a single band of a protein with a molecular mass of approximately 110 kDa. Therefore, the tobacco mitochondrial DNA polymerase appears to consist of a single subunit of 110 kDa., Oct. 1996, 37, 7, 989, 995, Scientific journal

By comparing root hair densities of the wild type and the <I>lrh1</I> mutant under continuous light conditions, it was suspected that a mutated gene might induce root hair formation. Mutant seedlings also had shorter roots than wild type, and reduced numbers of lateral roots. A database search revealed that an 11-kilobase sequence adjacent to the location of T-DNA insertion contained two repeated sequences, hundreds of small RNAs, and several proproteins.
