Place (http://www.dna.affrc.go.jp/htdocs/PLACE/) is a database of nucleotide sequence motifs found in plant cis-acting regulatory DNA elements. Motifs were extracted from previously published reports on genes vascular plants. In addition to the originally reported, their variations other or species later are also compiled. Documents for each motif PLACE contains, sequence, brief definition and description motif, relevant literature with PubMed ID numbers GenBank accession where available....
The Rice Annotation Project Database (RAP-DB, http://rapdb.dna.affrc.go.jp/) has been providing a comprehensive set of gene annotations for the genome sequence rice, Oryza sativa (japonica group) cv. Nipponbare. Since first release in 2005, RAP-DB updated several times along with assembly updates. Here, we present our newest based on latest assembly, Os-Nipponbare-Reference-IRGSP-1.0 (IRGSP-1.0), which was released 2011. We detected 37,869 loci by mapping transcript and protein sequences 150...
Summary Rice blast, caused by the fungal pathogen Magnaporthe grisea , is one of most serious diseases rice. Here we describe isolation and characterization Pib, rice blast resistance genes. The Pib gene was isolated a map‐based cloning strategy. deduced amino acid sequence product contains nucleotide binding site (NBS) leucine‐rich repeats (LRRs); thus, member NBS‐LRR class plant disease Interestingly, duplication kinase 1a, 2 3a motifs NBS region found in N‐terminal half protein. In...
Summary Fertilizers are often potential environmental pollutants, therefore increasing productivity and the efficiency of nutrient uptake to boost crop yields without risk pollution is a desirable goal. Here, we show that transcription factor encoding gene RDD 1 plays role in improving accumulation various ions rice. was found be targeted by micro RNA miR166. An transgene driven strong constitutive promoter exhibited diurnally oscillating expression similar endogenous , nucleotide...
We characterized a rice monoculm mutant moc2, which showed significantly reduced tiller numbers, pale-green leaves, growth rate, and consequent dwarf phenotype. The feature was attributed to deficiency in the efficient outgrowth of buds, although moc2 produced buds. Inconsistent change observed expression genes involved bud outgrowth, suggesting that has defective function necessary for outgrowth. gene responsible mapped locus encoding cytosolic fructose-1,6-bisphosphatase 1 (FBP1), Tos17...
We report here on the characterization of a putative Dof transcription factor gene in rice (Oryza sativa)--rice daily fluctuations 1 (Rdd1). Daily oscillations Rdd1 expression were retained after transferring to continuous dark (DD) or light (LL) conditions, indicating circadian regulation. However, showed arrhythmic etiolated coleoptiles. Experiments revealed that transcript accumulated up h from DD LL conditions and decreased thereafter. examined using phytochrome (phy)-deficient mutants,...
The temperature dependence of the Debye-Waller factor in dye-doped polymers has been investigated with femtosecond accumulated photon echo. superiority polyvinyl alcohol as host polymer for optical-memory material is ascribed to higher phonon sideband frequency this sample. It pointed out that factor, particular frequency, fundamental importance finding best high-temperature optical memory based on photochemical hole burning.
Although phyAphyBphyC phytochrome-null mutants in rice (Oryza sativa) have morphological changes and exhibit internode elongation, even as seedlings, it is unknown how phytochromes contribute to the control of elongation. A gene for 1-aminocyclopropane-1-carboxylate oxidase (ACO1), which an ethylene biosynthesis contributing was up-regulated seedlings. ACO1 expression controlled mainly by phyA phyB, a histochemical analysis showed that localized basal parts leaf sheaths similar mature...

Although reports on a gene for 1-amino-cyclopropane-1-carboxylate (ACC) oxidase (ACO1) in rice (Oryza sativa L.) suggest that high levels of its transcript are associated with internode elongation deep-water during submergence, the role ACO1 development is largely unknown. The tissue-specificity expression indicated significantly accumulated lower parts elongating internodes at heading stage. Histochemical analysis and situ hybridization showed was localized basal leaf sheaths immediately...
Persistent spectral holes were burned in a film composed of tetrasodium 5,10,15,20-tetra(4-sulfonatophenyl)porphin and polyvinylalcohol at 20 K–80 K. This is the first observation photochemical hole above liquid nitrogen temperature. The width increased with temperature according to power-law dependence from K 80
Abstract 3-Methyl-1,4-pentadiene, 1,4-hexadiene, and 1,3-hexadiene were obtained, in the weight ratio of 2:1:2, by use a ternary catalyst consisting combination ferric chloride triethylaluminum, with triphenylphosphine as third component. The products identified means gas chromatography, infrared spectroscopy, mass NMR, hydrogenation. effects compositions reaction conditions on yield product composition also studied. In order to obtain C6-dienes described above, following are desirable;...
Abstract A new catalyst consisting of a cobaltous chloride-ditertiary phosphine complex and an organoaluminum compound was found to be effective for the selective preparation 1, 4-hexadiene by reaction butadiene with ethylene. The effects variables on activity selectivity in formation were studied. It is considered that coordination ditertiary catalytically activated intermediate essential catalysis. mechanism proposed which involves hydrido-cobalt as intermediate.
Abstract The transcription factor-encoding gene RDD1 increases the uptake of nutrient ions, photosynthetic activity under ambient and high CO 2 conditions, grain productivity, microRNA166 (miR166) regulates its transcript levels. This study found that CRISPR/Cas9 genome editing rice plants to inhibit miR166– pairing ( R1 -Cas plants) increased levels, NH 4 + PO 3− uptake, conditions in rice. However, panicle weight decreased compared with wild-type (WT) plants. Adversely, changes...
The 1-aminocyclopropane-1-carboxylate oxidase gene (ACO1) was upregulated in rice (Oryza sativa L.) phyAphyBphyC mutants lacking any phytochrome and containing the GCC box element, a binding site for ethylene-responsive element protein 1 (OsEREBP1), its promoter region. Since OsEREBP1-like EBL1 (OsEREBP1-LIKE 1) significantly downregulated mutants, suspected to repress ACO1 expression wild-type plants. However, RNA interference plants, total length of these plants slightly shorter than that...
