Plants respond and adapt to drought, cold and high-salinity stresses in order to survive. In this study, we applied Arabidopsis Affymetrix tiling arrays to study the whole genome transcriptome under drought, cold, high-salinity and ABA treatment conditions. The bioinformatic analysis using the tiling array data showed that 7,719 non-AGI transcriptional(More)
PosMed (http://omicspace.riken.jp/) prioritizes candidate genes for positional cloning by employing our original database search engine GRASE, which uses an inferential process similar to an artificial neural network comprising documental neurons (or 'documentrons') that represent each document contained in databases such as MEDLINE and OMIM. Given a(More)
Plants respond and adapt to drought, cold, and high-salinity stresses. Stress-inducible gene products function in the stress response and tolerance in plants. Using cDNA microarrays and oligonucleotide microarrays, stress-inducible genes have been identified in various plant species so far. Recently, tiling array technology has become a powerful tool for(More)
The RIKEN integrated database of mammals (http://scinets.org/db/mammal) is the official undertaking to integrate its mammalian databases produced from multiple large-scale programs that have been promoted by the institute. The database integrates not only RIKEN's original databases, such as FANTOM, the ENU mutagenesis program, the RIKEN Cerebellar(More)
In this paper we describe collaborative constraint functional logic programming and the system called Open CFLP that supports this programming paradigm. The system solves equations by collaboration of various equational constraint solvers. The solvers include higher-order lazy narrowing calculi that serve as the interpreter of higher-order functional logic(More)
Building an efficient SPAQRL query over the great variety of copious bio-medical Linked Open Data (LOD) requires users to understand the data schema, and makes it difficult for biologists to handle such data. To address this problem, we challenge to realise a SPARQL query builder that generates a structurally-optimised query by logically analysing the(More)
RNA-directed DNA methylation (RdDM) is a process in which 24 nucleotide (nt) small interfering RNAs (siRNAs) guide de novo cytosine methylation in the homologous genomic DNA region. Of several factors involving 24 nt siRNA accumulation, RNA-dependent RNA polymerase 2 (RDR2) is a key component, because accumulation of 24 nt siRNA disappears in the(More)
UNLABELLED OmicBrowse is a browser to explore multiple datasets coordinated in the multidimensional omic space integrating omics knowledge ranging from genomes to phenomes and connecting evolutional correspondences among multiple species. OmicBrowse integrates multiple data servers into a single omic space through secure peer-to-peer server communications,(More)
Molecular breeding of crops is an efficient way to upgrade plant functions useful to mankind. A key step is forward genetics or positional cloning to identify the genes that confer useful functions. In order to accelerate the whole research process, we have developed an integrated database system powered by an intelligent data-retrieval engine termed(More)
Recent advances in technologies for observing high-resolution genomic activities, such as whole-genome tiling arrays and high-throughput sequencers, provide detailed information for understanding genome functions. However, the functions of 50% of known Arabidopsis thaliana genes remain unknown or are annotated only on the basis of static analyses such as(More)
