MetabolomicsMetabolomic correlation-network modules in Arabidopsis based on a graph-clustering approach
Deciphering the metabolome is essential for a better understanding of the cellular metabolism as a system. Typical metabolomics data show a few but significant correlations among metabolite levels when data sampling is repeated across individuals grown under strictly controlled conditions. Although ...

MetabolomicsMetabolomic Characterization of Knock-Out Mutants in Arabidopsis - Development of a Metabolite Profiling Database for Knock-Out Mutants in Arabidopsis (MeKO)
Despite recent intensive research efforts in functional genomics, the functions of only a limited number of Arabidopsis (Arabidopsis thaliana) genes have been determined experimentally. Thus, improving gene annotation remains a major challenge in plant science. Because metabolite profiling can chara...

MetabolomicsDefective cytokinin signaling reprograms lipid and flavonoid gene-to-metabolite networks to mitigate high salinity in Arabidopsis

Cytokinin (CK) in plants regulates both developmental processes and adaptation to environmental stress. Arabidopsis histidine phosphotransfer ahp2,3,5 and type-B response regulator arr1,10,12 triple mutants are almost completely defective in CK signaling, and the ahp2,3,5

MetabolomicsFruit setting rewires central metabolism via gibberellin cascades
Fruit set is the process whereby ovaries develop into fruits after pollination and fertilization. The process is induced by the phytohormone gibberellin (GA) in tomatoes, as determined by the constitutive GA response mutant procera However, the role of GA on the metabolic behavior in fruit-setting o...

TranscriptomicsMicroarray analysis of gene expression under different light conditions
The size of tomato fruits are largely dependent on growth conditions. To obtain insights on how light intensity contributes to translocation from a leaf and a fruit, we developed a plant irradiation system based on light-emitting diodes (LEDs) to a leaf. By using this system, we investigated the cha...

MetabolomicsEnhancement of oxidative and drought tolerance in Arabidopsis by overaccumulation of antioxidant flavonoids
The notion that plants use specialized metabolism to protect against environmental stresses needs to be experimentally proven by addressing the question of whether stress tolerance by specialized metabolism is directly due to metabolites such as flavonoids. We report that flavonoids with radical sca...

TranscriptomicsDe novo Assembly and Characterization of Swertia japonica Transcriptome for the Identification of Candidate Genes Involved in the Biosynthesis of Therapeutic Metabolites
Here, we performed deep transcriptome sequencing for the aerial-tissues and the roots of S. japonica, generating over 2 billion raw reads with an average length of 101 nt by using an Illumina paired-end sequencing by HiSeq2000 platform. Using a combined approach of three popular assemblers, de novo ...

TranscriptomicsNew Rice Cold 1 day
Rice plants (Oryza sativa L. cv. Nipponbare) were grown in plastic pots filled with nutrient soil for 2 weeks under flooded lowland conditions with a 12-h light (28C)/12-h dark (25C) regimen (ca. 1500 umol photons mM-^V2 sM-^V1). The plants were cold treated by transfer from 28C to 10C with growth f...
