Journal ArticleDOI
WoLF PSORT: protein localization predictor.
Paul Horton,Keun Joon Park,Takeshi Obayashi,Naoya Fujita,Hajime Harada,C. J. Adams-Collier,Kenta Nakai +6 more
TL;DR: WoLF PSORT converts protein amino acid sequences into numerical localization features; based on sorting signals, amino acid composition and functional motifs such as DNA-binding motifs, which allows a user to understand the evidence (or lack thereof) behind the predictions made for particular proteins.
Journal ArticleDOI
Omics-based identification of Arabidopsis Myb transcription factors regulating aliphatic glucosinolate biosynthesis
Masami Yokota Hirai,Kenjiro Sugiyama,Yuji Sawada,Takayuki Tohge,Takeshi Obayashi,Akane Suzuki,Ryoichi Araki,Nozomu Sakurai,Hideyuki Suzuki,Koh Aoki,Hideki Goda,Osamu Ishizaki Nishizawa,Daisuke Shibata,Kazuki Saito +13 more
TL;DR: Two R2R3-Myb transcription factors are found that positively control the biosynthesis of GSLs in Arabidopsis thaliana by an integrated omics approach and a working model for regulation of GSL production involving these genes, renamed Production of Methionine-Derived Glucosinolate (PMG) 1 and 2 are postulated.
Journal ArticleDOI
Co-expression tools for plant biology: opportunities for hypothesis generation and caveats
Bjoern Usadel,Takeshi Obayashi,Marek Mutwil,Federico M. Giorgi,George W. Bassel,Mimi Tanimoto,Amanda Chow,Dirk Steinhauser,Staffan Persson,Nicholas J. Provart +9 more
TL;DR: Examples from the literature, wherein co-expression has been used to corroborate and discover various aspects of plant biology are presented, and statistical issues including how normalization of gene expression data can influence co- expression results are discussed.
Journal ArticleDOI
12-oxo-phytodienoic acid triggers expression of a distinct set of genes and plays a role in wound-induced gene expression in Arabidopsis.
Nozomi Taki,Yuko Sasaki-Sekimoto,Takeshi Obayashi,Akihiro Kikuta,Koichi Kobayashi,Takayuki Ainai,Kaori Yagi,Nozomu Sakurai,Hideyuki Suzuki,Tatsuru Masuda,Ken-ichiro Takamiya,Daisuke Shibata,Yuichi Kobayashi,Hiroyuki Ohta +13 more
TL;DR: Microarray analysis of Arabidopsis genes revealed that an OPDA signaling pathway functions independently of JA/MeJA signaling and is required for the wounding response inArabidopsis.
Journal ArticleDOI
ATTED-II: a database of co-expressed genes and cis elements for identifying co-regulated gene groups in Arabidopsis
Takeshi Obayashi,Kengo Kinoshita,Kenta Nakai,Masayuki Shibaoka,Shinpei Hayashi,Motoshi Saeki,Daisuke Shibata,Kazuki Saito,Hiroyuki Ohta +8 more
TL;DR: An Arabidopsis thaliana trans-factor and cis-element prediction database that provides co-regulated gene relationships based on co-expressed genes deduced from microarray data and the predicted cis elements to help researchers to clarify the function and regulation of particular genes and gene networks is reported.
