Development of the RIKEN Arabidopsis cDNA Encyclopedia DNA



Dr. Kazuo Shinozaki, project director of the Plant Functional Genomics Research Group, and Dr. Yoshihide Hayashizaki, project director of the Genome Exploration Research Group, have developed the RIKEN Arabidopsis cDNA Encyclopedia DNABookTM in collaboration with Dr. Masatomo Kobayashi of Experimental Plant Division, Department of Biological Systems, RIKEN Bioresource Center. This DNABookTM was made based on the technology originally developed in the Mouse Genome Encyclopedia Project achieved by the Genome Exploration Research Group.
  The DNABookTM contains solidified samples of Arabidopsis full-length cDNAs for transcription factors. This project marks the first time that the full-length cDNA clones of a higher plant have been offered in book form, representing an important new resource that will promote plant science research.
Transcription factors are an important group of genes, acting as a “control tower” that regulates a number of genes. There are more than twice as many transcription factors in plants than in animals, primarily related to the control of various physiological traits. The Plant Functional Genomics Research Group has assessed that there are 1,978 transcription factors in Arabidopsis; the DNABookTM contains spot samples of 1,069 of these factors. Data on these transcription factors has also been released on the RIKEN Arabidopsis Transcription Factor database (http://rarge.gsc.riken.jp/rartf).
