  1. Nagaya S, Yoshida K, Kato K, Akasaka K, Shinmyo A. An insulator element from the sea urchin Hemicentrotus pulcherrimus suppresses variation in transgene expression in cultured tobacco cells. Mol Genet Genomics. 2001;265:405-13 pubmed
    ..These results suggest that the insulator functions to suppress the variation normally associated with transgene expression in tobacco BY2 cells. ..
  2. Nagaya S, Kawamura K, Shinmyo A, Kato K. The HSP terminator of Arabidopsis thaliana increases gene expression in plant cells. Plant Cell Physiol. 2010;51:328-32 pubmed publisher
    ..When combined with the HSP terminator, a translational enhancer increased gene expression levels approximately 60- to 100-fold in transgenic plants. ..
  3. Yoda H, Ogawa M, Yamaguchi Y, Koizumi N, Kusano T, Sano H. Identification of early-responsive genes associated with the hypersensitive response to tobacco mosaic virus and characterization of a WRKY-type transcription factor in tobacco plants. Mol Genet Genomics. 2002;267:154-61 pubmed
    ..These results indicate the presence of salicylic acid-independent pathways for HR signal transduction, in which a novel type of WRKY protein(s) may play a critical role for the activation of defense. ..
  4. Shoji T, Winz R, Iwase T, Nakajima K, Yamada Y, Hashimoto T. Expression patterns of two tobacco isoflavone reductase-like genes and their possible roles in secondary metabolism in tobacco. Plant Mol Biol. 2002;50:427-40 pubmed
    ..The A622 expression patterns were qualitatively similar to those of putrescine N-methyltransferase, the first enzyme in nicotine biosynthesis, suggesting that A622 may function in the metabolism of nicotine or related alkaloids. ..
  5. Yang S, Berberich T, Miyazaki A, Sano H, Kusano T. Ntdin, a tobacco senescence-associated gene, is involved in molybdenum cofactor biosynthesis. Plant Cell Physiol. 2003;44:1037-44 pubmed
    ..Abscisic acid and indole-3-acidic acid, whose biosynthetic pathways require Moco, up-regulated Ntdin expression. Taken together, it is concluded that Ntdin functions in a certain step in Moco biosynthesis. ..
  6. Sawada K, Hasegawa M, Tokuda L, Kameyama J, Kodama O, Kohchi T, et al. Enhanced resistance to blast fungus and bacterial blight in transgenic rice constitutively expressing OsSBP, a rice homologue of mammalian selenium-binding proteins. Biosci Biotechnol Biochem. 2004;68:873-80 pubmed publisher
    ..Additionally, the OsSBP protein might have a role in modulating the defense mechanism to biotic stress in rice...
  7. Thao N, Chen L, Nakashima A, Hara S, Umemura K, Takahashi A, et al. RAR1 and HSP90 form a complex with Rac/Rop GTPase and function in innate-immune responses in rice. Plant Cell. 2007;19:4035-45 pubmed
    ..Together, our results indicate that Rac1, RAR1, HSP90, and HSP70 form one or more protein complexes in rice cells and suggest that these proteins play important roles in innate immunity in rice. ..
  8. Nakagawa M, Shimamoto K, Kyozuka J. Overexpression of RCN1 and RCN2, rice TERMINAL FLOWER 1/CENTRORADIALIS homologs, confers delay of phase transition and altered panicle morphology in rice. Plant J. 2002;29:743-50 pubmed
  9. Nakajima K, Furutani I, Tachimoto H, Matsubara H, Hashimoto T. SPIRAL1 encodes a plant-specific microtubule-localized protein required for directional control of rapidly expanding Arabidopsis cells. Plant Cell. 2004;16:1178-90 pubmed
    ..These observations suggest that SPR1 is a plant-specific MT-localized protein required for the maintenance of growth anisotropy in rapidly elongating cells. ..
