    ..Finally, high-efficiency secretory production of the HRP C1a was also achieved in transgenic tobacco. ..
  3. Yoshimura K, Miyao K, Gaber A, Takeda T, Kanaboshi H, Miyasaka H, et al. Enhancement of stress tolerance in transgenic tobacco plants overexpressing Chlamydomonas glutathione peroxidase in chloroplasts or cytosol. Plant J. 2004;37:21-33 pubmed

  5. Hibara K, Takada S, Tasaka M. CUC1 gene activates the expression of SAM-related genes to induce adventitious shoot formation. Plant J. 2003;36:687-96 pubmed
    ..Our results suggest that CUC1 positively regulates SAM formation not only through STM but also through an STM-independent pathway that is negatively regulated by AS1 and AS2. ..
  6. Abe T, Hashimoto T. Altered microtubule dynamics by expression of modified alpha-tubulin protein causes right-handed helical growth in transgenic Arabidopsis plants. Plant J. 2005;43:191-204 pubmed
  7. Kim H, Yano A, Wada Y, Sano H. Properties of a tobacco DNA methyltransferase, NtMET1 and its involvement in chromatin movement during cell division. Ann Bot. 2007;99:845-56 pubmed
    ..Results also revealed that NtMET1 becomes localized to the vicinity of chromatin with the aid of Ran GTPase during cell division, and may play an important role in progress through mitosis independently of methylation activity. ..
  8. Nishizawa A, Yabuta Y, Shigeoka S. Galactinol and raffinose constitute a novel function to protect plants from oxidative damage. Plant Physiol. 2008;147:1251-63 pubmed publisher
    ..These findings suggest the possibility that galactinol and raffinose scavenge hydroxyl radicals as a novel function to protect plant cells from oxidative damage caused by MV treatment, salinity, or chilling. ..
  9. Tamoi M, Tabuchi T, Demuratani M, Otori K, Tanabe N, Maruta T, et al. Point mutation of a plastidic invertase inhibits development of the photosynthetic apparatus and enhances nitrate assimilation in sugar-treated Arabidopsis seedlings. J Biol Chem. 2010;285:15399-407 pubmed publisher
    ..These findings suggest that Cys-294 of INV-E is associated with the development of the photosynthetic apparatus and the assimilation of nitrogen in Arabidopsis seedlings to control the ratio of sucrose content to hexose content. ..
