    Plant J 42:133-44. 2005
    ..On the other hand, the mutant phenotype was restored in older seedlings. Arabidopsis probably contains another late general sigma factor, the promoter specificity of which widely overlaps with that of AtSIG6...

    Int Rev Cytol 244:1-68. 2005
    ..They have provided novel insights into the molecular basis of plastid transcription in higher plants. This review summarizes state-of-the-art knowledge of molecular mechanisms that regulate plastid transcription in higher plants...

    FEBS Lett 516:225-8. 2002
    ..The blue light specificity was not observed in the accumulations of remaining five SIG genes. The blue light dependency of the SIG5 expression well explains the light-dependent behavior of the psbD BLRP...
  5. ncbi Blue light-induced transcription of plastid-encoded psbD gene is mediated by a nuclear-encoded transcription initiation factor, AtSig5
    Yuichi Tsunoyama
    Radioisotope Research Center, Kyoto University, Kitashirakawa Oiwake cho, Sakyo ku Kyoto 606 8502, Japan
    Proc Natl Acad Sci U S A 101:3304-9. 2004
    ..We propose that AtSig5 acts as a mediator of blue light signaling that specifically activates the psbD BLRP in response to blue light in Arabidopsis...

    Plant Cell Physiol 48:186-92. 2007
    ..Specific transcripts of rice psbA were synthesized in vitro by reconstituted OsSig5-RNAP holoenzymes. These results indicated that OsSig5 is a plastid sigma factor. This is the first report of the Sig5-type sigma factor in crops...
