- A nuclear-encoded sigma factor, Arabidopsis SIG6, recognizes sigma-70 type chloroplast promoters and regulates early chloroplast development in cotyledonsYoko Ishizaki
Faculty of Human Environment, Kyoto Prefectural University, Shimogamo nakaragi cho, Sakyo ku, Kyoto 606 8522, Japan
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...
- Plastid RNA polymerases, promoters, and transcription regulators in higher plantsTakashi Shiina
Faculty of Human Environment, Kyoto Prefectural University, Kyoto 606-8522, Japan
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...

- Blue light specific and differential expression of a plastid sigma factor, Sig5 in Arabidopsis thalianaYuichi Tsunoyama
Radioisotope Research Center, Kyoto University, Kitashirakawa Oiwake cho, Kyoto 606 8502, Sakyo ku, Japan
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...
- Blue light-induced transcription of plastid-encoded psbD gene is mediated by a nuclear-encoded transcription initiation factor, AtSig5Yuichi 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...
- Two novel nuclear genes, OsSIG5 and OsSIG6, encoding potential plastid sigma factors of RNA polymerase in rice: tissue-specific and light-responsive gene expressionYoshiki Kubota
Laboratory of Molecular Genetics, Collage of Agriculture, Ibaraki University, Ami, Inashiki, Ibaraki, 300 0393 Japan
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...
