|Gene full name
|Plastid-encoded plastid RNA polymerase sigma factor 2
|Ortholog of Arabidopsis SIG2 gene
|chloroplast, plastid-encoded plastid RNA polymerase, transcription, response to light illumination
|MpSIG2 overexpression has an effect similar to that of MpSIG1 overexpression on the transcript levels of chloroplast genes. Citrine fused with the amino terminal sequence of MpSIG2 is transferred to chloroplasts. MpSIG2 transcript is induced by dark shift and decreased by light illumination.
