InterPro : IPR016262

Name  RNA polymerase sigma factor, SigB/SigC/SigD, plastid Short Name  RNA_pol_sigma_SigB/C/D_plastid
Type  Family Description  This entry represents certain plastid RNA polymerase sigma factors, including SigB, SigC and SigD [, ]. Development of plastids into chloroplasts is triggered by light. The coordination of light-induced plastid gene expression is directed by both nuclear and plastid genomes. Plastid DNA is transcribed by at least two types of RNA polymerase, plastid-encoded RNA polymerase (PEP) and nuclear-encoded RNA polymerase (NEP). Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. Sigma factor SigB appears to play a critical role in the coordination of the two genomes for chloroplast development [].
