Cloned(Commentary)

Cloned (Comment) Organism
gene rpoA, recombinant expression of the HA-tagged alpha-subunit in transplastomic tobacco plants, analysis of the distribution of the tagged polymerase in plastid subfractions, and associated genes are identified under various light conditions. RpoA:HA is detected as early as the 3rd day after imbibition, and is constitutively expressed in green tissue over 60 days of plant development. Phenotypes of tagged RpoA and wild-type control lines, overview. Transplastomic tobacco plants grown on soil are phenotypically indistinguishable from wild-type Nicotiana tabacum

chloroplast light-dependent, plastome-wide association of the plastid-encoded RNA polymerase with chloroplast DNA. The polymerase alpha-subunit preferentially associates with the plastid membranes, and is less abundant in the soluble stroma fraction Nicotiana tabacum 9507

chloroplast membrane attachment of RpoA:HA to the membrane fraction during early seedling development is independent of DNA, but at later stages of development, DNA appears to facilitate attachment of the polymerase to membranes Nicotiana tabacum 31969

General Information

General Information Comment Organism
physiological function plastid genes are transcribed by two types of RNA polymerases: a plastid-encoded eubacterial-type RNA polymerase and nuclear-encoded phage-type RNA polymerases, spatio-temporal expression of plastid RNA polymerase. The association of plastid RNA polymerase with photosynthesis-related genes is reduced during the dark period, indicating that plastome-wide plastid RNA polymerase-DNA association is a light-dependent process Nicotiana tabacum
