Abstract/OtherAbstract:
|
In light-grown wheat (Triticum aestivum L.) seedlings, the amount of chloroplast and cytoplasmic ribosomal RNA increased to a maximum in the first leaf near the end of its growth and declined by about 60% in the following 3 days. While total ribosomal RNA was declining, labeled uracil was still incorporated into cytoplasmic ribosomal RNA, but the rate of incorporation into chloroplast ribosomal RNA fell by more than 80%, as did the incorporation of labeled leucine into fraction I protein. Either there is greater replacement of cytoplasmic ribosomal RNA than chloroplast ribosomal RNA in mature leaves, or chloroplasts are able to repress the incorporation of exogenous precursor when there is no net synthesis of RNA. |
