Identification of cis-acting RNA leader elements required for chloroplast psbD gene expression in Chlamydomonas.
The psbD mRNA of Chlamydomonas reinhardtii is one of the most abundant chloroplast transcripts and encodes the photosystem II reaction center polypeptide D2. This RNA exists in two forms with 5' untranslated regions of 74 and 47 nucleotides. The shorter form, which is associated with polysomes, is likely to result from processing of the larger RNA. Using site-directed mutagenesis and biolistic ...
متن کاملThe RNA Structure of cis-acting Translational Elements of the Chloroplast psbC mRNA in Chlamydomonas reinhardtii
Photosystem II is the first of two light-driven oxidoreductase complexes in oxygenic photosynthesis. The biogenesis of photosystem II requires the synthesis of polypeptide subunits encoded by the genomes in the chloroplast and the nucleus. In the chloroplast of the green alga Chlamydomonas reinhardtii, the synthesis of each subunit requires interactions between the 5' UTR of the mRNA encoding i...
متن کاملcis- and trans-Acting determinants for translation of psbD mRNA in Chlamydomonas reinhardtii.
Chloroplast translation is mediated by nucleus-encoded factors that interact with distinct cis-acting RNA elements. A U-rich sequence within the 5' untranslated region of the psbD mRNA has previously been shown to be required for its translation in Chlamydomonas reinhardtii. By using UV cross-linking assays, we have identified a 40-kDa RNA binding protein, which binds to the wild-type psbD lead...
متن کاملSelectable Marker Gene Removal and Expression of Transgene by Inducible Promoter Containing FFDD Cis-Acting elements in Transgenic plants
Abstract Background: Selectable marker gene (SMG) systems are critical for generation of transgenic crops. Transgenic crop production Background: Selectable marker gene (SMG) systems are critical for generation of transgenic crops. Transgenic crop production without using SMG is not economically feasible. However, SMGs are non-essential once an intact transgenic plant has been established. Eli...
متن کاملIdentification of cis-regulatory elements required for larval expression of the Drosophila melanogaster alcohol dehydrogenase gene.
The Alcohol dehydrogenase (Adh) genes of two distantly related species, Drosophila melanogaster and Drosophila mulleri, display similar, but not identical, patterns of tissue-specific expression in larvae and adults. The regulatory DNA sequences necessary for wild-type Adh expression in D. mulleri larvae were previously reported. In this paper we present an analysis of the DNA sequences necessa...
