Characterization of the 16S PC promoter. 16S precursor RNAs have been analyzed by primer extension using total RNA prepared from different plant materials. A, Dry seeds (lane 1), seeds after imbibition (lane 2), and leaves from mature Arabidopsis plants (lane 3). B, Dry seeds (lanes 1 and 4), seeds after vernalization (lanes 2 and 5), and plantlets 2 d after germination (lanes 3 and 6) of wild-type (lanes 1–3) and rpoTmp plantlets (lanes 4–6). C, Dry seeds (lanes 1 and 4), seeds after vernalization (lanes 2 and 5), and plantlets 2 d after germination (lanes 3 and 6) of rpoTp (lanes 1–3) and wild-type plantlets (lanes 4–6). D, Seeds of the tt2-1 mutant have been germinated and grown in the absence (−) or presence (+) of Tagetin and total RNA has been prepared 1 d after germination. 16S precursor RNAs have been analyzed by primer extension. The insert on the left shows a longer exposure of the PC-initiated rrn transcript.
