The nucleotide sequences of chloroplast 4.5 S rRNAs from four species of plants, celery (Apium graveoleus), barley (Hordeum vulgare), Chinese chive (Allium tuberosum) and dayflower (Commelina communis)

摘要

>Four chloroplast 4.5 S rRNAs were isolated from the respective plant leaves by a simple method. The complete nucleotide sequences were determined using rapid gel sequencing techniques. The sequences are highly conserved among chloroplast 4.5 S rRNAs. The 4.5 S rRNAs of celery, Chinese chive and dayflower are 103 nucleotides long and that of barley 95 nucleotides long. The 7-nucleotide sequence from position 28–34 is absent in monocotyledon barley 4.5 S rRNA but is present in monocotyledon Chinese chive and day-flower.
