Evidence for the Nucleotide Sequence of 5‐S rRNA from the Flowering Plant Secale cereale (Rye)

Abstract
Evidence for the sequence of rye 5-S rRNA was derived from the analysis of partial and complete enzymic digests of the 32P-labeled molecule. The probable sequence of 5-S rRNA from 4 other flowering plants was deduced by aligning, with the homologous sequences in the rye 5-S rRNA, oligonucleotides produced by T1 [EC 3.1.4.8] and pancreatic A [EC 3.1.4.16] ribonuclease digestion. The most dissimilar differed in only 7 positions. From a comparison of the sequence of rye 5-S rRNA with those known for other types of organism, it was possible to distinguish some structural features of the molecule which are common to all of them. Also, information was obtained about the possible phylogenetic relationship of the flowering plants to other organisms [Chlorella pyrenoidosa and Torulopsis utilis] whose 5-S rRNA has been sequenced.
