Abstract Chloroplast 4.5 S rRNAs of the monocotAcorus calamus and the dicotLigularia calthifolia have been sequenced. Phylogenetic trees for the chloroplast 4.5 S and 5 S rRNAs and also for cytosol 5 S rRNAs have been constructed by several methods. They are compared with previous studies. Evidently, it is necessary to consider the inequality of nucleotide substitution rates in different lines for adequate phylogenetic reconstructions. Some relevant conclusions are presented. The possibilities and prospects for using data on low-molecular-weight rRNAs from cytosol and organelles for deducing phylogenetic relationships in plants are discussed.
