Summary The gene of a cytoplasmic 18 S ribosomal RNA (18 S rDNA) of the dicotyledonous plant tomato (ycopersicon esculentum) cv. Rentita has been cloned, and its complete primary structure has been determined. The tomato 18 S rDNA is 1805 by long with a G+C content of 49.6%. Its sequence exhibits 94%–96% positional identity when it is colinearly aligned with the previously reported sequences of the 17–18 S rDNAs of the dicot soybean and the monocots maize and rice. A model of the secondary structure of the 18 S rRNA of angiosperms is presented and its genera-specific structural features are compared with a current eukaryotic 18 S rRNA consensus model.
