ABSTRACT The gene encoding 26S rRNA (26S ribosomal Ribonucleic acid) is part of a large sub-unit of structural ribosomal RNA from eukaryotic ribosomes and is included in the housekeeping gene group that can be used as an internal control in gene expression tests in plants. The aim of this study was to analyze the DNA sequences of 26S rRNA encoding in cocor bebek (Kalanchoe x laetivirens) f…
