Analisis Sekuens Dna Penyandi 18s Rrna Pada Tumbuhan Cocor Bebek (Kalanchoe X Laetivirens)
ABSTRACT
Plant stress studies are based on gene expressions. This research aims to analyze the DNA sequence of 18S rRNA in cocor bebek (K. x laetivirens). The research methods being out are total DNA isolation, electrophoresis, PCR, sequencing and data analysis utilizing BioEdit, BLASTn and Mega 6 programs. Partial DNA sequence of 18S rRNA in K. x laetivirens has been obtaine with 419 bp length. The DNA sequence has 99,28% similarity to K. daigremontiana. Kalanchoe x laetivirens forms one group with another species from the same family based on the DNA sequence of 18S rRNA. A primer pair specific to K. x laetivirens for amplifying 18S rRNA has been designes such as forward 5’- CAA ATT ACC CAA TCC TGA CA -3’ and reverse 5’- CCA ACG TAA ATA GGA TCG AA -3’. The partial DNA sequence of 18S rRNA in K. x laetivirens is potentially being employed as an internal control once the validation process completed.
Keywords: 18S rRNA, housekeeping gene, internal control, Kalanchoe x laetivirens
