The appearance of DNA bands pattern based on the result of primary selection of RAPD orchid Phaius spp.

Abstract

Abstract This study aimed to examine the appearance of the DNA band pattern resulted from the selection of RAPD primers on Phaius spp. namely Phaius tankervillae, Phaius montanus, Phaius collasus and Phaius amboinensis. The research material was performed in the Center for Plant Conservation of the LIPI Bogor Botanical Gardens. Molecular analysis was carried out at the Laboratory of the Center for Horticultural and Tropical Studies IPB using RAPD. The study showed that the 2 primers RAPD OPA 02 and OPA 16 can be used for DNA amplification of orchids Phaius spp (Phaius tankervillae, Phaius montanus Phaius collasus and Phaius amboinensis) because they produce clear DNA bands. The result of PCR amplification on Phaius tankervillae, Phaius montanus, Phaius collasus, and Phaius amboinensis using OPA 02 and OPA 16 primers produced 11 and 9 DNA bands, respectively, with an average of 5 DNA bands per primer. In the band pattern at 800 bp on OPA 02 primers resulting sharp and clear band pattern quality.
