Uses of Random Amplified Polymorphic DNA (RAPD) Markers in the Altitudinal Diversity of Plagiochasma appendicualtum

Arvind Soni, Alka Niveden, Virendra Nath and Anil Kumar    

Abstract: Random amplified polymorphic DNA markers were used to determine the altitudinal variation within and between Plagiochasma appendicualtum collected from different altitude of Western Himalaya especially from Mussoorie region of India. Findings of UPGMA cluster analysis and band frequency of all the nine accessions were separated according to their altitudes supporting to their morphological differences as well. Gene flow and spore dispersal plays an important role in the polymorphism. Gene flow within P. appendiculatum growing on same altitude is very high as compared to accessions collected from different gradient of altitudes i.e., the genotypes collected from same altitude showing not so much polymorphism compared to different altitude. It has been concluded that the RAPD markers would be useful to characterize the altitudinal variation between different accessions of P. appendiculatum and may be also valuable to other bryophytes collected from various environmental condition.
