Analysis of genetic variations among pongamia pinnata populations in Gingee hills using dna barcoding technique

The trnL-trnF intergenic spacer of cpDNA has been sequenced from Pongamia pinnata. These sequences were used for phylogenetic study to show the variations and relationships found in species Pongamia pinnata in its diversity of distribution. The results give sufficient evidence to the morphological and genetic relationships and variations found in Pongamia pinnata. The study concludes that no single source of information should be used unequivocally to determine phylogenetic relationships among the closely related but highly diversified taxa associated with the genus Pongamia.
