Not AvailableSingle nucleotide polymorphisms (SNPs) represent stable, bi-allelic
nucleotide variations that are distributed throughout the genome and are
the most abundant genetic variation. The present study targeted SNP
related molecular differentiation and phylogenetic relationship of Indian
Helicoverpa armigera populations by using expressed sequence tags (ESTs)
of partial cytochrome oxidase subunit I (COI). The phylogenetic evaluation
clearly separated the northern and southern Indian populations of H.
armigera with little admixtures of central Indian populations. The SNP
mining also revealed two major clusters as that of phylogeny with a total of
11 potential SNPs, of which 10 were in reliable haplotypes. The potential
SNPs were found to contain eight transitions, three transversions and no
indels (insertions and deletions). Out of 38 sequences, 13 were haplotypes
in which 4 were single haplotypes. In cluster 1, the reliable bi-allelic SNPs
were observed at 97, 166 and 265 nucleotide positions; while they were at
411, 423, 522, 655 and 656 positions in cluster 2. The present study highlighted
the genetic polymorphism and relationship of Indian H. armigera,
besides confirming the long distance migration and gene flow between the
geographic populations.Not Availabl
