Appearance of L90I and N205S Mutations in Effector Domain of NS1 Gene of pdm (09) H1N1 Virus from India during 2009–2013

<table>Phylogenetic tree of all sequences (120 sequences from India, 2007–2013) of NS1 gene of influenza A (H1N1) was constructed using maximum likelihood method in MEGA 6.0 software. Bootstrap values at 500 replications were shown at branches. Each node showing accession number with strain name. Phylogenetic tree is depicting 4 major clusters or groups represented by their cluster name given in front of each cluster.</table>
