Phylogenetic analysis of deduced amino acid sequences.

<p>Phylogeny of <i>WsCPRs</i> was inferred using the Neighbor-joining method using MEGA 5 software. A total of 33 protein sequences used for analysis were from following plant species: <i>Withania somnifera</i> (WsCPR1: HM036710, WsCPR2: GU808569), <i>Petunia hybrida</i> (CPR1: DQ099544, CPR2: DQ099545); <i>Petroselinum crispum</i> (CPR1: AF024635, CPR2: AF024634); <i>Gossipium hirsutum</i> (CPR1: FJ719368, CPR2: FJ719369); <i>Populus trichocarpa</i> (CPR1: XM_002307300, CPR2: XM_002329600, CPR3: AF302498); <i>Arabidopsis thaliana</i> (CPR1: X66016, CPR2: X66017); <i>Capsicum annuum</i> (EU616557); <i>Vigna radiata</i> (P37116); <i>Vicia sativa</i> (Z26252); <i>Stevia rebaudiana</i> (DQ269454); <i>Ricinus communis</i> (XM_002514003); <i>Pisum sativum</i> (AF002698); <i>Picrorhiza kurroo</i>a (JN968968); <i>Artemisia annua</i> (EF104642); <i>Papaver somniferum</i> (U67185); <i>Taxus cuspidate</i> (AY571340); <i>Taxus chinensis</i> (AY959320); <i>Perilla frutescens</i> (GQ120439); <i>Ophiorrhiza pumila</i> (AB086169); <i>Medicago truncatula</i> (XM_003610061); <i>Lotus japonicas</i> (AB433810); <i>Catharanthus roseus</i> (Q05001); <i>Centaurium erythraea</i> (AY596976); <i>Zea mays</i> (CAC83301); <i>Triticum aestivum</i> (AGC27711) and <i>Eschscholzia californica</i> (U67186). All CPRs were grouped into two clusters where the WsCPR1 and WsCPR2 confined to their corresponding cluster like other CPRs.
