Figure 4From: Identification of genes differentially expressed in dorsal and ventral chick midbrain during early DevelopmentA phylogenetic tree showing the relationships of the QR1-like genes. Multiple sequence alignments were generated using PileUp from the GCG Wisconsin package (Version 10.3, Accelrys Inc., San Diego, CA) and ClustalX [66]. Phylogenetic analyses were performed on an alignment of 250 amino-acids using the neighbour-joining method [67] with 1,000 pseudosamples, as implemented in PAUP* [68].Back to article page
