Evolutionary relationship and gene structure analysis of the AtPATs in <i>Arabidopsis</i>.

<p>The amino acid sequences of the AtPATs were aligned with Clustal X, and the phylogenetic tree was constructed using the neighbour-joining method in the MEGA 5.0 software program. Each node is represented by a number that indicates the bootstrap value. The scale bar represents 0.1 substitutions per sequence position (left). The right side illustrates the exon-intron organisation of the corresponding <i>AtPAT</i> gene. The exons and introns are represented by the green boxes and black lines, respectively. The scale bar represents 1 kb (right).
