Research Abstract

In Asteraceae, we determined and compared the sequence of cDNA of ADH between the taxa with a little number of ADH isozymes and with the many number. Homologous genes are shown more than 90% homology and most substitutions are synonymous. The important functional regions of ADH proteins are preserved without non-synonymous substitutions. Furthermore purifying selection would be rejected by predictive estimation of speed of molecular evolution.
