Allium sativum, belongs to a member of the onion family (Alliaceae) are economically important vegetables because of the culinary value and medicinal purpose. Using PCR strategy with degenerated primers targeted to conserved regions of orthologous phenylalanine ammonia-lyase (PAL) and cinnamate 4-hydroxylase (C4H) sequences available, full-length PAL and C4H from A. sativum. The amino acid sequence of these genes is highly conserved, particularly AsPAL and AsC4H has greater than 70% amino acid identity to other plants. AsPAL and AgC4H were most highly expressed in roots of A. sativum, whereas lowest level of transcript was detected in flower. Phenolic compounds most highly produced in flowers of A. sativum. The presented sequences and expression an alysis of PAL and C4H will provide possible material to enhance the understading of phenolic compounds synthesis in A. sativum.
