As a critical enzyme in secondary metabolism of plant,Phenylanlanine ammonialyase(PAL) has significant meaning to its development and strong tolerance ability against hard.A full-length cDNA of PAL gene was isolated from Phyllostachys edulis through RT-PCR and RACE methods,and named as PePAL1(GenBank accession number:FJ195650).PePAL1 is 2 436 bp,which contains an open reading frame encoding 701 amino acids.The results of amino acid sequence analysis showed that PePAL1 had high identities with other gramineous PAL in Oryza sativa,Zea mays,Saccharum officinarum,Bambusa ventricosa,Bambusa oldhamii and Triticum aestivum,especially with PAL from O.sativa up to 93.0%.Phylogenetic analysis showed that PePAL1 and LLB1 were on different branch sites.Tissue specific expression showed that PePAL1 expressed in leaf,sheath,stem and root,much higher in stem.
