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 *** 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 *** up to 93.0%.Phylogenetic analysis showed that PePAL1 and LLB1 were on different branch *** specific expression showed that PePAL1 expressed in leaf,sheath,stem and root,much higher in stem.
