| 摘 要： | 从海桐中克隆得到苯丙氨酸解氨酶(PAL)基因cDNA片段,并命名为PitPAL,GenBank登录号为AY747678。PitPAL长866个bp,编码289个氨基酸。通过核苷酸和蛋白质序列多重比较发现PitPAL与其他植物的PAL基因高度同源。PitPAL编码的蛋白质序列包含与水稻、玉米PAL蛋白质相同的脱氨基位点和催化活性位点。PAL系统进化树表明PitPAL与乔木类植物(如夹竹桃、山茶)的PAL基因聚类关系最近。PitPAL基因的克隆为利用基因工程技术来调控海桐花青苷的合成代谢、以及海桐花的颜色调控提供了基因资源。 |

| Abstract: | A phenylalanine ammonia-lyase(PAL) gene(designated as PitPAL) was cloned from Pittosporum tobira.The PitPAL cDNA fragment was 866bp and it encoded a 289 amino acid protein.PitPAL was found to have extensive homology with those of other plant PAL genes via multiple alignments.The domination sites and catalytic active sites in PAL protein of Oryza sativa and Zea mays were also found in PitPAL.Phylogenetic tree analysis revealed that PitPAL had closer relationship with PALs from arbor plants than from other plants.The arbor plant is Nerium oleander and Camellia sinensis.PitPAL is a useful tool to study the regulation of anthocyanin metabolism in P.tobira. |
