摘要:
多聚半乳糖醛酸酶(polygalacturonase，PG)属于一个大的水解酶家族，它通过降解果胶在植株生长发育过程中的细胞分离事件中发挥重要作用。为深入研究桃PG基因家族的功能，利用生物信息学方法对桃基因组中PG基因家族成员进行鉴定，对其基因和蛋白特征、保守结构域、基因进化树分类和基因表达模式等方面进行研究。结果表明，在桃基因组中共鉴定出了84个PG基因，可以聚类成7个分支A~G；PG基因在8条染色体上呈现不均匀分布，并存在明显的串联重复现象，共发现16个串联重复基因簇；利用 UniGene 数据库进行的组织表达分析。说明有 10 个基因在数据库中有表达数据，其中有6个基因具有组织表达特异性。
