摘要:
杜梨(Pyrus betulifolia Bunge)抗逆性强,叶色随季节变化而改变,被广泛用于沿海滩涂景观改造,是园林绿化中常用树种。为了解杜梨色叶相关基因调控途径,对杜梨叶片进行转录组测序,共获得67.7 Gb测序数据,通过组装共得到60 611个基因,其中包含1 059个新基因;与8个功能数据库进行比对分析,共57 669个基因得到了功能注释,注释效率为95.15%;GO分析发现,已注释的差异表达基因共涉及49个功能组,主要集中在膜(细胞组分)、催化活性(分子功能)、代谢过程(生物学过程)等中;KEGG分析发现,差异表达基因主要富集在碳代谢和植物-病原体相互作用等生物学过程中;共筛选出10个与类黄酮相关的基因,分别属于UDPGT等6个基因家族;在杜梨叶片转录组中共筛选出452 501个SNP位点,碱基转换类型所占比例远远高于颠换类型,表明杜梨具有丰富的SNP位点信息。本研究结果可为探究杜梨色叶分子机制等提供理论依据。
