摘要: 根据美洲黑杨PdZFR部分cDNA序列,采用拟基因组文库步行法和RACE克隆了该基因全长cDNA及基因组DNA, 并对该基因的启动子、转录起始位点、内含子分布、剪切方式、编码的氨基酸序列和该基因在染色体上的分布位置进行了分析。组织或器官特异表达分析表明:该基因与植物发育相关。Abstract: The full length cDNA and genomic DNA of PdZFR were cloned from Populus deltoides by RACE and Visual Genome Library Walking methods respectively, according to its partial cDNA sequence. Meanwhile, the gene promoter, transcription initiation, intron and exon distribution, spice pattern, the amino acid sequence encoded and the location of this gene on chromosome were analyzed. The tissue or organ-specific expression analysis showed that this gene was related to plant development.
