The nucleotide sequences of the PAP gene and PAPⅡ gene in the root of Phytolacca americana were determined by reverse transcription polymerase chain reaction and PCR. The gene comprises 942bp and 933bp respectively, encoding 313 amino acids and 310 amino acids. When PAP gene and PAPⅡ gene sequences in the root were compared with those in the spring leaves and summer ones, the highest similarity 100% and 99. 8% were observed respectively. They both had one open reading frame . Analysis of the two sequences showed, in fact, they belonged to one species.

以美洲商陆根为材料，提取其总RNA、反转录，用一对PAP基因的特异性引物和一对PAPⅡ的特异性引物，分别对反转录产物进行PCR扩增，将扩增的目的片段进行序列分析，结果扩增出来的PAP基因与已经报道的序列完全相同，扩增出来的PAPⅡ基因与已经报道的序列同源性也在99.8％，而且它们都各自编码一个开放阅读框架，可以说美洲商陆根中肯定存在PAP和PAPⅡ基因，并已经转录。
