The result of sequence analysis indicated that the length of cDNA and DNA fragments of Lectin gene and the length of cDNA and DNA fragments of Pectate Lyase gene were 508 bp,575 bp,1,316 bp and 1,858 bp respectively.The DNA fragment of Lectin gene had a intron,whose length was 67 bp .The DNA fragment of Pectate Lyase gene had 3 introns,whose lengths were 90 bp,83 bp,and 370 bp respectively. All these four introns sequences followed the rule of GT-AG.

Some characteristics of the novel gene YH1 was explored by bioinformatics. The YH1 gene was mapped on the chromosome 20 with the size of 7. 5 kb or so by blasting to genome database and this fragment size for YH1 gene coincided with the result of Souther blot. There were nine exon and eight intron.

利用生物信息学方法，在基因组数据库中比较，发现YH1基因存在于一个定位在20号染色体上7.293kb的DNA序列中，这与Southern blot结果相符。9个外显子被8个内含子隔开。

The sequences of segments of the trnL intron from 29 species and trnL-trnF IGS from 21 species of Magnoliaceae were analyzed. The results from the strict consensus trees were consistent with the former systems ① several species within the genera Michelia were homologious;② the subgenera Yulania was extremely homologious and much far from subgenera Magnolia;③ the species within Manglietia were highly conservative.

通过木兰科29个种的trnL基因内含子的525个碱基序列及21个种的trnL-trnF基因间隔区的370个碱基序列测定和分析，构建的严格一致性树建议：①含笑属为相对一致的单系类群；②玉兰亚属的几个种形成一个单系类群，与木兰亚属的几个种无共衍位点；③木莲属为个相对保守的类群，种间碱基差异很小。

The cloned BBE gene sequences were 94.84% identified with the reported BBE genes in GenBank previously. Based on the cDNA sequences of COR and BBE ,two fragments about 400～500 bp from each gene with lower identity among them were cloned. The fusion gene BC (744 bp) is fused by the PCR technique. Then the promoter CaMV 35S driven, containing'forward BC fusion fragments-reverse pdk intron-reverse BC fusion fragments', plant siRNA expression vector were constructed based on the vectors pHANNIBAL and pART27.The work will lay the foundation for breeding a low morphine and high thebaine poppy.
