The results of in situ hybridization showed that the gene of Mdde was expressed mainly in epidermis of the body wall and fat bodies, and no expression signal was detected in tracheae, intestine and musculature. The gene of Mdde in epidermis expressed both in challenged larva and no-challenged larva, whereas the gene of mdde in fat body expressed only in challenged larva.

原位杂交的结果表明：Mdde基因在家蝇幼虫体内主要表达于表皮和脂肪体，在气管、肠和肌肉组织中没有检测到Mdde基因的表达；表皮中Mdde基因在微生物刺激前后均有表达，而脂肪体中Mdde基因经微生物刺激后才表达，刺激前不表达。

But there are no correlations between gene expression and gene expression specificity or gene expression level.

有趣的是，基因的组织特异性和基因的表达量与基因表达的进化则可能没有相关性。

Methods PCR amplification of drug resistance gene abeM was carried out using chromosomal DNA of Ab 35 and Ab 36 clinical isolates as template. PCR product of abeM gene was sequenced. The nucleotide sequences and deduced amino acid sequences were analyzed by BLAST of NCBI. After cells of Escherichia coli KAM32 transformed with a plasmid carrying the abeM gene PCR product, MICs of various drugs were determined by serial twofold dilution method.

以临床分离的Ab 35、Ab 36染色体DNA为模板扩增abeM基因，对abeM基因扩增产物进行DNA测序及同源性分析；将abeM基因扩增产物与载体连接后转化入大肠埃希菌KAM32感受态细胞中，对转化子进行药敏分析。

To protect the identity of orchid cultivar and the right of the breeders, we successfully develop a novel method by the introduction of foreign DNA sequence (27bp) as molecular marker via BioWare low pressure gene gun into Mormodes lawrence and Zygopetalum mackayi. Histochemical GUS transient expression was obtained from aleurone layer and embryo of Zea mays using BioWare low pressure gene gun with acceleration pressure of 50psi. This is the first report on successful transfer into plant tissue using BioWare low pressure gene gun.

本研究的目的为利用核苷酸排列组合之多样性，设计一段27个碱基对序列来代表品种所有者注册资料，经由国人自行研发之生物镓低压基因枪，利用50psi的氦气压力，将设计好DNA序列标志转殖至妖精兰与轭瓣兰品种，使其实生或分生之子代，皆会具有此注册片段，品种权所有者可以具体以PCR或定序分析确认DNA序列标志，作为保障种源权之认证系统。
