本发明揭示了一种确定舞毒蛾基因型的方法。该方法始于从候选舞毒蛾中分离基因组DNA,将该DNA暴露于来自SEQ ID NOs:3、4、5、6、7或其互补物和与SEQ ID NOs:4和5或其互补物足够相似的寡核苷酸引物中的一种,在允许放大基因组DNA的条件下,将放大的DNA与控制样品产生的放大DNA进行比较。根据哪个控制样品放大的片段类似于候选样品中的片段,为候选蛾分配基因型身份。本发明还揭示了一种获取用于确定候选舞毒蛾基因型的DNA引物的方法。该方法包括从亚洲蛾DNA和北美/欧洲蛾DNA中获取片段FS-1、FS-2或FS-3的DNA序列,并分析序列以获取能够引导在亚洲和北美/欧洲舞毒蛾DNA样品中产生不同大小的放大产物的引物。

The present invention relates to a method for rapidly detecting quinolone-resistant
Salmonella
spp. The invention also relates to the oligonucleotide primers and probes utilized in the method, which can differentiate mutant strains having one or two single point mutations in gyrA gene or single point mutation in parC gene from wild type strains, respectively. Said primers and probes can be effectively used for detection of nalidixic acid-resistant and/or ciprofloxacin-resistant
Salmonella
strains.

The invention provides an anther-specific expression promoter in plant, wherein said promoter is a promoter of
Oncidium
aureusidin synthase gene OgAS1, and has a sequence as SEQ ID No: 3. The invention provides further a gene expression cassette that comprised a promoter having a DNA sequence as SEQ ID No: 3, and a polynucleotide that encode an open reading frame and is linked to the 3′ end of said promoter, wherein said promoter can activate the transcription of said polynucleotide in an organism containing said gene expression cassette. The invention provides also a gene expression vector that contains a promoter having DNA sequence as SEQ ID No: 3. The invention provides further a process for producing a transgenic plant or part of organ, tissue or cell of said transgenic plant containing the above-described gene expression cassette.
本发明提供了一种植物中的花药特异性表达启动子,其中所述启动子是Oncidium aureus芸香酮合成酶基因OgAS1的启动子,具有SEQ ID No:3的序列。本发明进一步提供了一个基因表达载体,其包括一个具有SEQ ID No:3的DNA序列的启动子和一个与该启动子的3'端连接的编码开放阅读框的多核苷酸,其中所述启动子可以在包含所述基因表达载体的生物体中激活所述多核苷酸的转录。本发明还提供了一个包含具有SEQ ID No:3的DNA序列的启动子的基因表达载体。本发明还提供了一种制备转基因植物或包含上述基因表达载体的器官、组织或细胞的过程。

Disease resistance in domesticated fowl has been associated with the B and Rfp-Y systems of major histocompatability genes. A method for breeding domesticated fowl to produce disease resistant offspring involves selecting at least one parent that has a B genotype, an Rfp-Y genotype or both that is characteristic of disease resistance and mating that parent with a second parent to produce a disease resistant offspring.
