In this study 24 cpSSR primer pairs were screened, and four pairs were found producing DNA fragment length polymorphism from the tested populations of Castanea mollissima.

对24对cpSSR通用引物进行筛选，选用4对呈现多态性的引物对板栗的4个野生居群和9个地方品种群进行遗传分析。

METHODS: The collagen type Ⅰ gene was cloned by the improved subtractive hybridization, and the fragment of collagen type Ⅰ cDNA was labeled by digoxin and was hybrided by in situ hybridization on the section of capsule of normal and cataractous lens.

用改良的消减杂交法克隆Ⅰ型胶原基因，地高辛标记Ⅰ型胶原cDNA片段制作探针，用原位杂交法研究其在晶状体前囊膜切片上的表达，并作统计学处理。

用改良的消减杂交法克隆Ⅰ型胶原基因，地高辛标记Ⅰ型胶原cDN####段制作探针，用原位杂交法研究其在晶状体前囊膜切片上的表达，并作统计学处理。

The gene polymorphism of 5-HT2A re ceptor was determined in positive schizophrenic cases and normal controls with a mplification restriction fragment length polymorphism technique.

采用AmP-RFLP方法，检测精神分裂症患者和对照组的5-HT2A受体基因频率分布。

The percentages of insect fragment occurrence of various body parts were: antenna, 34.5%; mandible, 8.8%; legs, 43.4%; wings, 5.3%; cerci, 1.8%; and ovipositors, 0.9%.

昆虫碎片经鉴定分析后，各目昆虫碎片样品前三目之百分比分别为，直翅目47.8%、鞘翅目21.7%、革翅目15.2%。

An example was given to demonstrate searching for the homologous gene fragment of 28S rDNA D2 region among the superfamily Chalcidoidea. BlastAlign,GenBank,Chalcidoidea,28S rDNA,D2 region

BlastAlign能够在多条序列两两比对后构建出数据矩阵，从而据此找出序列中最具有代表性即与其它序列遗

No fragment length nor nucleotide sequence differences were detected for 2 chloroplast intergenic spacers between Chilanshan and Alishan populations in both Chamaecyparis species.

结果发现红桧与台湾扁柏於栖兰山与阿里山两族群间，在两个叶绿体DNA之基因间区间序列其限制酶片段长度及核苷酸序列均没有差异。

In this study, 526 base pair DNA fragment of OMT were obtained from Chamaecyparis formosensis. Then the 5' and 3' RACE coupled with the Genome walking were used to clone the full length of CCoAOMT, named CfCCoAOMT. After combining the sequence data, there is a total of 1721 bps in full length including promoter sequence.

本研究於红桧试材中，选殖出526个碱基对之Caffeoyl CoA 3-O-methyltransferase片段基因序列，再经由5'和3' RACE及Genome walking，共获得计有1721个碱基对，包含启动子及基因全长，命名为CfCCoAOMT。

Low genetic variation has probably resulted from the refugial nature of these populations since the last glaciation rather than from recurrent pollen dispersal between Chilanshan and Alishan populations of these 2 Chamaecyparis species. Two Hinfl restriction site differences were found in the trnV-trnM intergenic spacer between C. formosensis and C. taiwanensis. Fragment length difference as well as point mutations in the petG-trnP intergenic spacer between C. formosensis and C. taiwanensis were also found.

如此低的遗传变异可能是因为现今之红桧与台湾扁柏族群为冰河期存在之大族群的残留小族群，而未必是花粉散播所提供之基因交流极为频繁所造成。trnV-trnM基因间区间序列在红桧与台湾扁柏两者间有两个HinfI之酶切点之差异，在PetG-trnP基因间区间序列也发现台湾扁柏与红桧之间有限制酶片段长度及其他点突变。

After inoculating Chenopodium amaranticolor and Vigna sinensis with in vitro transcripts, mutants resulting from the p82 fragment exchanges and wild type virus were observed for phenotypic changes, but the symptoms and host range were not altered.

体外转录物分别接种苋色藜和豇豆，观察互换复制酶变异片段重组体的寄主范围及所造成的症状。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
