The venom of elapid snakes contains a number of small proteins that display a broad spectrum of pharmacological activities.In study on the neurotoxin from the venom gland of Bungarus multicinctus,five cDNA sequences (MNCTL1-a,MNCTL1-b,MNCTL1-c,MNCTL1-d and MNCTL2) encoding two novel proteins were obtained from the total RNA by reverse transcription-polymerase chain reaction.

采用SMART技术和RT-PCR方法，从同一个银环蛇毒腺中克隆到了5 种尚未报道过的心脏毒素类似物全长cDNA序列（MNCTL1-a、MNCTL1-b、MNCTL1-c、MNCTL1-d和MNCTL2）。5种序列中，MNCTL1-b、MNCTL1-c、MNCTL1-d和MNCTL2的长度均为505 bp，包括5′非翻译区32 bp，3′非翻译区212 bp和其余261 bp组成的一个完整开放阅读框；MNCTL1-a 由于3′非翻译区24 bp的缺失，全长cDNA仅为481 bp。

Result Based on directly regenerated plant of in vitro plant of Xinjiang cotton, the cotton epicotyl treated by pre-culture for 3-5 d was immersed in bacteria for 15 min and co-cultured for 2 d. Cephalothin at 100 mg/L was used to inhibit bacteria after 50 mg/L kan selection. And the combination of cytokinin with relatively high content and auxin with low content was used in its directly budding culture to obtain resistant seedlings.

结果］在新疆棉花离体培养植株直接再生植株基础上，经3~5d预培养处理过的棉花上胚轴，在浸菌15 min共培养2 d后，经50 mg/L kan筛选，用1000 mg/L头孢霉素抑菌，并用相对高含量细胞分裂素和低含量生长素的组合对其进行直接出芽培养，从而获得抗性小苗。

Genetic diversity and phylogenetic relationship in goldfish were examined using mitochondrial D-Loop partial sequences at eight representative varieties of goldfishes and wild crucian carp. The eight representative varieties were Red Common Goldfish, Red Fantail, White Oranda with Red Carp, White Pearlscale, Red Tigerhead, Black Moor, Red Moor with Butterfly Tail and Red Bubble-eye with Dorsal Fin. 699 base-pair nucleotide sequences of Mitochondrial D-Loop were examined and analyzed for genetic polymorphism, Sequences data showed that all 129 sequences were grouped into 17 haplotypes. Nine representative varieties shared same haplotype. Five representative varieties of goldfishes had haplotypes respectively.

采用PCR技术扩增了红草金鱼，红文鱼，红顶白高头，白珍珠，红狮头，红龙睛蝶尾，墨龙睛，红水泡八个品种金鱼和野生鲫线粒体DNA的D-Loop区部分序列，PCR产物经纯化、测序、同源序列比对后获得长度为699bp的核苷酸序列，在129个样本中共检测到了17个单倍型，9个品种共享1种单倍型，5个品种的金鱼(BM， MB， WR， RF， RC)检测到各自独有的单倍型。

The results showed that the dinoflagellate genus Symbiodinium clade C was dominant in the study area. Pocillopora damicornis and Favia favus harbor Symbiodinium Clade D, while Galaxeafascicularis and Acropora horrida can harbor more than one type of symbiont.

结果表明鹿回头岸礁造礁石珊瑚共生藻以C系群为优势系群，偶尔发现D系群与鹿角杯形珊瑚和黄癣蜂巢珊瑚共生；另外丑鹿角珊瑚和丛生盔形珊瑚可以同时与C系群和D系群共生。

D-galactoside galactohydrolase (EC3.2.1.23) is usually named lactase which can hydrolyze lactose into galactose and glucose, and also can transfer galactoside.

半乳糖苷酶(B-D-半乳糖苷半乳糖水解酶，β-D-galactoside galactohydrolase，EC3.2.1.23)通常被称为乳糖酶，能将乳糖水解为半乳糖和葡萄糖，并具有半乳糖苷的转移作用。

A novel carbonyl transposition led by anilines'nucleophilic addition to methyl 2-keto α-D-glucopyranoside was discovered. And the mechanism of the reaction concerned to an enol rearrangment was provided through tracing the change of 〓H-NMR and 〓C-NMR of a hemiacetal intermediate which was obtained in the reaction of o-phenylene diamine with 2-keto glycoside. Both the intermediate and the converting product were identified by 〓H-NMR,〓C-NMR,〓H-〓H COSY and HMQC.
