生物型

Results Five DFRs were found. One of the DFR of 383 bp was specific to biovar antiqua. The 383 bp fragment was only found in strains of Y.pestis isolated from Marmota baibacina Spermophilus undulates Plague Focus of the Tianshan Mountains, but not found in strains from other Plague Foci. It was also found in two (belonging to biotypeⅠ and Ⅱ) of five strains of Y.pseudotuberculosis .

结果 发现了5个在不同生物型鼠疫菌间存在差异的DNA片段，其中一个383bp的片段在来自天山山地灰旱獭、长尾黄鼠鼠疫自然疫源地的30株鼠疫菌全部阳性，而来自其它鼠疫自然疫源地的菌株全部阴性，5株假结核耶尔森菌中有2株阳性。

Why that should be true only for this particular biotype is unknown. Finding the answer would make a lot of farmers happier.

但是，为什么只有这种特殊的生物型出现了该种情况还不得而知，因此，解答这一难题将使千千万万的农民受益。

The quality of biotype fertilizer I treatment rice better than other treatments, but didn't reach notable leave.

生物型I处理产量显著高于其他处理，水稻品质好于其他处理，但未达到显著水平。

The yield of biotype fertilizer I treatment is higher significantly than other treatments.

减少化肥用量的生物型肥处理与常规施肥相比，氮、磷、钾的利用率分别提高11.8%、18.9%和26.6%。

In summery, this study has proved that biotype in BPH is a very complex phenomenon, and the quantitative resistance does really exist in rice varieties.

各类生物型都不是遗传上同质的单一群体，而是具有某种特异遗传构成和特异平均致害表型的混合群体。

O139 serogroup and O1 El Tor biotype kept close inherent identity in evolution, and it is possible for O139 to evolute from O1 El Tor.

O139群与O1群El Tor型存在密切的种系进化关系，前者可能由O1群El Tor生物型进化而来。

As the rapid development of contemporary biochemistry technology, new-style beautiful breast cosmetic is increasing also, apparent to beautiful breast effect biochemistry additive appears ceaselessly, if placenta extracts albumen of content, royal jelly, collagen, serum to wait, curative effect of product of these biology beautiful breast is apparent and safety does not have side-effect; Product of the natural plant that is a delegate with Chinese herbal medicine beautiful breast its characteristic is safety, effect good, cost is low; Have already in product of a few series can make make the same score pectoral ridgy abundant breast element, have again in the light of Female The bounce elite element with flabby, flagging breast, still have gel of be good at bosom, agent of sparge of be good at bosom.

随着现代生化技术的迅速发展，新型的美乳化妆品也越来越多，对美乳效果明显的生化添加剂不断出现，如胎盘提取物、蜂王浆、胶原蛋白、血清等，这些生物型美乳产品疗效明显且安全无副作用；以中草药为代表的天然植物型美乳产品其特点是安全、效果好、成本低；一些系列产品中既有可使平胸隆起的丰乳素，又有针对女性乳房松弛、下垂的弹力精华素，还有健胸凝胶，健胸喷雾剂等。

Therefore, its morphological identification, test of the squash silverleaf induced as well as two genetic markers (RAPD-PCR and rDNA-ITS1) were carried out in order to establish a base for effective control.

此外还对北京地区B型烟粉虱田间的发生情况做了初步调查。搞清我国烟粉虱生物型的种类及其分布是采取有效防治措施之前迫切需要解决的问题。

The B biotype of Bemisia tabaci, sometimes called a "super bug", has been one of this species complex's most harmful biotypes because of the tremendous damage it inflicts worldwide.

B型烟粉虱是烟粉虱复合种下危害最为严重的一个生物型，现已成为一种世界性的害虫，被称为&超级害虫&。

The results are summarized as follows:From 2004 to 2008, field investigation was conducted in 19 locations which differ in terms of frequency of transport activities in Zhejiang, 11652 whitefly individuals collected from 154 plots were analyzed by RAPD PCR and mtCO1 sequencing to determine their genotypes. The results revealed the presence of at least 5 genotypes of B. tabaci in Zhejiang, and each genotype has its own distribution.

主要研究结果如下：2004年至2008年，本研究在浙江省内对按交通发达程度选择的19个有代表性的地点进行了连续5年的田间调查，通过RAPD-PCR和线粒体CO1测序方法对154个样块中11652头烟粉虱进行生物型鉴定，结果显示，浙江省内至少存在5个烟粉虱遗传型，且具有各自特定的分布区域。
