  1. It is used as addition agent and thickener for toothpaste, soap and abstersive and coplasticizer for chromosome, pigment stuffing and the raw materials of pottery and porcelain

    用於日化行業作為牙膏肥皂和洗濟劑的添加增稠劑，復寫紙染色體，顏料填料及陶瓷原料的增塑劑。
  2. In addition to avermectins, s. avermitilis produces oligomycin, a strongly toxic compound. gene deletion vector pxl05 was used to disrupt oligomycin polyketide synthase ( pks ) encoding genes ( olma ) in streptomyces avermitilis cz8 - 73, the producer of anthelmintic avermectins b and the cell growth inhibitor oligomycin. olma gene cluster in the chromosome was displaced by deletion allele on the plasmid via double crossover

    本研究以產阿維菌素b和寡黴素的阿維鏈黴菌cz8 - 73為出發菌株，構建了基因缺失載體pxl05 ，並將其轉入cz8 - 73中，通過缺失載體和染色體之間的同源雙交換，對染色體上長達90kb的寡黴素聚酮合酶（ pks ）基因簇（ olma ）進行了缺失。
  3. An aneuploid state in which a third homologous chromosome is present in addition to the normal autosomal pair is called trisomy.

    除了正常染色體對以外，還存在有第二種同源染色體的非整倍體狀態，被稱為三體性。
  4. In this study, systems of rapid propagation of the cultivars such as d. zingiberensis, d. panthaica and d. composite were setup to find the best way to meet the need of producing, and to establish the base of introduction, breeding and cultivar improvement of foreign dioscorea with high diosgenin ; in addition, there are two strategies to obtain polyploids combining with chromosome engineering : screeding natural mutations and mutation breeding were carred out on d. zmgiberensis. exploratively studies were done on rapid propagation of the three dioscorea plants. the result showed : explants of d. pathaica obtained the appreciate propagation efficency on ms + ba1. 0mg / l + naa0. 1mg / l, ms basic medium containing 6. 0mg - 1 ba, l. 0mg - 1 kt and sucrose at 30gl - 1 or 60g1 - 1 was the appreciate medium for microtuberization

    三種薯蕷屬植物離體再生體系培養條件的探索試驗結果表明：黃山藥外植體適宜的增殖培養基為ms + ba1 . 0mg / l + naa0 . 1mg / l ，微型塊莖誘導為ms + ba6 . 0mg / l + kt1 . 0mg / l + 3蔗糖，高濃度的蔗糖含量（ 6 ）能提高微型薯蕷的誘導率，但對其誘導起關鍵作用的還是ba的濃度；菊葉薯蕷增殖效果較好的培養基為ms + ba1 . 0mg / l ，以ms培養基為誘導微型薯蕷的最佳選擇，誘導率可達50 ；盾葉薯蕷最適宜的增殖培養基為ms + ba2 . 0mg / l ，在誘導微型薯蕷的實驗中發現，當ba濃度為6 . 0mg / l和8 . 0mg / l時， 15d左右節間處膨大形成綠色圓球狀小塊，但繼續培養其上則開始分化芽。
  5. In addition, it introduces the characteristics and identification methods of medicinal plants, and latest achievements obtained in chromosome doubling of medicinal plants in recent years

    此外，還介紹了多倍體藥用植物的特徵、鑒定方法以及近些年來藥用植物染色體加倍所取得的最新成果。
  6. In addition, there exists 72. 2 % of the chromosome surface positively stained with r - banding. 4. complementarity of g - and r - banding pattern it is generally accepted that chromosome banding patterns appear closely related to differences in dna base composition, and r - bands correspond to gc - rich dna and g - bands to at - rich dna

    4 . g 、 r帶型的互補性一般認為，染色體的帶紋與其堿基組成密切相關， r陽性帶對應于gc含量豐富的區域， g陽性帶則對應于at含量豐富的區域。
  7. In addition, he has made significant contributions to the mapping and annotation of human chromosome 7, and, identification of many other disease genes

    除此以外，在斷定人類第七組染色體以及許多其他疾病基因，作出了重大的突破。
