查询词典 mutants

The mutants were further screened through repeated fermentations as well as the measurement of their physical properties. The results showed that some major fermentation indexes of strain HJ1615-d4 such as alcoholicity, fermenting power,total acids and flavoring components etc. were almost the same as those of the original strain. However, its urea yield was only 15.41 mg/L, louer 50 % than that of the original strain.

While doing the RFLP tagging of giant embryogene,the genome changebetween mutants and its original parent,the relationship between RFLP andheteroses in indica,japonica and intermediate rice,the performance of multipleand null allelism in rice varieties,the utilization of null allelic RFLP probes inidentifying indica and japonica rice specifically,the distribution of the nullallelic RFLP probe RG684 in rice cultivars,and the segregations of RFLPmakers in indica/japonica F2 population were also studied.

本实验从经典遗传、分子遗传、育种潜力评估、育种新品系选育等领域，对巨大胚、甜胚乳、暗胚乳三种新型突变体进行了全面系统研究。在对巨大胚进行分子定位过程中，对涉及到的突变体与原始亲本基因组变化，籼、粳、中间型材料的RFLP多态性与杂种优势之间关系，水稻品种的复等位、零等位表现，鉴定籼、粳特异性的零等位RFLP标记，零等位标记RG684在稻种中分布，RFLP标记在籼粳交F2群体中分离等遗传现象也一并进行了分析。

Using Pseudomonas syringae and Pantoea ananas , the dominant ice nucleation active bacteria strains from Yunnan province, as receptors of genetic engineering recombination, and Escherichia coli S17/pZJ25∶∶Tn5 as donator. By transposon Tn5 induced mutants method, the Tn5 was inserted and integrated into the genome of wild type INA + bacteria. INA + mutant as INA - when the linear continuous of INA + gene destroyed.

以云南省冰核细菌的优势种类丁香假单胞菌Pseudomonassyringae和菠萝泛菌Pantoeaananas为重组基因工程菌的受体菌，采用Tn5转座子诱变技术，以大肠杆菌EscherichiacoliS17/pZJ2 5∶∶Tn5作为转座子诱变的供体菌，使Tn5插入并整合到冰核细菌基因组中，使冰核基因的线性连续性被破坏，失去冰核活性。

LFY-like genes play important role in plant development, when they were first isolated from mutants of Antirrhinum and Arabidopsis, they were thought to be "SAM-specific-determinating-genes", regulating the transition from inflorescence to flower meristem. However, further research revealed that LFY-like

LFY类基因在植物形态建成过程中具有重要作用，根据其突变体的特征，曾一度被认为是在花分生组织和花序分生组织中特异表达的"分生组织特征决定基因"，控制花序分生组织向花分生组织的转变。
