查询词典 isolates

Reaction of 24 Einkorn accessions to mixed inoculum of powdery mildew and stripe rust,and two T.urartu accessions UR204,UR206 and a T.monococcum accession MO205 were used for reaction to a set of 15 differential Blumeria graminis tritici isolates and 21 differential Puccinia striiformis isolates,respectively.Among them,UR206 was resistant to all 15 isolates,UR204 was resistant to 14 isolates except E11,and MO205 showed different resistant types.The results indicated that most likely UR206 and UR204 carried new powdery mildew resistance genes that were different from 18 known Pm genes and MO205 carried new stripe rust gene that were different from 24 known Yr genes.

Isolates isolated from maize and 3 isolates from rice, wheat, adzuki bean in ten provinces were identified as Curvularia lunata. Based on the culture characters, such as color of colony, aerial myeelia, the number of conidia, there were some difference among 43 isolates. Meanwhile, five types of conidium were compared in culture characters and virulence. In each single conidia culture there were different morphic conidia also and no difference in virulence was found among five single-conidium cultures.

收集并分离我国10个省的玉米叶斑病病原物40个以及水稻、小麦、红小豆上的C.lunata分离物3个；对分离物进行培养性状、产孢能力及形态特征的研究结果表明：分离物在菌落颜色、气生菌丝的繁茂程度、产孢量的多少等方面存在明显的差异；同一分离物内分生孢子在形态方面有差异，不同形态单孢继代培养后仍出现多种形态分生孢子，但各单孢培养系在致病力上无差异。

They shared the highest homology to "world-B" group isolates in Brassica pathotype (between 91.8% and 100%). Phylogenetic analysis based on the CP gene sequences of TuMV strains or isolates showed that these 6 TuMV isolates from Shandong belonged to "world-B" group.

所得6个分离物的CP基因的核苷酸序列同源性较高，在97.0%～99.4%之间，系统进化分析表明：它们与Brassica致病型分离物中的world-B组分离物的同源性最高（91.8%～100%），亲缘关系最近，从而从分子水平上将TuMV山东分离物划分为world-B组。

Results Several amino acid substitutions located in antigenic sites or receptor binding sites were found more in the isolates than the current vaccine virus or the isolates from previous year. Amino acid substitution was found in 3, 140, 142, 144, 145, 158, 159, 189, 192, 193, 198, 204, 225, 226 and 227 positions in the isolates during 2003-2008, more amino acid substitutions took place in antigenic determinant A, B and receptor binding site.

结果 每个流行期分离的毒株都较当年的疫苗株或前一年的毒株出现了位于不同抗原决定簇或者受体结合位点的氨基酸替换。2003-2008年不同流行期分离株在3，140、142、144、145、158、159、189、192、193、198、204，225、226和227位点氨基酸发生了变化，多数的改变发生在抗原决定簇A、B及RBS。

Methods Two arrays of isolates were used to evaluate the reliability of ChromID ESBL. One array contained 285 clinical isolates in which the ESBLs-producing feature was screened by confirmatory tests recommended by Clinical and laboratory Standards Institute. The other array contained 28 enterobacterial isolates with their ESBLs gene and producing enzyme feature being confirmed previously.
