查询词典 maintainer

Compare to K type no.1B/1R male sterile line KTSP3314A,homotypic maintainer line TSP3314B and 1B/1R male sterile line K3314A,homotypic maintainer line 3314B at different developmental stages of superoxide dismutase,catalase,peroxidase activity and variety of malondialdehyde content.

利用K型非1B/1R类型小麦雄性不育系KTSP3314A，其同型保持系TSP3314B，以K型1B/1R类型小麦雄性不育系K3314A、其同型保持系3314B为对照，分别对其叶片和穗子在不同发育时期的超氧化物歧化酶、过氧化氢酶、过氧化物酶的活性和丙二醛含量的变化进行测定。

32B is a key Chinese maintainer line used for hybrid rice breeding. However, it isof poor quality because of a high AAC, a high gelatinization temperature, andnon-fragrant. It is known that the AAC, GT and fragrance traits are controlled by the Wx,starch synthaseⅡa and fragrance genes. The quality ofⅡ-32B was improved byintrogressing the Wx, SSⅡa and fgr genes from YixiangB, another maintainer line, that has alow AAC, a low GT and fragrant sensory, with the assistance of the functional markers. TheWx microsatellite [_(17) allele] SSⅡa single nucleotide polymorphism and fgrinsertion/deletion allele (8 bp), were transferred toⅡ-32B by two backcrosses and twoselfings.

通过两次回交和两次自交，并利用功能标记的辅助选择，将来自品质优良保持系宜香B(有香味，低AAC、GT)中Wx-_(17)、SSⅡa-TT和fgr(8bp缺失)等位基因导入到品质较差Ⅱ-32B(高AAC，高GT，没有香味)中，以改良其品质。

The results showed that as the leaves development, POD activity on leaves of the male sterility line significantly differed from that in the maintainer and restorer line. The CAT activity had little difference in tasseling stage, SOD activity in the male sterility line was higher than its maintainer and restorer line, and the difference was significant in every stages.

结果表明：玉米叶片在生长过程中，不育系与保持系和恢复系叶片中的POD活性有明显差异；CAT活性在抽雄期相差不大；不育系每个时期的SOD活性均显著高于保持系。

In this paper, major agronomic traits and grain quality traits affecting rice yield and grain quality were investigated in seven aromatic rice maintainer lines bred in Sichuan and one variety introduced from America. It was aimed at estimating the numbers of gene controlling aroma, the allelism of aroma genes, location of aroma gene on the chromosome, and molecular tagging of aroma gene.

本研究利用四川新育成的七个香稻保持系(D香1B、D香2B、内香2B、内香4B、绵香2B、绵香3B、宜香1B)、一个香稻引进改良品种(泸香90)和一个非香型保持系为材料，研究了香稻保持系主要农艺性状和品质性状对品质、产量的影响，并且通过杂交群体构建对香稻香味性状进行了遗传分析。

This study first discovered it is different in nuclear DNA between Ogura-CMS line and its maintainer in the Brassica crop.

根据测序结果设计了1对特异引物，将M6E7-700标记转化为更稳定的SCAR标记。

We are a maintainer and builder of the international system.

我们是国际社会秩序的维护者和建设者。

There are many reports about analysis of isozymes between male sterile lines and their maintainers, but different crops or varieties in same crop expressed dissimilarly. There were few reports about comparison study of isozymes between male sterile line in cabbage and its maintainer at present. Most reports about analysis of isozymes between male sterile lines and their mainainter were limited 1-2 isozymes.

有关细胞质雄性不育系及其保持系花药同工酶分析的报道已有相当多，但不同作物表现不一样，同一作物不同品种表现也有差异，而且目前有关甘蓝雄性不育系和保持系同工酶比较研究的报道极少，有关细胞质雄性不育系与保持系的同工酶分析的报道多限于1—2种酶。

The genetic distances to resistant gene are 9.6 cM and 10.4 cM, respectively. The resistance to sorghum head smut physiological race 3 may be controlled by two mutual independent nonallelic genes, and there is interaction between them. It is found that molecular markers are easier to find in B population than R population during the screening of SSR markers. It may show the different resistance mechanism between restorer line and maintainer line.

高粱对丝黑穗病菌3号生理小种的抗性可能受2对彼此独立的非等位基因控制，并且基因之间存在着互作；筛选SSR标记时发现，高粱抗丝黑穗病基因的分子标记较易在保持系群体中找到，在恢复系群体中DNA片段多态性较少，表明恢复系和保持系在抗性机制上可能存在差异。
