The objective of this paper was to study from three aspects, respectively: Breeding of transgenic rice restorer line for multiple resistance against bacterial blight, striped stem borer and herbicide; Marker-assisted breeding of pyramiding rice fragrance gene and multiple bacterial blight resistance genes; Molecular mapping of transgene cry1Ab in transgenic rice.

本论文主要开展了三个方面的研究：多抗性(抗白叶枯、螟虫、除草剂)转基因水稻恢复系的培育；水稻香味基因与抗白叶枯基因的聚合育种；转基因水稻中转cry1Ab基因的分子标记定位。

Optimization technology was acetidin: N-hexane (3:7) as low-pole solvent system, methanol: dichloromethane (1:9) as polar solvent system, 20% glycerol filter paper as moisturizer, 14 h age Bacillus subtilis as indicating strain seed on thin layer plate cultivated for 14~18 h, 1% TTC staining time 1~2 h, bacterial mix method suitable to 0.2%~0.6% agar semisolid bouillon culture-medium, bacterial spread method suitable to 1% agar semisolid bouillon culture-medium.

结果：该方法展开系统筛选简单，抑菌斑位置准确、斑点清晰，其优化条件为：以乙酸乙酯：正己烷(3：7)为弱极性展开系统，甲醇：二氯甲烷(1：9)为强极性展开系统，用20%甘油滤纸对湿室保湿，以14h菌龄的枯草芽孢杆菌为指示菌种子液，自显影薄层板36℃培养14~18h，1%TTC显色时间为1~2h，含0.2%~0.6%琼脂的半固体肉汤培养基应使用混菌法生物自显影，含1%琼脂半固体肉汤培养基应使用涂布法生物自显影。

Some strains of the nematode-bearing bacteria were bioassayed for their parasitism. All these bacteria can totally not grow or grows badly on the media incorporating the extracts of pine trees, indicating some substances existing in the trees will harmful to the bacterial strains, which is further convinced by preliminary inoculation showing that single bacterial species will not infect Pinus thugbergii. Hence, the growth and reproduction of the nematode-carrying bacteria, which could produce toxic substances causing the death of the tree cells, is closely related to the nematodes, when they first enter to the trees. In the same time, the activity of bacteria improved the circumstances for which nematodes are living, which in turn will beneficial to the growth of nematodes. Thus, there is a complicated interaction among nematodes, bacteria, and pine trees.

对松材线虫携带的细菌的部分菌株进行了寄生性测定，表明这些细菌在添加松树提取液的细菌培养基中不能生长或基本不能生长，这说明松树体内可能存在某些不利于细菌生长的物质，同时初步的接种试验证实，单独的细菌接种不能感染健康的黑松，因此，线虫携带的致病细菌在最初进入树体时，其生长和繁殖与线虫密切相关，结合细菌产生的毒性物质可造成黑松细胞死亡的情况，说明细菌的生长与线虫有关，同时，细菌的活动改变了线虫在松树内的生长环境，使环境变得有利于线虫的生活，因此，线虫、细菌和松树三者存在着复杂的生物关系。

Bacterial enolpyruvyl transferase is one of the key enzymes acting in the initial stage of peptidoglycan synthesis of bacterial cell walls.

肽聚糖是细菌细胞壁的重要成分，烯醇式丙酮酸转移酶是调节肽聚糖合成初始阶段的关键酶。

Since bacteria multiply themselves by binary fission, often at 20 min intervals at their optimum growth temperature, it is possible for one single bacterial cell to produce over 10 million similar bacterial cells in 12 h.

因而许多细菌通过横二分裂方式进行大量繁殖，在最适宜温度下20分钟繁殖一代，在12时间内一个单体细胞就能产生1千万个细胞。
