Because Alantean farmers and their scientists had genetically engineered most species to be seedless, the crops could not regenerate nor did enough of the population have seeds to replant their gardens.

因为亚特兰蒂斯农夫和其科学家已基因改造了大部分物种而没有种子，所以就既不能再生农作物，也没有足够多人口拥有种子以重新耕种。

The FDA requires a full evaluation of a genetically engineered food crop when uncharacterized DNA sequences are used, or when food products may contain significantly altered nutrient levels, different compositions from substances currently found in foods, allergenic proteins, new antibiotic resistance markers, or levels of toxins significantly above those found naturally in edible varieties of the same species.

当使用不明特征DNA时或者当食物产品营养水平可能显著改变的、有不同于目前食品中组成成分的、有过敏原蛋白的、有新抗菌素抗体标记的或者毒素水平显著超出同物种可食用各品种中天然存在的这些情况出现时，食品药物管理局将要求完整评估一种基因工程处理过的粮食作物。

Part 4: Brain-derived neurotropic factor genetically modified olfactory ensheathing cells of the neonatal rat Objective To culture the olfactory ensheathing cells from the neonatal rat and modify them genetically by human Brain-derived neurotropic factor to increase the formation of neurophic factors. Methods The OECs were dissociated from the neonatal rat olfactory bulbs and purified with time-speed difference stick.

第四部分：脑源性神经营养因子基因转染新生大鼠嗅鞘细胞目的为提高嗅鞘细胞(Olfactory ensheathing cells，OECs)分泌脑源性神经营养因子(BDNF，Brain-derived neurotropic factor)的能力，探讨将外源性BDNF基因转染入OECs，为今后采用BDNF基因修饰的OECs移植治疗SCI奠定基础。

There were only three invasive alien plant species out of 24 investigated plant species occurred in core zone, which were clearly lower than those of experimental and buffer zones. The invasive alien plant species accounted for 12.5% of total plant species. The invasive alien plant species with the largest comprehensive values of dominance were Peperomia pellucida and Ageratum conyzoides.

在核心区的样方内共调查到了24种植物，外来入侵植物有3种，占植物总数的12.50%，入侵植物数量明显低于实验区和缓冲区，优势度综合值最大的外来入侵植物是草胡椒Peperomia pellucida和胜红蓟。

Nigra, B. oleracea and B. carinata belonged to class 2A according to the classification of karyotypes by Stebbins (1971). According to Levitzky's and Stebbin's view, the more asymmetric karyotype a species has, the more evolved it is. Therefore, B. campestris is the furthest evolved species among the elementary species, and B. juncea and B. napus the furthest among the amphidiploid species. Compared with the previous reports, there is no any cytoplasm in the chromosome sample prepared using this protocol which is very useful for the karyotype analysis, as well as the FISH research on Brassica species.

对上述研究结果分析表明：（1）芸薹属复合种是由基本种相互杂交而成；（2）B基因组与A或与C基因组亲缘关系较远，而A和C基因组亲缘关系较近；（3）芸薹属复合种在演化过程中，发生了染色体结构上的重排现象；（4）芸薹属复合种演化过程中，rRNA基因位点发生了减少；所获结果与国外同类报道相比表明：国内的白菜型油菜存在新的rRNA基因位点，即rRNA基因在芸薹属同一物种不同的品种间具有多态性；有关这类研究国内尚未见报道。
