    • The present invention provides methodologies, including the utilization of genetically modified (GM) tobaccos, for the development and production of consumer acceptable PREPs encompassing the following: 1) production of low tar-to-nicotine ratio cigarettes, which allow smokers to obtain satisfying amounts of nicotine more efficiently than conventional cigarettes while reducing whole smoke deliveries; thereby reducing smoker "compensation" that exists with conventional low-yield cigarettes; 2) reduction of harmful tobacco-specific nitrosamines in tobacco products by genetic means and by extracting nicotine from tobacco and combining such with genetically modified reduced-nicotine tobacco; 3) production of improved expanded tobacco which utilizes genetically modified increased-nicotine tobacco; and 4) production of reconstituted tobacco which includes any combinations of the following: genetically modified increased-nicotine tobacco, genetically modified reduced-nicotine tobacco, tobacco leaf fractions, and freshly harvested freeze-dried tobacco.
    • 本发明提供方法,包括利用转基因(TK)烟草来开发和生产消费者可接受的PREP,包括以下内容:1)生产低焦油至尼古丁比的香烟,其允许吸烟者获得令人满意的量 的尼古丁比传统香烟更有效,同时减少全烟排放; 从而减少传统低产卷烟所存在的吸烟者“补偿”; 2)通过遗传手段减少烟草制品中有害的烟草特异性亚硝胺,并从烟草中提取尼古丁,并与转基因还原尼古丁烟草相结合; 3)生产改良的扩大烟草,利用转基因烟草烟碱; 和4)生产重组烟草,其包括以下任何组合:经遗传修饰的增加尼古丁烟草,经遗传修饰的还原尼古丁烟草,烟叶部分和新鲜收获的冷冻干燥烟草。

    • An improved route is provided for the production of seeds capable of forming F1 hybrid plants of a crop which is capable of undergoing cross-pollination while utilizing self-incompatibility. A substantially randomly mixed population of parent plants is utilized that are substantially incapable of undergoing self-pollination under conventional growing conditions wherein the inability to undergo self-pollination is attributable in each of the parent plants to at least one heterozygous dominant genetic determinant for sporophytic self-incompatibility that is different in each parent. All plants are capable of serving (1) as seed parents which following cross-pollination with pollen from the other parent plants bear seeds capable of forming F1 hybrid plants of a predetermined cultivar, and (2) as pollen parents for other parent plants. The non-selective simultaneous harvest by conventional means from both parent plants of seed capable of forming a single predetermined cultivar of F1 hybrid plant is made possible. The resulting product exhibits heterosis that makes possible increased yields for the grower. In a particularly preferred embodiment the crop is canola-quality Brassica napus.
    • 提供了一种改进的途径,用于生产能够形成F1混合植物的种子,其能够在使用自交不亲和性的同时进行异花授粉。 使用基本上随机混合的亲本植物群体,其在常规生长条件下基本上不能进行自花授粉,其中不能进行自花授粉可归因于每个母本植物中的至少一种对于孢子体自身的杂合优势遗传决定簇 - 不相容性,在每个父母不同。 所有植物能够服务于(1)作为种子父母,其后与来自其他亲本植物的花粉进行异花授粉能够形成能够形成预定品种的F1杂交植物的种子,和(2)作为其他亲本植物的花粉父母。 可以通过常规方法从能够形成F1混合植物的单一预定品种的种子的两种亲本植物进行非选择性同时收获成为可能。 所得到的产品显示出杂种优势,使种植者的产量增加。 在特别优选的实施方案中,作物是油菜品质的甘蓝型油菜。
