查询词典 tabacum

The plant expression vectors were constructed and two genes were transferred into A. thaliana and N. tabacum, antikanamycin plants were obtained.4. The trials of adventive bud regeneration directly and callus induction was conducted to select out the optimal explants and formula. The results revealed that double scale can produce 13~16 adventive buds per centimeter in MS medium added 10.0 mg/L 6-BA, 1.0 mg/ L NAA, 40 g/L sugar and 7.5 g/L agar. Scale, leaves, scape and different tissue of flower can be induced to produce callus in appropriate medium, but the filament with anther was the optimized explant.

在北京香山樱桃沟野生的十字花科豆瓣菜上发现有芜菁花叶病毒、黄瓜花叶病毒以及一种未报导过的"小白斑"病毒的复合病。小白斑病毒在20多种寄主上，包括十字花科，单独汁液接种时只能产生局部坏死病斑，不能系统侵染；单独接种而能系统感染的寄主有百日菊，只产生极轻微的深浅绿花叶，甚至有时几乎无病状。小白斑病毒能在复合病情况下系统存在于豆瓣菜中是值得注意的一种现象。
