The results obtained from the study on the mode of inheritance ofseveral chloroplast characters in tobacco (Nicotiana tabacum, L.), "as tobring the normal green and the white burley varietics into contrast byusing the diallelcross design are summarized as follows. 1. The inheritance of the chlorophyll content was controlled by thenuclear genes, as it was reported fifty more years ago, but the dominanceof Yb1 and Yb2 was incomplete over Yb1 and Yb2 respectively, since thechlorophyll content of the hybrids was...

The results obtained from the study on the mode of inheritance ofseveral chloroplast characters in tobacco (Nicotiana tabacum, L.), "as tobring the normal green and the white burley varietics into contrast byusing the diallelcross design are summarized as follows. 1. The inheritance of the chlorophyll content was controlled by thenuclear genes, as it was reported fifty more years ago, but the dominanceof Yb1 and Yb2 was incomplete over Yb1 and Yb2 respectively, since thechlorophyll content of the hybrids was always not as high as that of thegreen parents. The inheritance of chlorophyll and that of carotenoid werehighly correlated. 2. The inheritance of lamellate structure in the chloroplast was likelycontrolled by nuclear gene or genes and those of "Burley 21" displayedrecessive in nature. 3. Differences of the "Hill" activity between "Burley 21" and three green varieties were significant and inherited in nuclear pattern. F1hybrids expressed heterosis for the "Hill" activity due to the nuclearheterogeneity between their parents in disputing the effect of cytoplasm. 4. The isoelectric points of eight large subunits of RuBpcase of"Burley 21" were 0.1O—O.12. pH lower than those of "Innovations". Thiswould probably be due to spontaneous differentiation of the chloroplastgenophore occurred synchronically or not synchronically with the geneticmutation from normal green to Burley condition.

利用普通烟草(Nicotiana, tabacum L.)的正常绿叶型烟草和白肋型烟草品种,按安量性状遗传研究的完全双列杂交组合的設计所进行的研究表明:1.烟草叶绿素含量的遗传为部分显性的核基因所控制,白肋型的基因型并非前人报道的那样只是两对隐性重叠基因,还可能存在一些隐性的微效修饰基因;2.白肋型的叶绿体基粒数及其片层结构均较绿叶型减少,同是隐性核基因突变的结果;3.烟草叶绿体希尔反应活性受核基因的控制。F_1光活性表现明显的杂种优势,是核基因杂合性的反映;4.同前人的研究结果一样,普通烟草RuBp羧化酶的合成受核基因和叶绿体基因的双重控制,但本研究结果指出,白肋型和绿时型之间RuBp羧化酶的大亚基等电点聚焦电泳带存在差異,說明两者控制大亚基合成的叶绿体基因有了一定程度的分化。
