Non-native diseases of dominant tree species have diminished North American forest biodiversity, structure, and ecosystem function over the last 150 years. Since the mid-1990s, coastal California forests have suffered extensive decline of the endemic overstory tree tanoak, Notholithocarpus densiflorus (Hook. & Arn.) Manos, Cannon & S. H. Oh (Fagaceae), following the emergence of the exotic path...
Hybrid lethality is expressed at 28°C in the cross Nicotiana nudicaulis × N. tabacum. The S subgenome of N. tabacum has been identified as controlling this hybrid lethality. To clarify the responsible genomic factor(s) of N. nudicaulis, we crossed N. trigonophylla (paternal progenitor of N. nudicaulis) with N. tabacum, because hybrids between N. sylvestris (maternal progenitor of N. nudicaulis)...
Construction of high-density genetic map and QTL mapping in Nicotiana tabacum backcrossing BC4F3 population using whole-genome sequencing | Zhijun Tong, Sanjie Jiang, Weiming He, Xuejun Chen, Lixin Yin, Dunhuang Fang, Yafei Hu, Fangchan Jiao, Chi Zhang, Jianmin Zeng, Xinfu Wu, Shancen Zhao, Jianbo Jian, Bingguang Xiao Agricultural Journals
A filamentous 750 to 800 nm long virus was isolated from a fig tree with conspicuous symptoms in Yugoslavia. The virus has a very narrow host range; it was transmitted mechanically only to some Nicotiana species including N. megalosiphon and N. sylvestris. It causes the formation of cylindrical cytoplasmic inclusions in infected Nicotiana cells. The inclusions consist of pin-wheels, scrolls and...
گونه phytophthora capsici اولین بار توسط لئونیان در سال 1922 از فلفل در نیومکزیکو جداسازی و توصیف شد. در ایران اگرچه p. capsici از میزبانهای مختلف گزارش شده است، اما اطلاعات دقیقی در خصوص تنوع جمعیت، دامنه میزبانی، ساختار بقا و تیپ آمیزشی این قارچ در دست نیست. این پژوهش به منظور تعیین دامنه میزبانی بیمارگر به ویژه روی گیاهان چوبی انجام شد. دمای بهینه رشد، فراوانی تیپ آمیزشی و تشکیل کلامیدوسپو...

Previous experiments with tobacco (Nicotiana tabacum L. cv Samsun NN) plants revealed that jasmonic acid methyl ester (JAME) induces the expression of a cytoplasmic/nuclear lectin in leaf cells and provided the first evidence that jasmonates affect the expression of carbohydrate-binding proteins in plant cells. To corroborate the induced accumulation of relatively large amounts of a cytoplasmic...
