BACKGROUND Many species of Nicotiana section Suaveolentes produce inviable F(1) hybrids after crossing with Nicotiana tabacum (genome constitution SSTT), a phenomenon that is often called hybrid lethality. Through crosses with monosomic lines of N. tabacum lacking a Q chromosome, we previously determined that hybrid lethality is caused by interaction between gene(s) on the Q chromosome belongin...
Certain amino acids inhibit growth of tobacco (Nicotiana tabacum L. var. xanthi), tomato (Lycopersicon esculentum) carrot (Daucus carota), and soybean (Glycerine max L. co. Mandarin) cell cultures when nitrate or urea are the nitrogen sources but not when ammonia is the nitrogen source. These amino acids also inhibit development of nitrate reductase activity (NADH:nitrate oxidoreductase EC 1.6....
In flowering plants, RNA editing is a posttranscriptional process that converts specific C to U in organelle mRNAs. Nicotiana tabacum is an allotetraploid species derived from the progenitors of Nicotiana sylvestris and Nicotiana tomentosiformis. These Nicotiana species have been used as a model for understanding the mechanism and evolution of RNA editing in plastids. In Nicotiana species, the ...
Crops drought tolerance is a trait of outmost importance for agriculture especially today when climate change affecting more the production food and feed. The scope this article to evaluate in vitro stress response Nicotiana tabacum L., “Baladi”. experiment was set up four successive stages starting with seedling development, hypocotyl cultivation, three generations micropropagation, pre-acclim...
