Nicotiana tabacum is a member of the Solanaceae, which includes several other vegetable plants like potato, tomato, eggplant and peppers. It is grown for its leaves which contain high levels of nicotine. It is an important experimental plant as it is easy to grow and manipulate in the laboratory. It is extensively used for gene expression studies. More...By-2 cell line established in 1968, by Dr. Kawashima at Hatano Tobacco Experimental Station of Japan, from pith of Nicotiana tabacum L. cv. Bright Yellow No.2 is extensively used in plant gene research.N. tabacum has a large genome of about 4500 Mbp and is an allotetraploid with 2n = 48 chromosomes. According to Kawashima et al., N. tabacum has arisen from a cross between N. sylvestris (2n=24) and N. tomentosiformis (2n=24). Less...
