Transcriptome analysis showed that over-expression CsHD1 and CsHD2 in tobacco resulted in differential expression of hormone biogenesis and signaling genes typically auxin and ethylene.
Matsuoka et al have generated large number of ESTs from N. tabacum BY-2 cell lines to understand the process of changes in plant gene expression during cell division.
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
