Table showing statistics for predicted gene models from N. tabacum assembly as well as other Nicotiana species and tomato (S. lycopersicum; iTAG v2.30). Data for other Nicotiana species based early access to the N. benthamiana v1.0.1 assembly and re-annotations of the N. sylvestris and N. tomentosiformis genomes [17] using Maker and the publicly available transcriptomic data provided by the N. benthamiana genome sequencing consortium
