At present, none of the scaffolds or contigs from the current public WGS assembly have been placed on chromosomes so you cannot browse the sequence data by chromosome. You can find sequenced regions of interest by querying Map Viewer with a gene symbol or accession number. You can also identify genes of interest by:

  • Searching Gene for Nicotiana tomentosiformis genes and following the link to Map Viewer.
  • Searching the sequence using BLAST against the genome. Results from a BLAST sequence alignment can be displayed in Map Viewer by following the link in 'Related Information' to the right of the alignment.

October 2014, Annotation Release 100

This full annotation run includes the following assembly(ies):

Nicotiana tabacum is an allotetraploid generated after an interspecific hybridization between Nicotiana sylvestris and a member of the section Tomentosae, possibly Nicotiana tomentosiformis. These provide, respectively, the S-genome component and the T-genome component. The effort to develop the syntenic relationships, if any, between tetraploid tobacco and the diploid progenitors has been pursued because of the bread wheat experience. N. tomentosiformis accessions exhibit polymorphism and were used to develop a genetic map of one of the diploid progenitors of N. tabacum.

The NCBI Map Viewer provides graphical displays of features on the genome assembly. Map features that can be seen along the sequence include annotated genes and transcripts, Gnomon-predicted gene and transcript models, aligned transcript and genomic sequences, RefSeq scaffolds (the 'Contig' map), the assembly tiling path (the 'Component' map), and more. For some species, additional non-sequence maps such as Genetic maps, Radiation hybrid maps, and others may be available. Information regarding the N. tomentosiformis mapping projects can be found at the BioProjects website.
