The Sol Genomics Network (SGN) is a clade-oriented database dedicated to
the biology of the Solanaceae family which includes a large
number of closely related and many agronomically important
species such as tomato, potato, tobacco, eggplant, pepper,
and the ornamental Petunia hybrida.
SGN is part of the International Solanaceae Initiative (SOL), which
has the long-term goal of creating a network of resources and
information to address key questions in plant adaptation and
A key problem of the post-genomic era is the linking of the phenome to the genome, and SGN allows to track and help discover new such linkages.
- Solanaceae and other Genomes
- SGN is a home for Solanaceae and closely related genomes, such as selected Rubiaceae genomes (e.g., Coffea). The tomato, potato, pepper, and eggplant genome are examples of genomes that are currently available. If you would like to include a Solanaceae genome that you sequenced in SGN, please contact us.
- SGN houses EST collections for tomato, potato, pepper, eggplant and
petunia and corresponding unigene builds. EST sequence data and cDNA
clone resources greatly facilitate cloning strategies based on
sequence similarity, the study of syntenic relationships between
species in comparative mapping projects, and are essential for
- SGN assembles and publishes unigene builds from these EST sequences. For more information, see Unigene Methods.
- Maps and Markers
- SGN has genetic maps and a searchable catalog of markers for
tomato, potato, pepper, and eggplant.
- SGN makes available a wide range of web-based bioinformatics tools
for use by anyone, listed here. Some of our
most popular tools include BLAST searches,
the SolCyc biochemical pathways database,
a CAPS experiment
designer, an Alignment Analyzer and browser for phylogenetic trees. The VIGS tool can help predict the properties of VIGS (Viral Induced Gene Silencing) constructs.
The data in SGN have been submitted by many different research
groups around the world which are acknowledged on the corresponding
pages on SGN. If you have data you would like to submit for display
on SGN, please use the contact us web form.

Overview. Entire datasets can also be downloaded from our FTP site.
