Toolbar Help

The toolbar is located on the upper portion of the screen on almost every page on the SGN site and provides an easy way to navigate the site. The toolbar consists of the SGN logo and a row of links that link to the main portions of the site. When the mouse passes over a link, a pull down menu is displayed (assuming you have JavaScript turned on). You can either click the main link or scroll down the menu to choose a menu item. If you are having problems with the toolbar, you may want to bookmark this page, and use it instead.

  • Projects -
  • Solanaceae project (SOL) - Over the coming decade the International Solanaceae Genome Project (SOL) will create a coordianted network of knowledge about the Solanaceae family aimed at answering two of the most important questions about life and agriculture: How can a common set of genes/proteins give rise to such a wide range of morphologically and ecologically distinct organisms that occupy our planet? How can a deeper understanding of the genetic basis of diversity be harnessed to better meet the needs of society in an environmentally-friendly way? On this page, you will find more information about the strategy that will be used to answer these questions.
  • SOL-100 Project - The SOL community aims to create a common Solanaceae-based genomic framework that includes sequences and phenotypes of 100 genomes encompassing the phylogenetic diversity of the group.
  • International Tomato Sequencing Project - The gene-rich euchromatic portion of the tomato genome is being sequenced by an international consortium. This page gives more information about the progress of the sequencing effort.
