A major challenge of the sunflower genome project has been dealing with the large and repetitive nature of the genome. Below is a description of our custom annotation procedures and the results. You may skip to the results or download sections using the menu to the left. Note the references for each data source at the bottom of the page.

Annotation files

Separate transposon and gene annotation files are listed below but note that there are also combined annotation files provided that contain all features (under the section "Combined annotations").
