We are pleased to announce the release of version SL4.0 of the tomato genome and version ITAG4.0 of the annotation. You can find here more information about the assembly and annotation in the preprint on bioRxiv and slides. The genome data is available from our FTP site (Build SL4.0 and ITAG4.0), JBrowse, Apollo gene editor and Blast.

Please use the contact form to let us know if you notice any issues with SL4.0 or ITAG4.0.
