New Release of WormBase: WS283

WormBase has been updated to the newest release of the site and data, WS283. This is the final release for 2021. Full details are available in the release notes.

Of particular note, we’ve added the first batch of whole gene deletions generated by the Rougvie, Moerman, Hutter and Sternberg labs, expanded our handling of NBRP tm deletion alleles, and refined the presentation of variations.

Please note that there has been a decrease in the number of gene descriptions (-6852) in this release of WormBase; a bug resulted in descriptions with empty sentence templates in genes for which no known protein domains were found.

Non-C. elegans worms no longer display orthologs for human, mouse, and rat; these data are available in Wormbase ParaSite (eg.

The next release of WormBase (WS284) is scheduled for April 2022.

Introducing the Alliance Community Forum

Dear WormBase and Worm Community Forum Users —

As previously discussed, the Worm Community Forum is moving.

Today, along with the Alliance of Genome Resources, we are pleased to introduce a new online discussion forum, the Alliance Community Forum.

Alliance Community Forum

In keeping with the spirit of the Alliance of Genome Resources, we’ve chosen to organize topics by organism and not by Model Organism Database. Rest assured that it’s easy to only follow specific areas that you may be interested in. Worm related discussions, for example, can be found here, subdivided in a variety of topics. You can choose a variety of notifications for topics of interest.

The Alliance Community Forum represents the first place for discussions across six model organism communities — flies, mice, yeast, rats, worms, and zebrafish (from the participating MODs of FlyBase, MGI, SGD, RGD, WormBase, ZFIN, respectively).

We hope that this Forum provides an opportunity for stimulating discussions, finding new collaborations, raising awareness about techniques from other fields, as well as providing a convenient place for posting notes of interest to the broader community of biomedical researchers (meeting details, job postings, funding announcements, etc).

If you are an existing member of the Worm Community Forum

We have migrated most existing accounts. Please reclaim your account on the Alliance Community Forum by requesting a password reset on the new forum. You will be sent a link to reset your password. If you have trouble logging in, please contact

Note that due to a technical issue, if you created an account in the last several months, you will need to create a new account in the Alliance Community Forum.

If you are not an existing member of the Worm Community Forum

You can log in with a new account on the forum, or a Google or Github account if you so choose.

Preserving the Worm Community Forum history

We have migrated [b]most[/b] posts from the nearly 20 year history of the forum. Some posts could not be migrated, nor have posts created in the last few months. Feel free to recreate these topics in the new forum.
