2nd Bridging the Divide Workshop to be held at the 2015 C. elegans Meeting

Parasitic Nematodes: Announcing the 2nd “Bridging the Divide” workshop to be held at the 2015 International C. elegans Meeting (June 24th, 2:00pm – 5:00pm, Northwest Auditorium)

Each year infections of animals and plants by parasitic nematodes cause many billions of dollars of agricultural damage. Over a billion people worldwide, particularly in developing nations, are infected by nematodes and suffer from the resulting debilitating diseases. Currently, only a few investigators address problems of parasitic nematodes using C. elegans. To encourage and facilitate more interactions between the C. elegans and parasitic nematode communities, a workshop was held at the 2013 International C. elegans Meeting in which experts in plant, animal and human parasitic nematodes spoke on the life history and unique biology of these parasitic species and on outstanding issues in their field. A key goal of this session was to make C. elegans scientists aware of the issues and problems that parasitic nematode researchers face and pave the way for applying the powerful approaches and technologies that have advanced C. elegans research to parasitic nematodes.

We are hosting a modified version of this session at the start of the upcoming 2015 C. elegans meeting (our session and registration both take place in the afternoon of June 24) in which C. elegans researchers who have worked with other nematodes are invited to share their results and experiences. If you would like to speak at this session, please send your abstract(s) by May 21 to Marty Chalfie.

New in WS246: Curation of Wnt signaling papers

Wnt signaling in C. elegans, both canonical and non-canonical, governs cell polarity and asymmetric cell divisions that ultimately affect endoderm specification, vulva and gonad development, neuroblast migration, neuron branching and outgrowth, formation of the postdeirid sensilla and male tail ray and spicule formation (see WormBook chapters on Wnt signaling for reviews). For the WS246 and WS247 releases of WormBase, WormBase curators have focused on curating papers directly relevant to Wnt signaling in C. elegans. This curation includes Wnt-related genetic and regulatory interactions, anatomy function, mutant phenotypes (by allele and RNAi), expression patterns, Gene Ontology annotations, and cross-species gene orthology and gene models for other nematode species.

WormBook: DNA repair chapter updated

Dear WormBook reader,

Replication and repair by Ann Rose has just been added to the Molecular biology section of WormBook. This chapter updates and greatly expands the 2006 chapter DNA repair by Nigel O’Neil and Ann Rose. Over the past few years there has been an explosion of research using C. elegans to study many aspects of DNA repair and the updated chapter points to several recently published reviews. The new chapter summarizes those reviews and highlights the use of C. elegans in the study of the Fanconi Anemia (FA) repair pathway.

Please proceed to read this chapter and others on nematode biology at http://www.wormbook.org/. If you have any comments or suggestions, please submit them via the Feedback page on wormbook.org.

Thank you for your interest in WormBook.
