Like all other worm meetings this year, C. elegans evolution meeting will be held virtually . The dates are June 24-25. The schedule sounds exciting with more than 40 talks and 40 posters. There will be 200+ participants. There are also virtual cocktail hours! The details can be found on the website: https://www.evoworm2020.com

This year’s C. elegans topic meeting “Ecology, Evolution and Genomics of C. elegans and Other Nematodes” will be held June 24-27 at McMaster University. Organizers are Te-Wen Lo, Patrick Phillips, Annalise Paaby, and Christian Braendle [Source: wormmeetings@weebly]. Last time the meeting took place at Wellcome Genome Campus (July 5-7, 2018).

The C. briggsae website (briggsae.org) underwent a major change last week. The site has migrated to a new hosting provider and running on WordPress CMS. This represents a significant shift from old-fashioned HTML coding and site management. Going forward, it should be easier to update and maintain the contents.
Ren et al. (2018) report C. nigoni genome sequence assembly and improved C. briggsae assembly
Ren et al. (2018). Genomic basis of recombination suppression in the hybrid between Caenorhabditis briggsae and C. nigoni. Nucleic Acid Research.

The cb4 C. briggsae assembly contains 5,997 gaps (represented by ‘Ns’) and 361 contigs not anchored to any chromosome (‘unassigned’). Ren et al. filled 2,304 gaps by replacing ~240 kbs on six chromosomes and partially closed gaps in ‘unassigned contigs’ and extended ~800 kb sequences. This resulted in a total of ~1,040 kb of new sequence data. The authors also anchored 124 of 361 ‘unassigned’ contigs that added ~1.8 Mb back to individual chromosomes.
