NOTE: Gene counts are very sensitive to the methods used for the prediction as well as the quality of the assembly; the numbers shown represent the best guesses based on the results of the NGASP gene prediction competition. Due to significant residual heterozygosity in the C. remanei and C. brenneri samples, the assembly sizes of these genomes are inflated by roughly 10 and 30% respectively (Eric Haag, personal communication), and the gene predictions are likely inflated by similar amounts.
Nematode annotations and a multiz five-way whole genome nematode alignment (C. elegans, C. briggsae, C. brenneri, C. remanei and P. pacificus) are available at the UCSC Genome Browser. A six-way whole genome alignment that adds C. japonica will be available in July 2008.

C. elegans Isolate Sequencing Efforts
Several groups are resequencing C. elegans isolates for the purpose of identifying SNPs, characterizing the C. elegans population structure, or studying how spontaneous mutations arise in laboratory populations. More information is available in Nematode Resequencing and Diversity.
