The original 100.3 Mb reference genome for Caenorhabditis elegans , generated from the wild-type laboratory strain N2, has been crucial for analysis of C. elegans since 1998 and has been considered co...

C. elegans aggregate in large clumps during feeding. Here, the authors find conserved autism-associated genes mediate distinct molecular and circuit signaling components that tune C. elegans feed...
