Hawaiian Caenorhabditis elegans harbor high levels of genetic diversity that might represent the complex patterns of ancestral diversity in the species prior to human influence.
Genetic and behavior analyses show that Caenorhabditis nematodes are lured to the predator Arthrobotrys oligospora by olfactory mimicry of food and sex cues.
C. elegans nematodes use a sensory-neuronal circuit to determine whether to defend themselves from hydrogen peroxide attack or to freeload off orthologous protective defenses from bacteria in their surrounding environment.
A chromosome-wide mechanism balances X-linked gene expression between the sexes in C. elegans, but no similar chromosome-wide mechanism balances gene expression between X chromosomes and autosomes.
A broad mutational target is the cause of the high mutational variance and corresponding fast phenotypic evolutionary rate in P3.p cell fate in Caenorhabditis nematodes.
A new versatile, autonomous, robotic experimental platform (MAPLE) can increase the throughput of biological experiments by automating the growth and phenotyping of a variety of model organisms.
Unexpected structural diversity of nematode small molecules, as revealed by high-resolution phylogenetic analysis, suggests recurrent biochemical innovation, a pattern that is probably typical across animals.
Cellular hallmarks of thermal limits are evolutionarily conserved in nematodes, and changes in surface to volume ratio reflect restricted aerobic metabolism at these limits.
