A lipid-binding protein mediates both attraction and hypersensitivity to a beetle sex pheromone in a specific type of nematode-insect relationship known as necromeny.
The substrate for evolutionary divergence does not lie in changes in neuronal cell number or targeting, but rather in sensory perception and synaptic partner choice within invariant, prepatterned neuronal processes.
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.
Nematode hermaphroditism has co-evolved with a self-sperm sensing mechanism that protects hermaphrodites from the detrimental effects of mating with males.
Genetic and behavior analyses show that Caenorhabditis nematodes are lured to the predator Arthrobotrys oligospora by olfactory mimicry of food and sex cues.
Nematode sperm respond to competitive environments by modulating cellular pathways involved in migration and storage to ensure their access to oocytes.
Stoichiometric interactions between microtubules and cortical force-generators set spindle size, position and dynamics, and its scaling with cell size in nematode species.
Macrophage dynamics are fundamentally different between two commonly used inbred mouse strains and differences in local resident cell expansion versus monocyte recruitment determine the outcome of tissue nematode infection.
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.
