Open-source software can untwist images of live Caenorhabditis elegans embryos, allowing epidermal and neuronal cell position and morphology to be examined in previously inaccessible developmental time periods.
Protein binding microarrays highlight the diversification of DNA-binding motifs for the nuclear hormone receptor and C2H2 zinc finger transcription factor families, and reveal unexpected diversity in motifs for the T-box and DM families.
Out breeding depression in Caenorhabditis tropicalis is due to common maternal-offspring incompatibilities that interact with a highly heterogeneous genetic background and may provide a short-term advantage to inbreeding.
Male C. elegans die through two distinct mechanisms – mating-induced germline activation, and potent male pheromone toxicity – but the latter is unique to males of androdioecious species (made up of hermaphrodites and males).
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.
