C. elegans germline stem cells become quiescent under starved conditions, and this quiescence maintains the stem cell state even in the absence of GLP-1/Notch signaling, which is otherwise essential for stem cell maintenance.
Morphological and functional rejuvenation upon exit from adult reproductive diapause in C. elegans is independent of germline signaling, but instead involves somatic nucleolar activation and expansion of the RNA pool.
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).
A series of quantitative behavioural and opto-physiological analyses using a novel robot microscope system reveals that C. elegans computes the time-differential and time-integral of sensory information for decision-making during olfactory navigation.
Structure, dynamics, and mutation of a gamete fusion protein and comparisons to viral homologues suggest that after trimerization the domain bearing the membrane-inserting fusion loops can pivot with respect to the trimer 3-fold axis.
