Data from: Neuropeptide signalling shapes feeding and reproductive behaviours in male C. elegans

Sexual dimorphism occurs where different sexes of the same species display
differences in characteristics not limited to reproduction. For the
nematode Caenorhabditis elegans, in which the complete
neuroanatomy has been solved for both hermaphrodites and males, sexually
dimorphic features have been observed both in terms of the number of
neurons and in synaptic connectivity. In addition, male behaviours, such
as food-leaving to prioritise searching for mates, have been attributed to
neuropeptides released from sex-shared or sex-specific neurons. This
dataset compiles the results obtained in our investigation of how LURY-1
neuropeptides regulate feeding and mating behaviours in C. elegans. These
contain confocal micrographs and z-stacks of fluorescence
reporter imaging used to demonstrate the expression pattern
of lury-1 and npr-22, including
micrographs used for cell identification
of lury-1 expressing neurons in the male worm.
Other behavioural data from mating efficiency assays, pharyngeal
pumping assays and food leaving assays are also shown. These include male
turning behaviour examined through video recordings of male mating; the
videos are also included as part of this dataset. In this study
(“Neuropeptide signalling shapes feeding and reproductive behaviours in
male C. elegans”), our findings indicate sex-specific roles of
this peptide in feeding and reproduction in C. elegans.
This provides further insight into neuromodulatory control of
sexually dimorphic behaviours.
