Male scent, likely mediated by ascaroside pheromones, facilitates recovery of fecundity after heat stress.

<p>(A) The protocol for heat stress and recovery experiments is summarized. At 48 hours post L1 arrest (young adulthood) hermaphrodites were singled onto either control or scented plates. Unless otherwise indicated, worms were exposed to scent during both stress and recovery. (B) The fraction of hermaphrodites that recover fecundity after 24 hours of heat stress at 29°C. A schematic is depicted above each condition. **<i>P</i> < 0.01, ***<i>P</i> < 0.001. P-values were calculated using binomial test and Bonferroni corrected for multiple comparisons. Error bars are ±SD among separate trials.
