Mutants with altered ovulation dynamics recover from heat stress differently than the wild type.

(A) Schematic depiction of several key components of Ca²⁺ signaling that regulates ovulation. Modified from [53]. (B) Recovery of fecundity (after a 24-hour heat stress at 31°C) in a mutant with up-regulated Ca²⁺ signaling is lower than in a wild type control (binomial test p = 4.3×10⁻⁹). (C) Recovery of fecundity (after a 24-hour heat stress at 29°C) of mutants or chemical treatment that down-regulate Ca²⁺ signaling is higher than in a wild type control: itr-1 (binomial test p = 7.7×10⁻²⁸), crt-1 (p = 2×10⁻²⁵), and dantrolene (p = 1.6×10⁻⁸). Error bars are s.d.
