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 . (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.
