heading and maturity under two contrasting photoperiod conditions: (1)
Speed breeding (SB) consisting of 22 h of light and 2 h of darkness, and
(2) normal breeding (NB) consisting of 16 h of light and 8 h of
darkness. GWAS revealed that developmental responses under both
conditions were largely controlled by two loci: PPDH-1 and ELF3. Allelic
variants at these genes determine whether plants display early flowering
and maturity under both conditions. At key QTL regions, domesticated
alleles were associated with late flowering and maturity in NB and early
flowering and maturity in SB, whereas wild alleles were associated with
early flowering under both conditions. We hypothesize that this is
related to the dark-dependent repression of PPD-H1 by ELF3 which might
be more prominent in NB conditions. Furthermore, by comparing
development under two photoperiod regimes, we derived an estimate of
plasticity for the two traits. Interestingly, plasticity in development
was largely attributed to allelic variation at ELF3. Our results have
