Table 1. Contribution of the nucleotype and plasmotype
diversity to phenotypic differences between reciprocal hybrids. Tiller
height at two time points and the rate between them, Days to flowering
(DTF), Average Spike dry weight (ASDW), Plant height (PH), Spike length
(SL), spike length CV, Spikes dry weight (SpDW), Total dry matter (TDM)
and Vegetative dry weight (VDW) in the nethouse under ambient
temperature (AT) and high temperature (HT). For clock and Chl F traits:
Amplitude, Period, delta Amplitude (dAMP), delta Period (dPeriod),
Fv/Fm, F/Fmlss, NPQlss and Rfd in SensyPAN under optimal temperature of
22ºC (OT) or high temperature of 32ºC (HT) and the delta HT-OT.
Figure 1. Life history traits, chlorophyll florescence and
circadian clock rhythmicity in barley reciprocal hybrids lines grown
under OT and HT . Mild increase in temperature has significant effect on
plant performance in the field. Distribution and box plot of life
history traits under ambient temperature (AT, black) and high
temperature (HT, gray) in reciprocal hybrid lines (a) Days to
flowering (DTF), (b ) Vegetative dry weight, (c ) Spikes
dry weight (SpDW). Distribution and box plot of mean chlorophyll
florescence traits and clock output rhythmicity: (d) Fv/Fm,
(e ) NPQlss, (f ) Amplitude, and (g) Period,
under optimal temperature (OT, black) and high temperature (HT, gray) in
the reciprocal hybrid lines population. For each student’s t-test, the p
value is depicted as *: P<0.05, **: P<0.01 or ***:
P<0.001.
Figure 2. Proportion of crosses with significant
difference between reciprocal hybrids for phenotypic traits, under OT or
AT and HT. Life history traits include: Tiller height (TH) and tiller
number (TN) at two time points and the rate between them, Days to
flowering (DTF), Average Spike dry weight (ASDW), Plant height (PH),
Spike length (SL), spike length CV (SLCV), Spikes dry weight (SpDW),
Total dry matter (TDM) and Vegetative dry weight (VDW) for plants in the
nethouse under ambient temperature (AT) and high temperature (HT). For
clock and Chl F traits: Amplitude, Period, delta Amplitude (dAMP), delta
Period (dPeriod), Fv/Fm, F/Fmlss, NPQlss and Rfd in SensyPAM under
optimal temperature of 22ºC (OT) or high temperature of 32ºC (HT) and
the delta HT-OT. The mean for each type of traits is depicted: Growth or
reproductive traits in the greenhouse experiment, and clock or Chl F in
the SensyPAM.
Figure 3. Manhattan plots for the Q x E analysis for a)
amplitude and b) period. The genome scan relates to three options of
interactions between markers and environment following (Malosettiet al. 2013). The location of the previously identifiedDOC loci is indicated. Threshold FDR 0.05 is indicated by a red
horizontal line following (Storey & Tibshirani 2003).

between the chloroplastic rpoC1 gene and DOCs loci under OT and
HT conditions Effects for (a) Amplitude for DOC3.2, and for(b) Period for DOC5.1 (c) CNI between DOC3.2
(chr3H_67267835) and rpoC11713 allele for amplitude.(d) CNI between DOC5.1 (chr5H_648981054) and
rpoC11713 allele for period per se (left) and for its
plasticity (right). Different letters indicate the one-way ANOVA test
for significant differences.
