Figure 5- Effects of temperature on circadian rhythms in
phenotypic tails
We selected 10 accessions to represent the phenotypic tails of each
trait as highlighted in Figure 1. Period, phase and RAE in these
accessions were then re-quantified at 10°C, 16°C and 22°C to see if the
tails remained diverged at lower temperatures. In Figure A, light grey
lines show the mean periods of accessions in the long period tail group
with the thick blue line showing the mean period for the whole group.
Black lines show the mean periods for accessions in the short period
group with the thick red line reflecting the mean for the whole short
period group. In Figure B, light grey lines show the mean periods of
accessions with high RAE (low robustness) with the thick maroon line
indicating the overall high RAE tail mean. The black lines show the mean
periods for accessions with low RAE (high robustness). The green line
shows the overall low RAE tail mean. In both Figure A and B the dotted
line is the mean for Col-0 at each temperature.
Figure C shows individual phase estimates from accessions belonging to
the dusk-phased (dark filled point) or dawn-phased (open point) tail
groups plotted as clock plots relative to 24/0 representing dawn. Tail
group phase means are indicated by coloured arrows (dusk tail in orange
and dawn tail in purple). Sample size contributing to accession mean at
each temperature ranged from 14 to 24.)
