Figure 7. Ectopic expression of the Ler PHYB allele, but not the Cvi-0 allele, reduces chromatin compaction.

Heterochromatin index of phyb9 mutant in the Col genetic background, complemented with gain-of-function PHYB alleles from Cvi-0 or Ler [41] at 200 µmol m⁻² s⁻¹ in short-day photoperiod. Significance levels are compared to phyB9 values; * p<0.05; ns = non significant. Error bars represent SE in al cases.
