Phenotypic characterization of phyB-null and phyC-null mutants under SD conditions (8 h light/16 h dark). (a) Heading date of WT and phyB-null plants in SD and LD showing the significant interaction between PHYB and photoperiod. Points represent the averages of at least five biological replicates and error bars correspond to SEM. (b) Heading date of WT and phyC-null plants in SD and LD showing the significant interaction between PHYC and photoperiod. Points represent the averages of at least five biological replicates and error bars correspond to SEM. (c) Tiller number per plant. (d) Mean leaf number per tiller. (e) Flag leaf length. (f) Flag leaf width. (g) Internode length and number. Each bar represents an individual plant and the horizontal lines correspond to the position of the nodes. Each internode is represented by a different color, ordered according to their position in the stem. The uppermost segment in each individual represents the length between the last node and the spike (peduncle) (h) Picture of representative plants when phyB-null plants reached heading date, bar = 10 cm. (c to f) Boxplots represent values of at least five biological replications. Different letters indicate significant differences (Tukey’s test P < 0.05). For (a) and (b), * signifies significant differences between photoperiods for each genotype, P < 0.0001. The differences between WT and mutant alleles were also highly significant (P < 0.0001) for both genes and both photoperiods
