Fig 1. Effect of phyB and elf3 mutations on wheat heading time.

(A-B) Long days (LD). (C-D) Short days (SD). (A and C) Kronos photoperiod insensitive (PI) background and (B and D) photoperiod sensitive (PS) background. (E) Effect of the different photoperiods and genetic backgrounds on heading time within each mutant combination. Error bars are s.e.m. Numbers in the base of the bars indicate the number of plants analyzed in each genotype / photoperiod combination. * = P < 0.05, ** = P < 0.01, *** = P < 0.001 (Tukey tests). No statistical tests were performed for the plants that failed to head at 160 d when the experiment was terminated (indicated by gray arrows). Raw data and statistics are in Data A in S1 Data.
