brc1 brc2 mutants are strigolactone sensitive. (A-C) Bud-bud competition assay in which explants bearing two nodes are basally treated with 5 µM GR24 (a synthetic strigolactone) or acetone control and decapitated, n=19-20, error bars are s.e.m. Length of the longer branch (A) or the shorter branch (B) over time after decapitation. (C) Violin plots of the relative growth index (the length of the longest branch divided by the total length of both branches) at day 10 after decapitation, white circles indicate the median and coloured shapes indicate the probability distribution of the data. (D) Total branch number of 6-week-old plants grown axenically on media supplemented with 5 µM GR24 or acetone control. For C and D, asterisks indicate statistically significant differences between treatments for each genotype at P<0.05 with pairwise Wilcoxon rank-sum tests. Data for all panels are representative of three independent repeats.
