Connective auxin transport contributes to strigolactone-mediated shoot branching control independent of the transcription factor BRC1
Fig 8
PIN347 and ABCB19 mutation have limited impact on strigolactone response in brc1brc2 mutant branching.
(A) Primary branch number of plants of the genotypes indicated grown axenically on ATS with (orange) or without (grey) 5 μM GR24 in long days, scored after 8 weeks, n = 24–28. The boxes span the first to third quartile and the line represents the median. The whiskers indicate the variability outside the upper and lower quartiles. (B) Violin plots of the relative growth index (RGI) of 2-node explants of the genotypes indicated 10 days post decapitation, with (orange) or without (grey) 5 μM GR24 supplied basally, The RGI is the proportion of branch length in the longest branch. Black dots indicate the median value and the area of each plot represents the probability distribution of the values, n = 20–24. For A and B Tukey’s HSD tests were carried out after obtaining the least-square means for a linear model fitting the data and different letters indicate statistically significant differences at p < 0.05.
