From: Cytokinin functions as an asymmetric and anti-gravitropic signal in lateral roots
Cytokinin signaling integrates environmental signals into angular lateral root growth. a Comparison of the mean GSA distribution and its geographical (latitude) distribution of the phenotyped accessions. T and G allele of CKX2 are depicted in blue and green, respectively. b Relative geographical distribution of the T and G allele of CKX2 in all sequenced Swedish Arabidopsis accessions. The distribution of accessions is visualized by R package “rworldmap”. c, d Representative images and GSA distributions of c Col-0 wild-type and ckx2-1 or d Col-0 wild type and ahk2 ahk4 with and without hypoxia treatment for 4 h. Scale bars, 2 mm. Kolmogorov–Smirnov test P-values: ***P < 0.001 (compared to DMSO solvent or Col-0 wild type control). Mean ± SEM, n = 4 plates (10 seedlings with 60–120 LRs per plate). Experiments were repeated at least three times
