Time-dependent allele effects on root tip angle during gravitropism. The four QTL found by stepwise QTL analyses at each time point that were common to at least two populations were added to a model and the contribution of each locus was estimated. Positive values indicate that substitution of a Cvi allele at the indicated locus increases the tip angle trait, while a negative value corresponds to the Ler allele increasing the trait value. The 95% confidence interval for the degree of the effect is displayed as error bars. (A) Chromosome 1 at 64 cM. (B) Chromosome 3 at 17 cM. (C) Chromosome 4 at 40.3 cM. (D) Chromosome 5 at 61 cM.
