Manhattan plot of the association analysis for the 11 regular polar radii between the leaf centroid and edge points from -π/2 to π/2.

(A) The plot shows the 19 chromosomes of the reference genome of P. trichocarpa. The horizontal dashed line indicates the genome-wide significance threshold of 5.33, which is a base 10 logarithm of the p-value based on the Bonferroni correction at the 0.05 significance level. (B) The significant SNPs on chromosome 14 were divided into five regions roughly according to the position where the negative logarithm of the p-value changes from decreasing to increasing.</p
