Whole chromosome curvature averages are shown, with the corresponding Standard Deviation (SD). Curvature max. indicates the highest curvature value found in each chromosome, for the cases where this value represented more than 3 Standard Deviation Units (SDU) from the corresponding mean. The z-score measures the distance in SDU from the mean to the maximal value. Chromosome 2 of Arabidopsis and chromosomes 10 and 11 of rice do not present any curvature value above the described threshold.
