Morphometric data for Jatropha curcas chromosomes.

Data represents the mean ± SD of five replicates from different cells.L: long arm length.S: short arm length.TL: absolute chromosome length.RL (relative chromosome length) = 100 × TL/Total chromosome absolute length;Arm ratio (r = L/S), length ratio between the long and short arms.On the basis of centromere position, the arm ratio (r) was used to classify the chromosomes according to Levan et al. [48] into m, metacentric (r = 1.05−1.69); sm, submetacentric (r = 1.70−2.99); st, subtelocentric (r = 3.00−6.99); and t, telocentric (r = 7.00−39.00).

本数据集数据为不同细胞五次生物学重复的平均值±标准差（Standard Deviation，SD）。其中，L代表长臂长度（long arm length），S代表短臂长度（short arm length），TL代表染色体绝对长度（absolute chromosome length）。RL（相对染色体长度，relative chromosome length）的计算公式为：100 × TL / 染色体总绝对长度；臂比（r = L/S）指长、短臂之间的长度比值。依据着丝粒位置，本研究参照Levan等[48]提出的分类标准，通过臂比（r）对染色体进行如下分类：m为中部着丝粒染色体（metacentric，r=1.05−1.69）；sm为亚中部着丝粒染色体（submetacentric，r=1.70−2.99）；st为亚端部着丝粒染色体（subtelocentric，r=3.00−6.99）；t为端部着丝粒染色体（telocentric，r=7.00−39.00）。
