Spontaneous DGU.US recombination in wild-type, <i>rad51b</i>, <i>rad51d</i>, double and triple mutants.

Recombination in the mutants and WT was compared using non-parametric statistical analysis (Mann–Whitney test). Differences between each mutant and corresponding WT are highly significant (p<0.0001). n, the number of plantlets screened; N, the total number of blue spots (recombination events); m ± SEM, the mean number of recombination events per plant ± standard error of the mean.本研究采用非参数统计分析（Mann–Whitney test）对突变体与野生型（Wild Type, WT）的重组事件发生率进行比较。各突变体与其对应的野生型之间的差异均极显著（p<0.0001）。其中，n代表筛选的幼苗株数；N代表蓝斑（重组事件）的总数量；m ± SEM代表每株植株的重组事件平均数±标准误（standard error of the mean）。
