Data from: Mutational effects depend on ploidy level: all else is not equal
收藏资源简介:
AbstractPloidy is predicted to influence adaptation directly, yet whether single mutations behave the same in different ploidy backgrounds has not been well studied. It has often been assumed theoretically that aside from dominance, selective parameters do not differ between cells of varying ploidy. Using the budding yeast Saccharomyces cerevisiae, I compared the effect size of 20 adaptive mutations in haploids and homozygous diploids and found, surprisingly, that the same mutations often had a much larger effect in haploids than homozygous diploids. This empirical result demonstrates that it cannot be assumed that mutations will have the same effect in haploids and homozygous diploids., Usage notesTolerance parameter estimates from MLcombined_A_AA_MLc.csvBMN parameters for graphingParameters for data points (colours, position, pch etc.) from Gerstein et al.

【摘要】倍性(ploidy)被认为可直接影响生物适应性,但单突变在不同倍性遗传背景中的表现是否一致,目前尚未得到充分研究。理论上此前通常假设,除显性效应外,不同倍性细胞的选择参数并无差异。本研究以出芽酵母酿酒酵母(Saccharomyces cerevisiae)为实验材料,对比了20个适应性突变在单倍体与纯合二倍体中的效应量,意外发现相同突变在单倍体中的效应往往远大于纯合二倍体。这一实验结果表明,不能想当然地认为突变在单倍体和纯合二倍体中的效应一致。 ## 使用说明 1.
