Mitotic chromosome stability assay to assess genomic instability in Sde2 mutants. Percentage loss of chromosome 16 in Δ
sde2 strain (Sugioka‐Sugiyama & Sugiyama,
2011) transformed with Sde2 variants is plotted (
n = total number of colonies counted). Processing‐defective and lysine mutants of Sde2 show elevated loss of the chromosome.
