The resulting strain, designated YES2MTM1, was transformed with a yeast genomic library. Transformants lost the plasmid overexpressing MTM1 after 5-FOA treatment. Yeast strains able to grow on nonfermentable carbon source with MTM1 deletion and overexpression of some DNA fragments were picked up and candidate suppressor genes were identified. Overexpression of five genes were identified to be able to rescue the growth defect on nonfermentable carbon source. The study will provide reference for MTM1 gene function and screening for suppressor of genes whose deletion result in irreversible damage.

为了避免MTM1缺失造成的不可逆损伤，在野生型酵母中先转入带有MTM1 基因的质粒，再敲除染色体上的MTM1 基因，随后转入基因组文库，再利用药物5-氟乳清酸(5-FOA)迫使细胞丢失表达MTM1基因的外源质粒，再筛选能在非发酵培养基上生长的转化子，通过这种方法筛选发现，POR2等5个基因的过表达可以挽救MTM1 基因缺失造成的非发酵培养基上的生长缺陷，为深入了解MTM1基因的功能提供了线索，对筛选其他造成不可逆损伤的突变基因的抑制基因提供了一条可行的研究思路。
