Visible light of 5,000 lux intensity has been shown to photokill yeast cells at 12 degrees C. In the present report some of isogenic respiratory deficient mit- and nuclear mutants were compared for their sensitivity to light. No close correlation between the cytochromes spectra and light resistance was observed. Although, the nuclear and rho- mutants which lack cytochromes a + a3 and b are as a rule light resistant. Photokilling effect in yeast seems to be dependent both on the sufficiency of respiratory chain and on protein synthesis probably on cytoplasmic level.
已证明强度为5000勒克斯的可见光在12摄氏度时可光杀死酵母细胞。在本报告中，比较了一些同基因的呼吸缺陷型线粒体和核突变体对光的敏感性。未观察到细胞色素光谱与耐光性之间有密切关联。然而，缺乏细胞色素a + a3和b的核突变体和rho-突变体通常对光具有抗性。酵母中的光杀伤作用似乎既取决于呼吸链的充足性，也可能取决于细胞质水平的蛋白质合成。
