Two mutants of Neurospora crassa, uvs-3 and mei-3, share four properties--UV sensitivity, inhibition by histidine, meiotic blockage when homozygous, and increased duplication instability (due to mitotic crossing over, to deletions or to both). The present paper shows that a third nonallelic mutant, uvs-6, exhibits the same four properties.--Also, the instability of duplications in the absence of any UV-sensitive mutant is increased by the presence of histidine in the growth medium.
粗糙脉孢菌的两个突变体uvs - 3和mei - 3具有四个共同特性——对紫外线敏感、受组氨酸抑制、纯合时减数分裂受阻以及重复序列不稳定性增加(由于有丝分裂交换、缺失或两者兼有)。本文表明,第三个非等位突变体uvs - 6也表现出相同的四个特性。——此外,在生长培养基中存在组氨酸时,即使没有任何对紫外线敏感的突变体,重复序列的不稳定性也会增加。
