Abstract

Mutation accumulation in long-lived fairy-ring mushrooms is orders of magnitude lower than predicted based on per-cell division mutation rates in other organisms. A possible explanation is the maintenance of 'immortal' template-DNA in the active periphery of the fairy ring.

摘要

长寿蕈环中的突变积累水平要比其他生物基于细胞分裂突变率预测的低好几个数量级。一种可能的解释是“不朽”的模板 DNA 在蕈环的活跃边缘得到维持。
