Seeds repair their DNA

I never knew that part of a seed’s development when it first germinates is to repair damage to DNA done as a seed ages.

Seed quality deteriorates with age, and this is associated with accumulation of genome damage. During germination, repair processes are activated to deal with accumulated DNA damage. In particular, single- and double-strand breaks in DNA can be repaired. The DNA damage checkpoint kinase ATM has a major role in integrating progression through germination with repair responses to the DNA damages accumulated by the aged seed.
