DNA and RNA from Ancient Plant Seeds
Plant seeds are peculiar structures designed to protect the genetic material of their embryo until long after the death of the mother plant. For this reason, the cells of a plant seed are adapted to survive the most stringent environmental conditions. After prolonged storage, however, a seed loses its capacity to germinate (viability). If the seed is kept in a dry environment it undergoes a sort of spontaneous mummification with no appreciable change in its external morphology. With the passing of centuries it will acquire a dark reddish-brown color, yet show an amazing degree of structure conservation (for a review, see Toole 1986).
