Dear Kathleen,
might be I am one of the people to know about plant ancient DNA.
Charred botanical remains have been so far reluctant to give reliable
genetic information. Bacterial DNA is even more difficult to prove
that you found original DNA (problem of modern comparison, high chnace
to have moern contamination etc). Mostly bacterial DNA is recovered
from things such as ice cores or permafrost (see publications of
Willerslev et al. in Sciene or other journals).
I'll send you more details directly tomorrow, if you wish.
all the best
Angela

>> He asks that curators of such collections fill in the questionnaire
