Mean DNA yield, mean gene copy numbers, and DNA yield loss-corrected copy numbers for plastid, mitochondrial and nuclear DNA relative to fresh control.

aPercentages were calculated relative to fresh controls, which were set at 100%. Mean DNA yields and mean gene copy numbers were taken from Table S6.
bPercentages of mean gene copy numbers corrected for DNA yield losses relative to fresh control (in brackets) are calculated as: (% mean DNA yield) × (% mean gene copy numbers).
