Upon rehydration, Frullania dilatata resumed full
photosynthetic capability rapidly, whereas Pellia
endiviifolia suffered irreversible damage to photosystem II.
They suggested that F. dilatata likewise possesses a
desiccation-induced production of zeaxanthin, but they
were unable to rule out the loss of K+ from damaged
membranes in Pellia endiviifolia.
