Photoprotection of green plants: a mechanism of ultra-fast thermal energy dissipation in desiccated lichens

In order to survive sunlight in the absence of water, desiccation-tolerant green plants need to be protected against photooxidation. During drying of the chlorolichen Cladonia rangiformis and the cyanolichen Peltigera neckeri, chlorophyll fluorescence decreased and stable light-dependent charge sepa...
