Description
Mónica Lugo and co-authors show in 2024 how root fungi help a tropical fern live in salty ground, by becoming its salt vault. The golden leather fern spreads through mangroves and swamps across the tropics. Its partnership with arbuscular mycorrhizal fungi was known from Asia but the mechanism was a mystery.
At the edges of natural hot ponds in Neotropical wetlands, every grown fern examined hosted the fungi. Roots were threaded with fungal strands and feeding structures, and a share of root length was colonized. The surprise sat inside the fungi's storage bubbles: common salt had piled up there, pulled out of the fern's own tissues. Calcium sulfate crystals also formed inside colonized roots. By locking salt away, the authors argue, the fungi let their host fern thrive where salt and heat would otherwise bar it.
