Some examples of extremophiles providing genome- or transcriptome-level data relevant to abiotic stress adaptation. These species are representative of those listed in Table 1. (a) The shores of Lake Tuz in central Anatolia (Turkey) were the original collection site for Thellungiella parvula (b). Note the extensive salt flat where an ephemeral lake would be in a rainy season. (c) Mesembryanthemum crystallinum, known as the common ice plant for the salt crystals excreted from bladder cells on the leaves and stems. (d) Salicornia europaea (a relative of S. brachiata, Table 1) shown in the mud flats at Bull Island, Dublin, Ireland. (e) Heritiera litoralis, one of 27 species in North Queensland, Australia, shown growing along a creek with salinity varying between fresh water and ocean water. (f) Rhizophora mangle, shown as an ocean-fringing forest in the background and as substrate-stabilizing pioneers in the foreground.
