Abstract Low temperature constitutes one of the main barriers to plant distributions, confining many clades their ancestrally tropical biome. However, recent evidence suggests that transitions from temperate biomes may be more frequent than previously thought. Here, we study evolution cold and frost tolerance in globally distributed highly stress-tolerant Salicornieae (Salicornioideae, Amaranth...

Rising sea levels and salinization of groundwater due to global climate change result in fast-dwindling sources of freshwater. Therefore, it is important to find alternatives to grow food crops and vegetables. Halophytes are naturally evolved salt-tolerant plants that are adapted to grow in environments that inhibit the growth of most glycophytic crop plants substantially. Members of the Salico...

This study elucidated O2 dynamics in shoots and roots of submerged Halosarcia pergranulata (Salicornioideae), a perennial halophytic stem succulent that grows on floodprone mudflats of salt lakes. Oxygen within shoots and roots was measured using microelectrodes, for plants when waterlogged or completely submerged, with shoots in light or in darkness, in a controlled environment. Net photosynth...
