Mangrove pneumatophore roots engage in salt extrusion
Plant Science Research WeeklyMangroves are salt-adapted trees that provide critical habitats for many organisms and stabilize shorelines. They also have several strategies for dealing with the hostile coastal environment that is high in salt and, for the submerged root system, low in oxygen. Pneumatophores are upward-growing components…
How salt-extruding halophytes avoid drying out
Plant Science Research WeeklyHalophytes are plants that have evolved ways to adapt to high-salt environments that can be toxic to non-halophytes. Some halophytes prevent salt uptake, some sequester it in disposable bladders, and some extrude it from salt glands. In a new study, Mai et al. studied Nolana mollis, a salt-tolerant plant…
