Molecular changes in Mesembryanthemum crystallinum guard cells underlying the C to CAM transition.

KEY MESSAGE: The timing and transcriptomic changes during the C to CAM transition of common ice plant support the notion that guard cells themselves can shift from C to CAM. Crassulacean acid metabolism (CAM) is a specialized type of photosynthesis: stomata close during the day, enhancing water conservation, and open at night, allowing CO uptake. Mesembryanthemum crystallinum (common ice plant) is a facultative CAM species that can shift from C photosynthesis to CAM under salt or drought stresses.

Distribution and re-transportation of sodium in three Malus species with different salt tolerance.

To further dissect the mechanism of salt tolerance in Malus, the comparison was made regarding the differences between the salt-tolerant and salt-sensitive species in sodium accumulation and extrusion capability in the roots and stem base as well as the sodium re-transportation from shoot to roots by using Na labeling-based feeding of leaves and roots-split experiments. The results demonstrated that the salt-tolerant Malus species could accumulate more Na in the main roots, lateral roots, stem base phloem and xylem, and extrude more sodium out than the salt-sensitive one. In addition, the salt-tolerant Malus species had the higher sodium re-transportation rate from shoot to roots.
