Review: Chloride on the move ($)
Saline soils are an ever growing problem, whether due to seawater incursions, for example in Bangladesh, or due to the rising water table in Australia. Salinity is harmful in three ways: non-specific osmotic effects, excess Na+, and excess Cl–. Of these, chloride has received the least attention. Li et al. review recent insights into the uptake and transport of Cl– into plants, including a review of chloride transporters that move Cl– into and out of the root, xylem vessels, cells and vacuoles. The involvement of ABA in Cl– homeostasis and strategies to increase plants’ tolerance to Cl– toxicity are discussed. Trends Plant Sci. 10.1016/j.tplants.2016.12.004
