Breakthrough: How salt stops plant growth
“Our results mean that in addition to acting as a filter for substances in the soil, the endodermis also acts as a guard, with Abscisic Acid, to prevent a plant from growing in dangerous environments,” said Dinneny.
“Irrigation of agricultural land is a major contributor to soil salinity. And as sea levels rise with climate change, understanding how plants, particularly crops, react to salt might allow us to develop plant varieties that can grow in the saltier soils that will likely occur in coastal zones.”
