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.”
This study was conducted in collaboration with Malcolm Bennett at the University of Nottingham, U.K. Funding of the portion of this work performed at the Temasek Lifesciences Laboratory was provided by the Singapore National Research Foundation. Research performed at the Carnegie Institution for Science was supported by the Carnegie Institution.
