Harnessing halophyte‐derived allelochemicals and signaling molecules to enhance salinity tolerance in crops

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Soil salinization is a growing global challenge that significantly reduces agricultural productivity by impairing seed germination, growth, and yield. While conventional crops have limited tolerance to high salinity, halophytes are promising biological models for developing strategies to sustain agriculture in saline environments and ...
