Abscisic Acid, Stress, and Ripening (ASR1) Gene as a Functional Marker for Salt Tolerance in Durum Wheat.

In semiarid Mediterranean agroecosystems, drought and salinity are the main abiotic stresses hampering wheat productivity and yield instability. Abscisic acid, stress, and ripening (ASR) are small plant proteins and play important roles in different biological processes. In the present study, the ASR1 gene was isolated and characterized for the first time from durum wheat ( L.
