Abscisic Acid—Enemy or Savior in the Response of Cereals to Abiotic and Biotic Stresses?
Abscisic acid (ABA) is well-known phytohormone involved in the control of plant natural developmental processes, as well as the stress response. Although in wheat (Triticum aestivum L.) and barley (Hordeum vulgare L.) its role in mechanism of the tolerance to most common abiotic stresses, such as dr...
