Loredana F. Ciarmiello, Pasqualina Woodrow, Pasquale Piccirillo, Antonio De Luca and Petronia Carillo

Plants are exposed to environmental changes, which are perceived as stresses when they are quick and extreme. Drought, salt, and extreme temperatures, in particular, limit agricultural crop productivity, affecting all stages of plant growth and reproduction, and therefore strongly decreasing crop yield. Worldwide estimates show that most yield loss (70%) can be directly due to abiotic stresses. Moreover, the increasing phenomenon of enthronization and the incorrect use of agricultural land have strongly contributed to land degradation. A large number of abiotic stress-responsive ...
