Resumen:
Cold, highsalinity and water deficit are serious abiotic stress restricting plantproductivity throughout the world. Generally, thesethree type of stress cause an osmotic stress, inducing similar damages inplants. In this chapter we review how the primary metabolism of plantsespecially in rice (Oryza Sativa), soybean (Glycine max), andmaize (Zea mays), is affected by stress and their responses. The abioticstress interferes in the growth, cellular elongation, membrane permeability eintegrity, photosynthesis, respiration, ionic homeostasis, moreover causedimbalance with water relations and yield. Plantsrespond and adapt to these stresses in order to survive. The mechanisms includestomata closure, growth and ionic homeostasis regulation, accumulation ofosmoregulators and compatible osmolytes, photoprotection, induction ofantioxidant enzymes and finally a major accumulationthe fatty acid unsaturated and sugars, in particular some of this that seems tobe acting like photoprotective molecules lowering reactive oxygen specieslevels.
